Can dogs eat milk chocolate?

Toxic: call for help

Short answer: No. Milk chocolate has less theobromine than dark chocolate, but enough to make dogs sick.

Also called or found in: chocolate bar, candy bar, chocolate frosting

Why it matters

The Merck Veterinary Manual lists about 64 mg of theobromine and caffeine per ounce of milk chocolate, versus 150 to 160 mg in dark chocolate.

Mild signs are linked to about 20 mg per kg of body weight, so a 20-pound dog (about 9 kg) is in that range after roughly 3 ounces. The fat in milk chocolate can also trigger pancreatitis in some dogs (Merck).

What owners may notice

Vomiting, diarrhea, thirst, restlessness and hyperactivity, and with larger amounts a racing heart, tremors and seizures (ASPCA, 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

Candy bars, chocolate frosting and chocolate chip cookies count. A poison line can tell you if the amount your dog ate matters.
