I use Bug Off Garlic chewables for the dogs for insect repellent and the most they ever smell is their breath after eating them. Smells heavily like a pizzeria lol. As for garlic itself, I don't know. It could be the dog. It could be a reaction. Most people who do garlic only note the smell on the dogs breath but not from the dog themselves.
