Key Takeaways
Poisoned dogs may exhibit gastrointestinal, respiratory, neurological, cardiovascular, and behavioral signs.
It's a medical emergency that must be treated as soon as possible.
Treatment includes induced vomiting, activated charcoal, gastric lavage (if needed), and supportive care.
Summary
Poisoning in dogs happens when a canine ingests, inhales, or even touches a toxic substance. Because dogs are curious and often explore the world with their mouths and noses, this is a common veterinary emergency.
Toxins can easily damage vital organs, the brain, and other crucial bodily systems.
Causes
Common dog poisons include human foods and medications, household chemicals, and plants. Here are some examples according to our veterinary professionals:
Food Poisoning
The foods toxic to dogs should always be avoided, including:
Chocolate. Chocolate, coffee, and caffeine contain methylxanthines, including theobromine, which dogs cannot break down. Dark and baking chocolates are the most dangerous types for dogs.
Grapes and Raisins. These are highly toxic and can result in severe kidney failure. Symptoms may appear 24-48 hours after ingestion.
Onions and Garlic. Onions and garlic, which are part of the Allium family, are poisonous to dogs, whether they are cooked, raw, or powdered. They can destroy red blood cells and cause anemia.
Xylitol. A sugar substitute that causes a rapid drop in blood sugar as it triggers the pancreas to release huge amounts of insulin. It also causes liver failure.
Macadamia Nuts. These nuts are highly toxic and high in fat.
Medication Poisoning
Another common cause of dog poisoning is human medications.
NSAIDs. Ibuprofen, naproxen, and aspirin are common types that may result in stomach upset and kidney damage.
Acetaminophen. A pain reliever that can damage the dog’s liver and red blood cells.
Antidepressants. These medications, including fluoxetine and sertraline, can trigger severe neurological and cardiovascular symptoms.
ADHD Medications. Amphetamines and methylphenidate can cause life-threatening neurological damage.
Alcohol Poisoning
Dogs cannot metabolize alcohol, even in small amounts.
Beer and Spirits. These can cause severe disorientation, low blood sugar, or fatal organ failure.
Rubbing Alcohol. Isopropanol and ethanol are absorbed rapidly through the skin and paws. This causes severe toxicity, skin irritation, and respiratory irritation.
Wine. Along with the alcohol present in wine, it’s also made with grapes.
Chemical Poisoning
These are common household chemicals and products that may poison a dog.
Bleach and Cleaning Agents. These chemicals may burn a dog’s mouth, throat, or stomach when ingested. They can also irritate the skin, eyes, and respiratory tract.
Antifreeze. Antifreeze contains ethylene glycol, an extremely toxic compound used in cars. Its sweet taste may attract dogs, but it may cause metabolic acidosis and severe kidney damage.
Rodenticides. Common types include anticoagulant rodenticides, bromethalin, and cholecalciferol rat poison.
Pesticides. Insect repellants and lawn treatments can cause severe toxicity to dogs when ingested or absorbed through the skin.
Essential Oils. These are highly concentrated substances and are dangerous in pure oil form and in diffusers. Examples include tea tree, wintergreen, and cinnamon.
Plant Poisoning
Some toxic plants can irritate a dog’s stomach and other internal organs.
Sago Palm. Sago palm has a toxin called cycasin, which can cause severe liver damage or death. Every part of the sago palm is toxic to dogs, especially the seeds.
Aloe Vera. While the gel can be soothing for the skin, the latex has saponins and anthraquinone glycosides, which are highly poisonous to dogs.
Oleander. Oleander has cardiac glycosides that can affect the dog’s heart, gastrointestinal tract, and nervous system.
Peace Lily. Peace lilies have insoluble calcium oxalate crystals, which can lead to oral and gastrointestinal issues, pain, and swelling.
Azalea. Azaleas contain grayanotoxins that affect the heart and nervous system, even in small amounts.
Signs of poisoning in dogs
Dogs may experience gastrointestinal, neurological, respiratory, and cardiovascular symptoms when they are poisoned by a toxic substance. The clinical signs and observed symptoms often appear within a few hours of exposure, especially in severe cases.
"Even early signs should be taken as indicators of an emergency, especially if the ingested toxin is unknown. Immediate veterinary care is crucial," says Dr. Angélica.
Gastrointestinal Symptoms. Stomach upset, persistent or severe vomiting and diarrhea (may include blood), excessive drooling, loss of appetite, and increased thirst.
Neurological Symptoms. Lethargy, unresponsiveness, impaired balance, incoordination, restlessness, pacing, tremors, shaking, and seizures.
Respiratory Symptoms. Difficulty breathing, rapid breathing, coughing, and heavy panting.
Cardiovascular Symptoms. Abnormal heart rate, arrhythmias, fluctuations in blood pressure, blue or pale gums, fainting, and collapse.
What to Do
If you think your dog has eaten something toxic, act quickly. Follow these crucial steps:
Remove the Toxin
Take the toxin away immediately so your dog won't consume any more of it. If it's on their fur or paws, you can use an E-collar to prevent them from licking it. Never induce vomiting unless instructed by our vets.
Wash Your Dog
We recommend washing your dog's mouth and skin, depending on where the toxin made contact.
Call the Vets
Once you have secured your dog and the toxin, call an emergency veterinary clinic immediately. Explain everything that happened, and be sure to list down the symptoms you have noticed.
Collect Evidence
Before heading to the clinic, take a picture of the item your dog ingested or touched. This will be helpful when diagnosing and treating your dog.
Seek Emergency Treatment
Rush your dog to the nearest available clinic for immediate care to prevent severe symptoms.
Treating a poisoned dog
If ingested recently, our vets may induce vomiting. “We'll use activated charcoal to bind toxic substances and prevent their absorption into the bloodstream,” says Dr. Angélica. In severe cases, we may perform a gastric lavage with anesthesia to flush out the stomach contents.
For topical exposure, we'll do a complete wash with soap, then saline for the eyes.
The next part of treatment involves IV fluids to flush out remaining toxins and maintain hydration levels. We may prescribe medications for nausea and organ support. Throughout the process, we'll monitor your dog's condition and recovery.
How to prevent poisoning
As pet parents, prevention is the best option to protect our dogs' health. Focus on keeping certain toxic foods, plants, and chemicals away from your dog. It's good to have a dedicated space for household chemicals and human medications.
Having secure containers prevents dogs from rummaging mindlessly and accidentally poisoning themselves.
Avoid giving your dog human foods, especially chocolate, grapes, and raisins. Even small amounts can be dangerous, so it's best to stick with your dog's usual meals and treats.
Remove any toxic plants around the house, as dogs may find ways to reach them even when kept out of reach. Use safe alternatives to decorate your home, such as the money tree and spider plant.
Opt for cleaning solutions and garden treatments labeled pet-safe whenever possible. Keep them away from the room where you are using the chemical.
When outside, watch for dangerous substances such as unknown plants, food trash, wild mushrooms, and chemical puddles.
“The best way to love your dog is to protect the world they explore. Let's start by keeping toxins away from our best friends.”
- Dr. Rokas Proscevicius
Keeping your dog safe from severe poisoning is all about awareness, preparation, and prevention. Dog poisoning can happen at any time, and it’s our job as their pet owners to pay attention to their home, health, and surroundings.
