Scientific studies have found it takes approximately 15 to 30 grams of garlic per kilogram of body weight to produce harmful changes in a dog’s blood.

There is a lot of space between no effect and getting really sick.
Some mild stomach ache or other kind of discomfort can still be, well, uncomfortable, even if your dog will survive, so don’t feed him shit just because it is not going to kill him.
