I have read on some of the veterinary sites on the internet that things like garlic and onions can actually kill a dog. The explanation is that dogs cannot deal with some of the chemicals in these and these chemicals will combine with the dogs red blood cells preventing them from carrying oxygen. I think they have the same problem with the oxalic acid in chocolate.You might want to research this carefully before you give your dog garlic.

My husband has been giving all of our dogs minced garlic in their food (1/4 tsp for the Chihuahuas and a full tsp for our lab mix) a few times a week for years. Our first dog that died did so due to old age at 14 years. Had her since a puppy. No fleas, no ticks and no intestinal worms and not one has ever tested positive for heart worms. Fresh uncooked garlic stay away from.
