i only have 1 dog but she is the alpha dog in the whole neighborhood!!! she is one of the smallest too (the smallest is a shih tzu next door) the rest of the neighborhood consists of husky, german shepherd, lab mixes, other dog mixes and once an akita (they moved away ) the only dog that she fights with over dominancy is our neighbor's friend's dog. she is a chow mix, and is the dominant one in a house of a black and tan coonhound/bluetick coonhound mix and a rescued (very badly abused before they got her ) rottweiler.
