The Negative Effects of Fertilizer on Dogs 

Are you a pet owner who loves spending time in the garden? You’re likely aware of the positive effects that fertilizer can have on your beloved plants and lawn, but did you know that fertilizer can be a health hazard to your dog? Many people don’t give much thought to what kind of dangers are lurking in their yards. Taking the proper precautions and staying informed on common pet toxins is essential for keeping your furry friends happy and healthy. Continue reading below to learn about how fertilizers could negatively affect your dog’s wellbeing. 

Dangers of Fertilizer 

Typically, fertilizers contain a range of dangerous chemicals, such as phosphorus, nitrogen, potassium, iron, copper, baron, manganese, zinc, and molybdenum. They can contain pesticides, fungicides, and herbicides as well, making them even more harmful. Ingestion of small amounts of fertilizer can lead to mild stomach irritation. Larger ingestions can result in a range of poisoning symptoms from nitrogen, iron, and more. If your dog ingests a meal-based fertilizer, a concretion in the stomach can form, leading to bowel obstruction or severe pancreatitis. If you are using fertilizers in your yard or garden, it is crucial to take precautions. If you suspect that your dog has consumed fertilizer, contact your veterinarian and Pet Poison Helpline immediately. 

Fertilizer Toxicity 

If your dog was exposed to any type of fertilizer, it is crucial to seek immediate veterinary care. Potential signs of poisoning include: 

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


If your dog ingested or inhaled fertilizer, contact your veterinarian and Pet Poison Helpline at (855) 764-7661 for first aid advice. Take your pup to the veterinary clinic so they can receive treatment from your veterinarian. Treatment may include inducing vomiting and administering activated charcoal to absorb the toxins. After initial treatment, your veterinarian will determine the proper course of treatment depending on the amount and type of fertilizer ingested. In severe cases, hospitalization may be required to monitor your pet and administer supportive care.
