How common is it to find an English bulldog puppy in the shelter?

The chances of you finding an English bulldog puppy at a shelter are extrremely low. This is largely because of the organization B.C.A.R.N (Bulldog Club of America Rescue Network) which rescues bulldogs and bulldog puppies from shelters and puts them into foster homes until a suitable home is found. Another reason why finding an English bulldog puppy in a shelter is rare is because bulldogs are very expensive. So for example if someone were to buy a $2,000 bulldog puppy, and had to get rid of it because they're allergic, usually aren't willing to give the dog to an animal shelter when they could, instead, sell him/her and get some of their money back.
