The Best Dog Allergy Medicine According to Vets

The best allergy treatment for your dog depends on the severity of their symptoms, the type of allergy, and the frequency of allergic reactions.

Generally, antihistamines are a common way to provide allergy relief for dogs. Just like you might take Benadryl or Claritin for your allergies, these medications can also help your furry friend. However, it’s important to note that antihistamines are only effective in about 30% of dogs, according to research.[1] Another study indicated that 54% of dogs responded favorably to antihistamine treatments. Despite these statistics, there is strong anecdotal evidence suggesting that antihistamines can be effective options for relieving dog allergies.

Antihistamines may initially work well, but they can lose effectiveness over time. Veterinary dermatologist Dr. Nicole Eckholm told Rover, “If an antihistamine is effective, you could continue using it as long as it remains effective. Sometimes, you can manage allergies with just that. Other times, as allergies progress, antihistamines are no longer effective.”[2]

Veterinary dermatologist Dr. Paul Bloom, DVM, DACVD, DABVP, points out that many different antihistamines are available, with none being more effective than another. He recommends trying another antihistamine every 14 days if no improvement is observed until each has been tested for 14 days or an effective one is found.[3]

Corticosteroid therapies (topical or oral) are often the first choice for treating acute (more severe) and chronic inflammatory skin diseases, especially allergic dermatitis.[4] While steroids (corticosteroids) are more powerful and effective at treating allergy symptoms than antihistamines, their long-term use is not recommended due to possible severe and permanent side effects. They are best suited for short-term treatment. Alternatively, nonsteroidal immunosuppressants can be an excellent alternative to steroids for dogs requiring both short-term and long-term treatment, as they do not carry the side effects associated with steroids.

The most effective allergy treatment is immunotherapy (allergy shots), considered the gold standard for managing allergies and halting their progression. The success rate of immunotherapy is between 60-80%, making it the best long-term approach for allergy control.

Natural treatments can also effectively manage dog allergies, but they are generally more suitable for mild cases and prevention.

You must consult your vet to determine the best approach for your pet.

Prevention Is The Best Dog Allergy Medicine

The most effective strategy for managing allergies in dogs is prevention. Dog allergy kits can assist in identifying various types of allergies or intolerances, including those related to food, environmental factors, airborne substances, household items, supplements, medications, and more.

Another practical method to identify what allergens are affecting your pet is through at-home dog allergy testing kits. While these tests should not be used solely to diagnose dog allergies, the results can be invaluable. You and your veterinarian can use these results to create a tailored allergy treatment plan for your dog to avoid ingestion or exposure to potential allergens.

How to Pick The Best Allergy Medicine For Dogs

Identify the symptomsIdentifying the symptoms is the first crucial step in determining if your dog is suffering from allergies. Symptoms to watch out for include excessive itching and scratching, visible signs of skin irritations or infections, frequent sneezing or watery eyes, and behaviors like chewing their paws or shaking their head. More severe signs include hair loss, red bumps, hives, vomiting and discharge.
Consult with a veterinarianBefore administering any medication, it’s crucial to consult with a vet. They can perform allergy tests and provide specific recommendations based on your dog’s needs. The vet may also prescribe specific allergy medicines or recommend over-the-counter options.
Long-term managementConsider making dietary changes if food allergies are suspected. Implement regular grooming and bathing routines to reduce environmental allergens. Ensure your dog’s living environment is clean and free from potential allergens.
Determine the likely causeBy identifying the specific allergen causing the reaction, treatment can be more targeted and effective. Administering general treatments without knowing the cause can be less efficient or counterproductive.
Pick the right treatment optionYour veterinarian should recommend the best dog allergy treatment based on the severity of your dog’s allergies.
Monitor your dog’s responseAfter starting treatment, monitor your dog closely to see if their symptoms improve. Be alert to potential side effects. Some medicines, especially steroids, can have side effects that you’ll want to discuss with your vet.
Regular Vet Check-upEven after finding a solution, regular vet visits are essential to ensure that the treatment remains effective and that no new allergies or health issues have developed.
Every dog is unique, and what works for one might not work for another. It’s always a good idea to approach allergy treatments with patience and veterinarian guidance.

Best Allergy Medicine For Dogs

What’s the best allergy medicine for dogs?

There are quite a few treatments for canine allergies. Some require a veterinarian’s prescription, while others are available over the counter. Whether looking for the best daily allergy medicine for dogs to treat seasonal allergies, a stronger dog allergy med to treat chronic allergy cases, or stopping most dog allergy symptoms, these options can keep sniffles and itchy skin at bay.

1. Prescription Medications

Regarding prescription allergy medicine for dogs, these meds fall into two categories.

  • Nonsteroidal immunosuppressants
  • Corticosteroids

Nonsteroidal Immunosuppressants

Nonsteroidal immunosuppressants are a class of medications that help manage allergies in dogs by suppressing the immune system’s response to allergens. These drugs are beneficial when other allergy treatments, like antihistamines or steroids, have not provided adequate relief. They work by inhibiting specific immune responses that lead to allergy symptoms. They do not have the broad systemic effects of traditional steroids (corticosteroids), making them a safer long-term option for allergy management. Nonsteroidal immunosuppressants are generally safer than traditional steroids, but they can still have side effects such as gastrointestinal upset (vomiting, diarrhea).

Overview
  • Best treatment for: Chronic conditions, such as skin allergies (atopic dermatitis) and environmental allergies.
  • When to use: Great for short and long-term allergy management without the adverse side effects of steroids.
  • Allergy level: Moderate to severe allergic reactions and when other treatments have not been effective.
The Most Common Immunosuppressants

Apoquel

  • Apoquel (oclacitinib): A highly effective against allergies. It begins to relieve itching and inflammation within four hours, and its effects can last up to 24 hours. It’s believed that Apoquel is safer than Atopica. Apoquel is not for dogs with existing parasitic skin infestations or pre-existing cancers.
  • Atopica (cyclosporine): It’s most commonly prescribed for airborne allergies. Atopica takes four to six weeks to provide relief, 

Corticosteroids

Corticosteroids, commonly known as steroids, are a class of medications used to manage allergies in dogs. Corticosteroids work by mimicking the effects of cortisol, a hormone produced by the adrenal glands. Cortisol is a potent anti-inflammatory hormone that helps your dog’s body mitigate the effects of inflammation and other stress-related responses caused by histamine and other pro-inflammatory substances. While these medications stop allergy symptoms, long-term side effects from steroids come with a whole host of adverse side effects, including urinary tract infections (UTIs), susceptibility infections, and obesity, to name a few.

Overview
  • Best treatment for: Typically used for treating anaphylaxis, hives, respiratory distress or severe itching that hasn’t responded to other treatments.
  • When to use: Used for short-term relief of inflammation in chronic conditions. Long-term use is not recommended due to potential side effects associated with long-term use.
  • Allergy level: Severe and acute allergic reactions.
The Most Common Corticosteroids

Prednisone

  • Prednisone: Prednisone is a commonly used oral corticosteroid for dogs. It is available in various forms, including tablets and liquids.
  • Prednisolone: It offers the same benefit as prednisone, but it’s prescribed when liver function is compromised since prednisolone doesn’t need to be converted by the liver.
  • Temaril-P: An oral prescription allergy medication that combines the antihistamine trimeprazine with the steroid prednisolone.
  • Genesis spray: A topical steroid solution for dogs. It contains triamcinolone acetonide and is designed to treat pruritic (itchy) dermatoses in dogs, offering targeted relief.

2. Antihistamine For Dogs Medicience

Nonsteroidal immunosuppressants are a class of medications that help manage allergies in dogs by suppressing the immune system’s response to allergens. These drugs are beneficial when other allergy treatments, like antihistamines or steroids, have not provided adequate relief. They work by inhibiting specific immune responses that lead to allergy symptoms. They do not have the broad systemic effects of traditional steroids (corticosteroids), making them a safer long-term option for allergy management. Antihistamines work by blocking histamines, which are chemicals that the body produces in response to an allergen. When an allergic reaction occurs, the body releases histamines, leading to itching, swelling, and other allergic reactions. By blocking the effect of histamines, antihistamines help reduce or prevent these symptoms.

Best Antihistamine For Dogs

Overview

  • Best treatment for: Dogs suffering from seasonal or environmental allergies.
  • When to use: Typically used to treat allergy symptoms from pollen, grass, insect bites, stings, food and more.
  • Allergy level: Mild to moderate allergic reactions.

Most Common Antihistamines

  • Diphenhydramine: Often known by the brand name Benadryl, it is one of the most commonly used antihistamines for dogs.
  • Cetirizine and loratadine: Zyrtec and Claritin, respectively, are also great for treating allergies in dogs.

3. Over-The-Counter Allergy Medicine

Over-the-counter (OTC) dog allergy medicines are readily available products designed to address various allergic reactions in dogs. Environmental factors, food, insect bites or stings, and more can trigger these reactions. OTC allergy medicines for dogs are typically antihistamines, but there are other OTC allergy meds for dogs you can buy for your dog.

Please note that while OTC allergy medicines can provide temporary relief, they might not address the underlying cause of the allergy. Chronic or severe allergic reactions should be discussed with a veterinarian, who can recommend the best option.

Best Antihistamine For Dogs
  • Best treatment for: For obvious allergic reactions after a walk in a new area trying a new food, or exposure to a specific allergen. It’s great for seasonal allergies as well.
  • When to use: If you know the exact allergen causing the problem for a temporary solution or as a supplementary treatment to your dog’s prescription medicine.
  • Allergy level: Mild to moderate allergic reactions.

4. Topical Treatments

Topical treatments for allergies are products that are applied directly to the skin to alleviate allergic reactions and associated symptoms. These treatments can come in various forms, such as creams, ointments, lotions, gels, and sprays. They are particularly beneficial when there’s itching that doesn’t have a clear origin. Furthermore, these treatments can serve as a supplementary solution alongside systemic treatments, like oral antihistamines.

Overview

  • Best for: Topical allergy treatments are ideal for addressing localized allergic reactions on the skin.
  • When to use: Great for conditions such as eczema, contact dermatitis, itching, rashes, redness, hives, swelling, contact dermatitis and other skin-related allergic reactions.
  • Allergy level: Mild to moderate skin allergic reactions.

The Most Common Topical Treatments

  • Hydrocortisone creams: A mild corticosteroid that can reduce itching and inflammation.
  • Calamine lotion: Provides cooling relief and can help with itching and irritation.
  • Topical antihistamines: Directly counteract histamine’s effects on the skin, but they can occasionally cause more irritation.
  • Anti-allergy shampoo: Specifically formulated to reduce allergens on the animal’s skin and coat.
  • Hypoallergenic wipes: A quick cleaning of the pet’s paws, fur, and skin, especially after walks or exposure to potential allergens.

5. Dog Allergy Shots: Allergen-Specific Immunotherapy

Cytopoint

Allergen-specific immunotherapy, commonly called allergy shots, is designed to desensitize a dog’s immune system to specific allergens. By exposing the dog to controlled amounts of the allergen over time, the immune system is trained to tolerate it without eliciting an allergic response.

The process begins with identifying the specific allergens causing reactions in the dog through allergy testing. Once identified, a specialized serum containing tiny amounts of these allergens is prepared. This serum is then injected into the dog regularly, with the allergen concentration gradually increasing over time. The consistent exposure in controlled doses aims to reduce and eventually eliminate the dog’s allergic response to those substances.

Additionally, this therapy is a preferred alternative when the long-term use of medications, like steroids, is not desirable because of their potential side effects.

Overview

  • Best for: Dogs that have identifiable allergies to specific allergens and have not responded well to other treatment modalities. It is also great for allergens that are difficult to avoid, such as pollen.
  • When to use: If your dog has difficulty with oral medications, chronic allergic reactions that are not sufficiently managed by standard treatments, or if you’re concerned about using them long-term
  • Allergy level: Mild to moderate allergic reactions.

The Most Common Allergy Shots

  • Traditional allergy shot: Before administering shots, your dog needs to be tested to identify the specific allergens. This can be done either through a blood test or a skin prick test. The latter is generally viewed as more accurate and is primarily performed by specialized veterinary dermatologists. Based on the test results, a tailored allergy serum is crafted for your dog. This serum contains small amounts of the identified allergens. This serum is given to your dog through a series of injections. Over time, these shots aim to make your dog less reactive to the offending allergens. Unlike many treatments that manage allergy symptoms, these shots can reduce the frequency and severity of allergic reactions in the long run.
  • Cytopint: Cytopoint is a relatively newer treatment designed for dogs with allergies. Cytopoint is an injectable monoclonal antibody therapy. Unlike traditional drugs that might affect the entire body, Cytopoint specifically targets and neutralizes interleukin (IL)-31, a key cytokine (protein) involved in sending the itch signal to the brain, thus breaking the cycle of itching and inflammation in the dog’s skin. Your local veterinarian can administer Cytopoint and it is generally well-tolerated with a minimal side effect profile.
  • Platelet-rich plasma (PRP) and stem cell therapy for dogs: Historically used to address joint diseases in dogs, both Platelet-rich plasma (PRP) and stem cell therapy have recently emerged as beneficial treatments for canine seasonal allergies.
  • IV vitamin C therapy. IV vitamin C therapy is a relatively new approach to treating allergies. It involves administering a high dose of vitamin C directly into your pet’s bloodstream through an IV catheter. This therapy is especially beneficial if your pet has had adverse reactions to other allergy treatments. IV vitamin C therapy offers anti-inflammatory and antibacterial benefits for your dog. While it isn’t a prescription medication, this treatment still requires the assistance of a veterinarian.

6. Food Elimination Trial

Food allergies or intolerances are present in dogs who have an allergic reaction or sensitivities to the foods they eat. The food elimination trial consists of selecting a special hypoallergenic diet for your pet with the help of your veterinarian. After gradually introducing this new diet over three to five days, you’ll strictly feed your dog this diet for the next eight to ten weeks. During this period, it’s crucial that your dog consumes only this special food—no other treats, human food, flavored medications, chews, or anything else. Only the hypoallergenic food should be given.

After the tenth week, if your dog stops itching on this new diet, it’s a strong sign they may have a food allergy. At this point, you can either continue with the hypoallergenic food or cautiously reintroduce other foods to see if the itching resumes. If you choose to reintroduce the food, you need to do a gradual ingredient reintroduction one by one. If symptoms reappear upon reintroduction, it’s indicative that the dog is allergic or intolerant to that ingredient. Reintroduction of ingredients is key because it lets you pinpoint the culprit ingredient to avoid in the future, so it’s recommended. It’s vital to adhere strictly to what your veterinarian recommends.

Overview

  • Best for: Suggested when a dog persistently displays food allergy or intolerance symptoms.
  • When to use: Dogs experience gastrointestinal disturbances or skin-related issues like itching and rashes due to food allergens, especially when other conventional diagnostic methods such as dog food allergy tests have not provided clear results.
  • Allergy level: Mild, moderate, and severe food allergic reactions.

The Most Common Food Elimination Trials

  • Hydrolyzed protein diets: These diets contain proteins broken down into smaller components made with machines to prevent cross-contamination with allergens, making them less likely to trigger an allergic response.
  • Single novel protein and carbohydrate diets: Examples include duck and potato or venison and peas. These diets use novel ingredients the dog hasn’t been exposed to before.
  • Home-cooked elimination diets: Prepared under veterinary guidance, these diets allow for tight control over ingredients.

7. Environmental Changes

Environmental dog allergy changes refer to modifications in a dog’s surroundings or lifestyle to reduce exposure to allergens. These allergens, present in the environment, can cause allergic reactions in sensitive dogs, leading to symptoms such as itching, sneezing, or even digestive issues. By identifying specific allergens causing the reactions and then eliminating or minimizing the dog’s exposure to them, you can reduce or prevent allergic symptoms. This might involve changes like using specific cleaning products, adjusting outdoor activity timing, or implementing home air filters.

Overview

  • Best for: Dogs that have sensitivities to specific environmental factors like pollen, dust mites, mold, or household chemicals.
  • When to use: Any dog suffering from environmental allergies, especially if symptoms are consistent during certain seasons or in specific environments
  • Allergy level: Mild, moderate and severe environmental allergic reactions.

The Most Common Environmental Dog Allergy Changes For Allergies

  • Frequent cleaning: Regular vacuuming using HEPA filters and washing dog beds/toys in hot water.
  • Air purifiers: Using air purifiers to reduce airborne allergens.
  • Foot baths: Rinsing dog’s paws after walks to remove outdoor allergens.
  • Hypoallergenic bedding: Using allergen-resistant bedding for your dog.
  • Allergen barriers: Using covers or barriers to prevent dust mites.
  • Humidity control: Using dehumidifiers in damp areas to prevent mold growth.

8. Natural Dog Allergy Medicine

Natural dog allergy medicines refer to non-pharmaceutical remedies derived from natural sources intended to alleviate allergy symptoms in dogs. These treatments typically use herbs, natural supplements, and other organic substances believed to possess anti-inflammatory, antihistaminic, or immune-boosting properties. These remedies function by either bolstering the dog’s immune system, counteracting the inflammatory response that allergens produce, or by directly combating the allergens themselves.

Overview

  • Best for: Owners who prefer a holistic approach to their dog’s health may avoid synthetic medications, which they might consider too strong or having undesirable side effects.
  • When to use: As a preventive measure, especially during allergy seasons, and as a supplementary treatment alongside conventional medicine after consulting with a vet.
  • Allergy level: Dogs with mild to moderate allergies.

The Most Common Natural Dog Allergy Medicine

  • Quercetin: A natural antihistamine found in many fruits and vegetables.
  • Omega-3 fatty acids: Typically sourced from fish oils, they help reduce inflammation.
  • Nettle leaf: An herbal remedy with antihistamine properties.
  • Bromelain and papain: Enzymes found in pineapples and papayas, respectively, which increase the absorption of quercetin and help reduce inflammation.
  • Raw local honey: Ingesting small amounts might help dogs develop resistance to local pollens, reducing allergic reactions.
  • Aloe vera gel: Natural remedy is known for its soothing properties.
  • Probiotics: Beneficial bacteria that can boost the immune system and potentially reduce allergic responses.
  • Coconut oil: When added to food or applied topically, it can help reduce allergic reactions and improve skin health.

9. Homemade Dog Allergy Medicine (DIY)

Homemade dog allergy medicines are remedies crafted at home using commonly available natural ingredients. These DIY treatments are often favored by pet owners wary of synthetic pharmaceuticals and prefer a more organic approach to their dog’s health. These treatments usually rely on the inherent properties of natural ingredients to soothe, heal, or prevent allergic reactions. They aim to bolster the dog’s immune response, alleviate symptoms, or create barriers against allergens.

Overview

  • Best for: For mild allergic reactions where over-the-counter medicines might seem excessive or those who have shown a positive response to natural remedies.
  • When to use: As a preventive measure during allergy-prone seasons, a complementary approach, along with other treatments, ensures no adverse reactions.
  • Allergy level: Mild allergic symptoms.

The Most Common Homemade Dog Allergy Medicine (DIY)

  • Chamomile and herbal tea soaks: Can help relieve itchy skin when used as a rinse. The natural qualities of chamomile, calendula, and green tea help treat hot, itchy patches of your dog’s skin.
  • Apple cider vinegar: When diluted and used as a spray, it can act as an anti-itch solution and repel pests.
  • Turmeric paste: Known for its anti-inflammatory properties, can be added to food in small amounts.
  • Oatmeal baths: Can soothe itching and reduce inflammation.
  • Plain yogurt: Yogurt is a beneficial source of protein, calcium, and probiotics for your dog, which can boost your dog’s immune system and gut health. To help relieve itchiness from allergies, add 1-2 teaspoons of plain, sugar-free yogurt to your dog’s food once a day.

10. Epipen (Severe Allergy & Anaphylaxis Shock Injection)

Epipen

The Epipen is a brand of auto-injector that delivers a dose of epinephrine (adrenaline) quickly into the body. It’s primarily used to treat severe allergic reactions, also known as anaphylaxis. When someone, including a dog, experiences a severe allergic reaction, every second counts, and an EpiPen can be life-saving. Epinephrine works by narrowing blood vessels and opening airways in the lungs. This counteracts the severe drop in blood pressure and difficulty breathing during anaphylaxis. The auto-injector mechanism ensures that the medication is delivered rapidly and effectively.

Pet owners must consult a veterinarian before keeping an Epipen for their dogs. They should be trained on the proper use of the device, storage, and the need to seek immediate veterinary care even after its administration. Epipen offers a temporary solution, and a treated individual (or dog) still needs close medical attention following its use.

Overview

  • Best for: Dogs who have a known severe allergy or who have previously experienced an anaphylactic reaction.
  • When to use: When symptoms of anaphylaxis appear, such as difficulty breathing, swelling of the face or throat, a rapid or weak pulse, and hives.
  • Allergy level: A life-threatening allergic reaction.

The Most Common Uses of Epipen

  • Insect stings: From bees, wasps, hornets, or other insects that cause severe allergic reactions.
  • Food allergies: Especially if the dog has shown severe reactions.
  • Medication reactions: Some dogs might have an anaphylactic reaction to specific drugs.
  • Other allergens: Could include substances like certain plants, chemicals, or other less common allergens.

11. Liquid Allergy Medicine For Dogs

The benefits of liquid dog allergy medicine are that they do not require much digestion. They are already broken down, so your body receives the nutrients/medication faster. Here are some of your options.


Other Dog Allergy Treatment Mentions

  • Essential fatty acids for dog allergy treatment. Omega-3 fatty acids can help modulate the immune system. Allergies are essentially the immune system’s overreaction to harmless substances. By helping to regulate the immune response, omega-3s can reduce the severity of allergic reactions. The specific omega-3 fatty acids beneficial for dogs with allergies are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). While dogs can convert GLA (gamma-linolenic acid) and ALA (alpha-linolenic acid)—the fatty acids found in evening primrose oil and flaxseed—they do so inefficiently. They benefit most from fatty acid supplementation derived from fish or krill oil. Additionally, many over-the-counter fish oil products do not have a high enough concentration of omega-3 fatty acids to help with allergies effectively. It’s best to consult your vet for a specific dosage tailored to your dog.
  • Probiotics for dog allergy treatment. Allergies often stem from inflammation and an overactive immune system. A major component of the body’s immune system is located in the gut and is known as the GALT (Gut-Associated Lymphoid Tissue). When the intestines are unhealthy or inflamed, and the gut bacteria are imbalanced, it can contribute to allergies. This is why supplementing an allergic dog with probiotics can be beneficial. Probiotics may help reduce inflammation and restore balance to the gut’s immune system. However, it’s important to use probiotics specifically designed for dogs, as human gut bacteria differ from canine gut bacteria. A product like Vibeful’s Allergy & Immune Support Soft Chews Supplement for Dogs can be a suitable option for canine-specific probiotic supplementation.
  • Dog allergy shampoo. Many dog allergy shampoos contain ingredients like oatmeal, aloe vera, or hydrocortisone that can soothe irritated skin and provide relief from itching and discomfort. Regular bathing with a hypoallergenic or medicated shampoo can help wash away allergens that cling to your dog’s fur and skin. Allergy shampoos often contain moisturizers and essential fatty acids that help restore the natural barrier of the skin. A healthy skin barrier is crucial for protecting against environmental allergens and irritants.
  • Dog flea allergy medicine. Flea Allergy Dermatitis (FAD) is a leading cause of allergic reactions in dogs. This condition arises when a flea bites a dog, introducing its saliva into its skin. The enzymes and peptides in flea saliva can provoke an allergic reaction by stimulating the dog’s immune system and causing skin irritation. For dogs with a flea allergy, even a single bite can cause intense discomfort. To manage flea allergies effectively, it’s crucial to consistently use flea control treatments on all dogs in your household, particularly during flea season. Remember to use products specifically formulated for each type of pet; for instance, do not use a treatment designed for dogs or cats and vice versa.
  • Bacterial and fungal infections allergies. Fungal and bacterial infections can pose significant challenges for dog owners and their pets. These infections frequently coincide with allergies, exacerbating symptoms and discomfort in dogs. Depending on the specific infection, your veterinarian may recommend an antibiotic or antifungal cream. Topical antifungal creams are commonly prescribed for surface fungal infections in dogs. For ear infections or oral treatments, it’s essential to consult your vet for a prescription.

Allergy Medicine For Dogs Dosage

The appropriate allergy medicine dosage for your dog depends on various factors, including the specific condition being treated, the dog’s size and medical history, and the type of medication (such as antihistamines or steroids). The severity of symptoms also plays a crucial role. Each dog requires a tailored dosage; for instance, the amount given to a pug would differ significantly from that given to a Great Dane. It is essential not to administer any medication to your dog without consulting your veterinarian.

What Is The Safest Allergy Medicine For Dogs?

When considering safety and side effects, natural supplements or ingredients are typically the safest allergy medicine for dogs. Antihistamines are the next safest option; they are generally well-tolerated by dogs and rarely cause side effects. Prescription medications are also available, with two primary choices: nonsteroidal immunosuppressants and corticosteroids. Among these, nonsteroidal immunosuppressants are safer, though they may still have more severe side effects compared to natural over-the-counter (OTC) options and antihistamines. Corticosteroids, while effective, have the most severe side effects and are generally recommended only for short-term use.

Best Allergy Medicine For Dogs Reddit

There were tons of Reddit threads on dog allergy meds. Here are the cliff notes and the most recommended alternative on the platform.

It seems that a lot of people on Reddit turn to OTC antihistamines, with Benadryl and Zyrtec being one of the most popular options. Apoquel was also mentioned as a great alternative.
