What Are Pet-Safe Fertilizers?

Traditional lawn care fertilizers use synthetic ingredients and chemicals that may put your family and pets at risk. Fertilizers are often combined with weedkillers (herbicides), pesticides, insecticides, and snail bait. These ingredients make fertilizers toxic if ingested or inhaled by dogs and other pets. You don’t have to worry about exposing your pets to dangerous chemicals with pet-safe fertilizers. A safe fertilizer for pets has an all-natural composition of non-toxic ingredients.

Typically, pet-friendly fertilizers are safe to walk on immediately after application, but always read the label and recommended instructions. To further minimize the risk to your pets, we advise you to water your lawn immediately after applying the fertilizer and wait a couple of days (or as instructed) before letting Fido back on the lawn again.

Pet-Safe Fertilizer Types

The main types of pet-friendly fertilizers are solid, liquid, and granular. None of these types of fertilizer should be ingested or inhaled.

Why Use Pet-Friendly Fertilizers? Benefits

There are several reasons why you may want to use yard fertilizer safe for dogs, including:

  • If your dog is a grass eater, switching to dog-friendly lawn care fertilizer is advised
  • Some pets find fertilizer to be palatable and may eat the product
  • They are a safe alternative used in gardens to enhance the beauty and growth of our plants without harming our pets
  • Avoid fertilizer poisoning in dogs
  • Most pet-friendly lawn treatments do not contaminate the environment
  • If you have dogs who play outside often
  • Avoid unsuspected vet visits

Why Avoid Non-Pet-Friendly Fertilizers?

Are fertilizers safe for dogs? No, traditional (or non-pet-friendly) fertilizers are considered harmful for dogs! Traditional fertilizers are typically mixed with pesticides, herbicides, and other toxic ingredients. Some tragic stories remind us of the importance of using pet-safe lawn care products.

Deanne Wishert tells WYFF News 4 that her two dogs died from pesticide poisoning after playing around a popular Upstate creek in Laurens County.[1] A similar story comes from a professional skater who claims to Newsweek that her dog died after exposure to pesticides sprayed on a neighbor’s lawn. Another more tragic story notes seven dogs died after eating paraquat herbicide in a Portland, Oregon park.[2]

In fact, a study by the National Cancer Institute found that dogs were two times more likely to develop lymphoma if their owners used a popular herbicide on their lawns four or more times a year.[3]

Toxic Ingredients

Are fertilizers toxic to dogs? Yes. A fertilizer that is not pet-friendly can contain harmful substances, including:

  • Herbicides
  • Fungicides
  • Pesticides
  • Iron
  • Sodium
  • Calcium
  • Copper
  • Zinc
  • Ammonium (irritates skin and lungs)
  • Disulfoton (responsible for seizures and pancreatitis)

When consumed in large amounts, these substances can be toxic for dogs. Most lawn fertilizers also include nitrogen, potash, phosphorous, and potassium minerals. These minerals are generally non-toxic to pets.

Fertilizer Poisoning Symptoms In Dogs

If your dog has ingested or inhaled fertilizer, here are some symptoms it could experience.

  • Ulceration in the gastrointestinal tract
  • Redness on the skin
  • Breathing difficulties
  • Tearing and redness of the eyes
  • Vomiting
  • Burns on the pads (if your pet walked through in your fertilizer application)
  • Diarrhea
  • Lethargy
  • Abdominal pain

Take your dog to the vet right away if you suspect fertilizer poisoning. If your dog ingests large amounts, symptoms and complications may be more serious.
