What it does, whether the dose matters, and how dogs, cats, rabbits and birds differ." url: https://atoneplace.net/can-pets-eat/chocolate/ site: "At One Place" --- # Can pets eat chocolate? **Chocolate: Toxic — treat as an emergency** Dogs: Toxic · Cats: Toxic · Birds: Toxic > If this has already been eaten, ring your vet or an animal poison control line now rather than waiting for signs to appear — for several of these the window in which treatment works closes before the animal looks unwell. Do not try to make the animal sick at home: home emetics are dangerous for corrosive and petroleum substances and for an animal already showing signs, and salt-based ones have themselves proved fatal. ## By animal | Animal | Verdict | Why | | --- | --- | --- | | Dogs | Toxic | Dose-dependent. Dark and baking chocolate are dangerous in small quantities; milk chocolate needs much more. | | Cats | Toxic | Equally toxic, but cats rarely eat it — they cannot taste sweetness at all, having lost the receptor gene. | | Birds | Toxic | Small body mass makes even a crumb significant. | ## What it actually does The toxic agent is theobromine, a methylxanthine that dogs metabolise very slowly — its half-life in a dog is around 17 hours against a couple of hours in a person. It stimulates the heart and central nervous system, producing vomiting and restlessness first, then a racing heart, tremors and in severe cases seizures. Caffeine, also present, adds to the same effect. The concentration is what matters: cocoa powder and baking chocolate carry roughly ten times the theobromine of milk chocolate, and white chocolate has essentially none. ## How much matters Roughly 20 mg/kg of theobromine produces mild signs, 40–50 mg/kg cardiac effects and above 60 mg/kg seizures. In practical terms about 3.5 g of dark chocolate or 14 g of milk chocolate per kg of dog reaches the mild threshold — so one 100 g bar of dark chocolate is a serious dose for a 10 kg dog and a small worry for a 40 kg one. > Body weight decides almost everything here, so what is trivial for a 40 kg dog can matter for a 4 kg one, and a bird is smaller again. Where a real published threshold exists this page gives it; where none does, it says so rather than inventing one. ## Sweets and baking | Food | Worst verdict | Dogs | Cats | | --- | --- | --- | --- | | Xylitol and birch sugar | Toxic | Toxic | Risky | | Chewing gum | Toxic | Toxic | Risky | | Ice cream | Risky | Risky | Risky | | Honey | Risky | In moderation | In moderation | | Nutmeg | Not safe | Not safe | Not safe | | Cinnamon | Risky | In moderation | Risky | ## Common questions ### Can dogs eat chocolate?
