What is wrong with you people saying chocolate is not toxic to dogs? I’ve seen it first-hand. My chihuahua mix has gotten into chocolate twice (roommates forget and leave food laying around, and he’ll eat anything). Both times were very scary, he was panting a lot, laying on his side on hard floor (which he never does, only carpet), excessively hyper-active, drinking a LOT, and peeing and vomiting a LOT. It was not a pretty sight. He’s gotten into small amounts of chocolate on other occasions, however these were the two times he ate large quantities. Don’t give your dogs chocolate! It’s just not worth it.
