Is Fertilizer Toxic to Dogs? 

Are you worried that your pet may be exposed to dangerous toxins when they go for their daily stroll in the park? You are not alone — many pet owners are concerned about whether fertilizer used on lawns and gardens is hazardous for their four-legged friends. Fertilizers often contain strong chemicals, and ingesting these substances can have adverse effects on animals. Continue reading below to explore the potential dangers of fertilizers to dogs and learn some helpful tips on how best to keep pets safe from any risks associated with them. 

Fertilizer Toxicity 

Fertilizers typically contain a variety of dangerous chemicals. These can include phosphorus, nitrogen, iron, copper, zinc, and much more. And it’s not just the chemicals, fertilizers can also have pesticides, fungicides, and herbicides. Ingesting just a small amount can cause mild stomach upset, while larger amounts can lead to serious poisoning symptoms. If your dog eats a meal-based fertilizer, concretion in the stomach can develop, which can lead to bowel obstruction or severe pancreatitis. 

Symptoms of Poisoning 

If you think your pet might be suffering from fertilizer toxicity, make sure to call your veterinarian and Pet Poison Helpline right away for help. Potential signs of poisoning to watch out for include: 

  • Drooling 
  • Nausea 
  • Vomiting 
  • Diarrhea 
  • Abnormal posture due to abdominal pain 
  • Difficulty breathing 
  • “Muddy” colored gums 


If you suspect that your dog has ingested or inhaled fertilizer, call your veterinarian and Pet Poison Helpline at (855) 764-7661 immediately for first aid advice. Transport your dog to a veterinary clinic so they can receive treatment. This may include inducing vomiting and administering activated charcoal to bind the toxins. Specific treatment will depend on the type and amount of fertilizer ingested. In severe cases, hospitalization may be necessary for supportive care and observation.
