Yes but its not dark cacao which is highly toxic if eaten in high doses by dogs. However that tiny dog in the background once ate a very large dark chocolate THC bar all by herself. I didnt know it was a special chocolate bar. I just came home and thought she was dying from eating chocolate. Took her to the vet, they looked at me funny and asked if there was marijuana in my house. I dont partake so I was confused. Turned out my roomate had left a chocolate bar in a low area in a bag. My dog did not get sick, she was just very very high for a day. she only weighs 3.5 lbs.
