Lol! Every animal has their own specific scent anyway. And of course, some of them stink more than others-I used to have a best friend who had the sweetest cat, but he STANK.
But just overall, dogs have a specific scent that I don't like. Even if it's faint, it still bothers me. Same thing with hamsters. My sister used to have a pair of dwarf hamsters. Very cute, but I didn't like their smell.
