@Buddys:
Actually, my first B was found running around and was not altered. Always a possibility since the canine need of procreation is pretty darn high up there with food, water, and air…...
Oh I'm sure it does happen and will continue to happen but I just don't see it happening as much as rescues claim it happens. I know for a fact some shelters (the one I worked at did!) will label dogs as rarer breeds to get them adopted faster. We had two scruffy "doodle" mix mutts and the animal warden INSISTED they were Wired haired pointing griffons. LOL.
