I am a bulldog breeder. When I am shopping for a new bulldog to add, I look for puppies with the best pedigree i can afford. Count the number of Champions in their 3-5 generation pedigree. I want to see lots of champions in each generation. Champions in their background tell me a couple of things....1 is that they fit the AKC bulldog standard for conformation and that they look like a bulldog is supposed to look. 2nd is it tells me that these were show dogs who were successful in winning.....they had to be healthy to be in the show ring and healthy background is very important to know. We only purchase and breed multi-champion blood lines for these reasons, as well as other reasons. You want to see both parents, and grandparents if possible. Chances are, they are going to look very much like one of them. The pedigree will also reflect if they are linebreeding or cross breeding, etc.... We do not like to breed daughters to fathers, etc.... Good luck with your search and new ownership of this great breed. They are such a delight.
