Highly Toxic

Chocolate contains theobromine and caffeine. Dogs cannot metabolize these compounds effectively, leading to a buildup that affects the heart, central nervous system, and kidneys.

Toxicity Levels

The darker the chocolate, the more dangerous it is:

Cocoa Powder / Baker’s Chocolate: Most Toxic.
Dark Chocolate: Highly Toxic.
Milk Chocolate: Toxic in larger amounts.
White Chocolate: Low toxicity (mostly sugar/fat), but still unhealthy.

Symptoms

Vomiting and diarrhea
Rapid breathing and panting
Increased heart rate
Seizures

Action: If your dog ingests chocolate, call your vet immediately. Have the wrapper ready to tell them the type of chocolate and how much was eaten.
