I've never liked anyone who doesn't like dogs.
There is a big difference in the people who like dogs & the people who just like owning dogs. I don't know many people who don't own at least 1 dog, sometimes working dogs, but mostly as a pet for companionship. I've always said that everyone needs at least 1 member of their household who is always happy to see them when they come home !
Back in t'village Collie's are very popular on t'farms even tho' it isn't a sheep area, Lurchers, Spaniels, Retrievers etc often define a mans particular hobby, but most dogs that can be found either out on the walks or in t'pub garden on a sunny evening are the great mix of breeds that make good house dogs with good temperaments.
I don't know anyone who owns an XL Bully, I cannot think of any particular work they are suited to & I understand that they don't make good house dogs. So I guess the majority of their owners just like owning dogs to reflect or extend their personalities.
