Can dogs eat dark and baking chocolate?

Toxic: call for help

Short answer: No. Dark and unsweetened baking chocolate are the most dangerous chocolates for dogs.

Also called or found in: unsweetened chocolate, semisweet chocolate, bittersweet chocolate, chocolate chips, cacao

Why it matters

Chocolate contains theobromine and caffeine. Dogs are sensitive to both (ASPCA).

The Merck Veterinary Manual lists about 440 mg of these compounds per ounce of unsweetened baking chocolate and 150 to 160 mg per ounce of semisweet or dark chocolate.

Merck links about 20 mg per kg of body weight to mild signs, 40 to 50 mg per kg to heart effects and 60 mg per kg or more to seizures. For a 20-pound dog (about 9 kg), roughly 1 ounce of semisweet chocolate reaches the mild-sign range and about 2½ ounces the heart-effect range. Chocolate's fat can also trigger pancreatitis in some dogs.

What owners may notice

Vomiting, diarrhea, thirst, restlessness, panting and hyperactivity, then a racing heart, tremors and seizures in larger doses (ASPCA, Merck).

Signs usually start 6 to 12 hours after eating (Merck).

This list can't tell you if your dog is OK. Only a veterinarian can.

If your dog ate some

Call your veterinarian or an animal poison line now: ASPCA Animal Poison Control Center (888) 426-4435 or Pet Poison Helpline (855) 764-7661. Have the package, the amount and your dog's weight ready. Don't try home remedies unless your veterinarian or the poison line tells you to.

In the kitchen

Chocolate chips, brownie batter and melted chocolate on a cooling rack are the classic kitchen accidents. Keep them pushed back on the counter.
