Yes, dogs can eat peanut butter in moderation, and this tasty treat can offer some health benefits. However, before adding peanut butter to your pup’s diet, there are a few important factors to consider. While small amounts of natural, unsweetened peanut butter are generally safe, some store-bought varieties contain xylitol, a toxic ingredient for dogs. Plus, what about reduced-fat peanut butter? Is organic peanut butter better? Can too much peanut butter cause health issues? This guide will explore the benefits, potential risks, and the safest way to incorporate peanut butter into your dog’s diet.

Is Peanut Butter Good For Dogs?

Yes, if given in moderation, peanut butter can be a tasty and nutritious treat for dogs. Choose natural, unsweetened peanut butter when possible, as it avoids harmful additives like xylitol, which is toxic to dogs.

Peanut butter provides a natural source of protein and healthy fats, which help support muscle growth and energy levels.
It contains vitamins and minerals such as vitamin B6, vitamin E, niacin, folic acid and magnesium, contributing to overall health.
Peanut butter is a great source of fiber, which can support digestive health when given in appropriate amounts.
Many dogs love the taste, making peanut butter useful for training, stuffing in toys, or disguising medication.
Observational studies indicate that eating peanuts may protect against heart disease.^[1]

The ideal peanut butter for dogs should contain only peanuts. However, a little salt or sugar may also be acceptable and safe. The healthiest option is unsalted (no sugar) homemade peanut butter. Unfortunately, not every dog parent has the time to make peanut butter at home. The best alternative is to give dog-friendly peanut butter made by animal nutritionists.

Given its high-calorie content, peanut butter should be given as an occasional treat rather than a regular part of a dog’s diet to prevent potential weight gain and related health issues.

Risks & Considerations Before Feeding Peanut Butter to Dogs

Peanut butter can be safe and beneficial for dogs when consumed in moderation due to its nutritional values, but it also poses risks. Here are the considerations to keep in mind:

Xylitol toxicity: Some peanut butters contain xylitol, a sugar substitute that’s highly toxic to dogs. Even small amounts can cause rapid insulin release, leading to hypoglycemia (low blood sugar), seizures, tremors, disorientation, liver failure, or even death. While Xylitol is safe for people, it can be deadly to dogs.^[2]
Brands to avoid: The peanut butter brands Go Nuts, Hank’s Protein Plus Peanut Butter, Krush Nutrition, Nuts ‘n More, and P28 have been reported to contain xylitol, a sugar substitute that is toxic to dogs.
Check the label: When checking ingredient labels for xylitol—a sugar substitute toxic to dogs—be vigilant for terms containing “xyl,” as they often indicate its presence. Synonyms for xylitol include: 1,4-Anhydro-D-xylitol, Anhydroxylitol, Birch bark extract, Birch sugar, D-xylitol, Xylite, Xylitylglucoside and Zylatol.
High-fat content: Peanut butter is calorie-dense and rich in fats. Excessive consumption can contribute to obesity and increase the risk of pancreatitis—a painful and potentially life-threatening inflammation of the pancreas.
Added sugars and salt: Many commercial peanut butters contain added sugars (caramel, corn syrup, molasses, xylitol), and salt, which aren’t beneficial for dogs. High sugar consumption in dogs can lead to obesity and diabetes, while high sodium intake can lead to health issues, especially in dogs with existing kidney problems.
Health issues not suitable for peanut butter: Dogs with pancreatitis or those prone to the condition should avoid peanut butter due to its high-fat content, which can trigger pancreatitis episodes. Similarly, due to its potential impact on blood sugar, it’s best to consult your veterinarian before offering peanut butter to a diabetic dog.

Other Ingredients to Avoid

Mono and diglycerides: These are added as emulsifiers and preservatives but can lead to unhealthy weight gain and heart health problems in dogs due to their fat content.^[3]
Hydrogenated vegetable oils (trans fats): Trans fats are harmful to dogs’ cardiovascular health, increasing the risk of pancreatitis, high cholesterol, and heart disease. They can also contribute to conditions like Cushing’s disease and hypothyroidism.
Palm oil: While not inherently toxic, palm oil’s high-fat content can cause gastrointestinal distress, pancreatitis, or even intestinal blockages if consumed in large amounts.

Are Dogs Allergic to Peanut Butter?

Most dogs are not allergic to peanut butter, and it’s generally considered safe for canine consumption. However, some dogs may develop an allergic reaction like with any food. Food allergies in dogs typically manifest as itchy skin, hives, infections, and anaphylaxis (a medical emergency) in severe cases. If you suspect your dog is having an allergic reaction to any food, including peanut butter, it is crucial to consult a veterinarian.

Additionally, conducting an at-home dog allergy test like the 5Strands can help determine if your dog is allergic or intolerant to certain foods. For a more comprehensive approach, consider an at-home dog gut health test, like the Embark Gut Health Test, which can provide deeper insights into your dog’s digestive health and immune function. These tests can identify food sensitivities, bacterial imbalances, and other underlying issues contributing to allergies, helping you take proactive steps to prevent discomfort and support your dog’s overall well-being.

Risks

The following symptoms may indicate a bad reaction to peanut butter.

Discomfort and bloating
Gas
Upset stomach
Diarrhea
Vomiting
Loss of appetite
Lethargy

What to Do If A Dog Reacts Badly to Peanut Butter

Dogs showing worsening symptoms, such as blood in their vomit or stool, difficulty breathing, weakness, or collapse, should be taken to the veterinarian immediately.

1. Contact a veterinarian immediately: Even if your dog seems fine, contact your veterinarian or an emergency pet poison hotline right away. This includes services like the ASPCA Animal Poison Control Center or Pet Poison Helpline at 1-855-764-7661. If you can’t reach your vet, you can chat live with a registered online veterinary professional via our online vet chat or video chat support (24 hours a day, 7 days a week). You can also schedule an at-home veterinary appointment with The Vets, a mobile veterinary service that provides at-home vet care nationwide for just about everything.

2. Gather important information:.When speaking to a vet, provide: Quantity consumed (estimate if unsure), time of ingestion and dog’s weight and breed (to assess potential risk).

3. Follow veterinary instructions: The vet may suggest monitoring at home, or emergency treatment at the clinic.

Keep your dog calm and prevent them from eating anything else.
Be prepared to transport your dog to the vet quickly if advised.
Bring any remaining peanut butter or packaging to help the vet assess the situation.
