Common Dog Toxins to Look Out For
Dogs are naturally curious creatures, often exploring the world with their noses and mouths. While this behavior is endearing, it can also lead them into danger, particularly when it comes to dog toxins. In this blog, we’ll discuss various substances that can be harmful to dogs, their symptoms, and what actions to take if you suspect your dog has been exposed. For immediate concerns, call Prairie Animal Hospital at (309) 981-5112 or your nearest emergency vet.

Household Items That Are Toxic to Dogs
Cleaning Products
Bleach, ammonia, and phenols are common ingredients in household cleaning products that can cause severe health issues. Ingesting these substances can lead to symptoms such as drooling, vomiting, and difficulty breathing. Even skin contact can cause irritation and burns. To keep your dog safe, store cleaning products out of reach and use pet-friendly alternatives whenever possible.
Human Medications
Over-the-counter and prescription medications can be extremely harmful to dogs, even in small doses. Pain relievers like ibuprofen and acetaminophen, antidepressants, and medications for human heart conditions can cause serious health problems. Symptoms of medication poisoning in dogs include vomiting, diarrhea, lethargy, and seizures. Always keep medications securely stored and never administer human drugs to your dog without veterinary advice.
Food Items
Certain foods that are harmless to humans can be toxic to dogs. Some common food toxins include:
Chocolate
Chocolate contains theobromine, which is highly toxic to dogs. The darker the chocolate, the higher the theobromine content. Symptoms of chocolate poisoning include vomiting, diarrhea, rapid breathing, and seizures.
Grapes and Raisins
Grapes and raisins can cause kidney failure in dogs. Even small amounts can be harmful. Symptoms include vomiting, lethargy, and decreased appetite.
Onions and Garlic
Onions and garlic, whether raw, cooked, or powdered, can damage a dog’s red blood cells, leading to anemia. Symptoms include weakness, vomiting, and breathlessness.
Outdoor Hazards
Plants
Several plants commonly found in gardens and homes are toxic to dogs. Some of the most dangerous include:
Sago Palm
Every part of the sago palm is toxic to dogs, especially the seeds. Ingestion can cause liver failure, with symptoms such as vomiting, diarrhea, and seizures.
Oleander
Oleander is highly toxic, and even small amounts can cause serious health issues, including heart problems. Symptoms include drooling, abdominal pain, and irregular heartbeats.
Lawn and Garden Products
Fertilizers, pesticides, and herbicides contain chemicals that can be harmful to dogs. Cocoa mulch, which can be used in gardens to improve the soil, contains theobromine and has more toxins in it than edible chocolate. Ingesting these products can lead to symptoms such as vomiting, diarrhea, and seizures. Ensure that your dog does not have access to treated areas.
Chemical Hazards
Antifreeze
Antifreeze (ethylene glycol) is a common toxin due to its sweet taste, which attracts dogs. Even a small amount can be deadly, causing kidney failure. Symptoms of antifreeze poisoning include vomiting, increased thirst, and lethargy. Immediate veterinary care is necessary if antifreeze ingestion is suspected.
Rodenticides
Rodenticides, or rat poisons, contain chemicals that can cause internal bleeding, kidney failure, or neurological damage. Symptoms vary depending on the type of rodenticide but often include bleeding, weakness, and seizures. If you use rodenticides, make certain they are placed where your dog cannot access them.
Marijuana and Cannabis Products
Marijuana, also known as weed, Mary Jane, pot, and several other names, contains THC (tetrahydrocannabinol), which is toxic to dogs. Ingesting marijuana can lead to symptoms such as vomiting, lethargy, incoordination, drooling, tremors, and seizures. Edible cannabis products, which often contain high levels of THC and other toxic ingredients like chocolate or xylitol, can be particularly dangerous.
What to Do If You Suspect Poisoning
If you suspect your dog has ingested a toxin, act quickly. Remove your dog from the source of the toxin and prevent further exposure. Do not induce vomiting unless instructed by a veterinarian. Call Prairie Animal Hospital at (309) 981-5112 or your nearest emergency veterinarian for immediate assistance.
Emergency Veterinary Care
Bring your dog to the vet as soon as possible. Provide as much information as you can about the potential toxin, including packaging if available. Early intervention can significantly improve your dog’s chances of recovery.
How to Protect Your Dog From Common Toxins
- Safe Storage: Store all hazardous substances out of reach of your dog. Use child-proof locks if necessary and ensure that guests and family members are aware of the dangers of leaving items like medications and food within your dog’s reach.
- Pet-Safe Alternatives: Consider using pet-safe products for cleaning and gardening. These products are designed to be less harmful to pets and can reduce the risk of accidental poisoning.
- Supervision and Training: Supervise your dog when they are outdoors or in unfamiliar environments. Training your dog to avoid certain areas or substances can also help prevent accidental ingestion of toxins.
By staying informed of potential dog toxins and remaining vigilant, you can help ensure your dog’s safety and well-being from these harmful items. If you have any concerns or need further information, contact Prairie Animal Hospital at (309) 981-5112.
