Chocolate, grapes, antifreeze, houseplants: many substances that are perfectly harmless to humans turn out to be toxic, even fatal, to dogs — basic knowledge that can literally save a life.
The most common food poisonings
Chocolate
The theobromine it contains is toxic to dogs. The darker the chocolate, the higher the concentration — a square of dark chocolate poses a markedly higher risk than the same amount of milk chocolate.
Grapes and raisins
Documented kidney toxicity, with a worrying particularity: the toxic dose varies enormously from one dog to another, making any prognosis difficult even for a small amount ingested.
Onion, garlic and shallot
Cause destruction of red blood cells, with effects sometimes delayed by several days after ingestion.
Xylitol
A sweetener found in many chewing gums, candies and some peanut butters — causes a sudden drop in blood sugar and liver damage. It is one of the most rapidly serious poisonings.
Alcohol and caffeine
Toxic even in small amounts relative to the dog's size.
Non-food poisonings
Antifreeze (ethylene glycol)
Its sweet taste attracts dogs. Extremely toxic to the kidneys, with a very short window for treatment — an absolute emergency.
Rodenticides
Cause internal bleeding, often with symptoms delayed by several days.
Certain indoor and garden plants
Oleander, lily of the valley, yew and many others present varying degrees of toxicity — checking beforehand is essential before introducing a new plant into a household with a dog.
Human medications
Ibuprofen and paracetamol, often given by well-meaning owners, are highly toxic to dogs — a reminder that directly echoes what we discussed in our article on managing chronic pain.
General warning signs
Vomiting, diarrhea, excessive drooling, tremors, sudden lethargy, seizures, breathing difficulties, disorientation — since symptoms vary so much depending on the substance, mere suspicion of ingestion is enough to warrant an immediate call to the vet.
What to do
1. Contact a veterinarian or animal poison control center immediately, without waiting for symptoms to appear
2. Identify the substance and the approximate quantity if possible — keeping the packaging helps considerably
3. Never induce vomiting without explicit veterinary instruction: certain substances (caustic products in particular) cause more damage coming back up
4. Never give a home remedy without professional advice
Prevention, as always
As mentioned in our article on the first-aid kit, having the contact details of an emergency vet and an animal poison control center on hand is part of basic preparation — just as important as physically securing access to hazardous substances.
