Intoxications et sécurité alimentaire

Aliments · Dangereux pour les chien & chats

Contains theobromine, which dogs metabolize very slowly. Dark/baking chocolate is the most dangerous — 100g of dark chocolate reaches toxic levels for a 15kg dog. Cats are more sensitive but rarely volunteer to eat it.

Aliments · Dangereux pour les chiens

Can trigger acute kidney failure in dogs, with no established safe dose — some dogs are poisoned by a single grape. Raisins are concentrated and even more dangerous.

Aliments · Dangereux pour les chiens

Triggers a massive insulin release causing abrupt hypoglycemia in dogs; larger doses cause acute liver failure. A single piece of sugar-free gum can drop a small dog's blood sugar. Cats are rarely affected.

Plantes · Dangereux pour les chats

Every part is lethal to cats: petals, leaves, stems, even pollen and the vase water cause acute kidney failure. A few licked pollen grains can be fatal. In dogs, lilies usually cause only mild GI upset.

Plantes · Dangereux pour les chien & chats

The whole plant contains cardiac glycosides — a few leaves can kill. Common in southern urban landscaping; watch on walks.

Plantes · Dangereux pour les chien & chats

The entire plant is deadly; the seeds are the most toxic part, causing acute liver failure. Common as a potted or garden plant, and dogs chew it readily.

Produits chimiques ménagers · Dangereux pour les chat & chiens

Cats can barely metabolize it — a single 500mg tablet is lethal; toxic doses in dogs are low too. The most classic household poisoning: owners giving human medicine to a sick pet.

Produits chimiques ménagers · Dangereux pour les chien & chats

Causes GI ulceration and acute kidney failure; cats are extremely sensitive. Pain relief must use pet-specific medication.

Produits chimiques ménagers · Dangereux pour les chien & chats

Common anticoagulant types destroy clotting — bleeding starts 3-5 days later and is easily missed; eating a poisoned rodent can cause secondary poisoning.

Produits chimiques ménagers · Dangereux pour les chats

A cat's liver cannot metabolize permethrins. Applying a dog spot-on to a cat — or a cat licking it off the dog — causes severe tremors and seizures within hours. One of the most classic cat poisonings.

Produits chimiques ménagers · Dangereux pour les chien & chats

Ethylene glycol tastes sweet, so animals drink it willingly. Tiny amounts cause acute kidney failure (1-2 teaspoons can kill a cat); garage floor drips are the main source.

Produits chimiques ménagers · Dangereux pour les chien & chats

One cigarette butt can poison a small dog; e-liquid is far more concentrated — one bite into a pod is dangerous.

Plantes · Dangereux pour les chien & chats

Seeds contain ricin — one or two chewed seeds can be fatal; common as an ornamental in some regions.

Plantes · Dangereux pour les chien & chats

Contains colchicine throughout — among the most toxic garden bulbs, causing multi-organ failure with no antidote.

Produits chimiques ménagers · Dangereux pour les chiens

Produits chimiques ménagers · Dangereux pour les chien & chats

Field/garden spray residue and illegal poison baits often contain organophosphates — cholinesterase inhibitors; licking sprayed grass or bait poisons fast.

Produits chimiques ménagers · Dangereux pour les chien & chats

A deadly herbicide — licking sprayed foliage poisons, causing irreversible pulmonary fibrosis and kidney failure with no antidote and very high mortality.

Produits chimiques ménagers · Dangereux pour les chiens

A major risk when hiking grassy woodland. Bite sites (face/forelimbs) swell fast; venom type decides neurologic vs blood signs.

Plantes · Dangereux pour les chien & chats

Contains cardiac glycosides (the source of the heart drug digoxin) — ingestion causes severe arrhythmia; beware in ornamental gardens.

Produits chimiques ménagers · Dangereux pour les chien & chats

A button battery lodged in the esophagus burns through tissue within 1-2 hours; cracked dry cells leak corrosive alkali. Found in remotes, toys, scales.

Aliments · Dangereux pour les chien & chats

Plantes · Dangereux pour les chien & chats

Everything except the red aril flesh contains taxine alkaloids that depress the heart — a few leaves can cause sudden death; common as hedging, dogs chew it.

Plantes · Dangereux pour les chien & chats

The whole plant holds cardiac glycosides (same family as oleander) — flowers, leaves and even vase water are dangerous; small amounts cause arrhythmia.

Plantes · Dangereux pour les chien & chats

Produits chimiques ménagers · Dangereux pour les chien & chats

Licking paint chips during renovation or from old furniture accumulates chronic lead poisoning; young animals are more sensitive.

Aliments · Dangereux pour les chien & chats

The flesh is harmless — the danger is cyanogenic glycosides in pits, leaves and stems (releasing cyanide when crushed). Whole swallowed pits also risk obstruction.

Produits chimiques ménagers · Dangereux pour les chat & chiens

Cats lack the enzyme to metabolize phenol-rich oils (tea tree, peppermint, citrus) — licking contaminated fur or breathing active diffuser aerosols can poison; dogs are sensitive to tea tree too.

Aliments · Dangereux pour les chien & chats

Large salt intake (one bag of salty chips exceeds a small dog's limit; salt play dough is the classic case) causes hypernatremia — brain cells dehydrate, producing neurologic signs.

Produits chimiques ménagers · Dangereux pour les chiens

Cocoa-shell garden mulch smells like chocolate and attracts dogs; it contains the same theobromine — treat exactly like chocolate poisoning.

Produits chimiques ménagers · Dangereux pour les chiens

Dogs love chewing coins (post-1982 US pennies are zinc-heavy) and small hardware — stomach acid dissolves zinc causing hemolytic anemia; coins show on X-ray.

Produits chimiques ménagers · Dangereux pour les chiens

Human iron preparations (especially prenatal vitamins) are metal-toxic to dogs — GI corrosion then delayed liver failure and metabolic acidosis.

Aliments · Dangereux pour les chiens

Moldy nuts and black walnuts can contain tremorgenic mycotoxins (tremors, seizures) or aflatoxin (liver damage). Peak risk: fall foraging under walnut trees.

Aliments · Dangereux pour les chiens

Calcium oxalate plus soluble toxins double the insult — chewing causes intense oral pain and swelling, sometimes airway edema (hence the folk name dumb cane).

Plantes · Dangereux pour les chien & chats

Also an Araceae oxalate irritant (not a true lily — no kidney toxin), but oral irritation is still pronounced.

Plantes · Dangereux pour les chien & chats

A common indoor Araceae vine — oxalate crystals irritate mouth and gut, same family as pothos.
