I purchased one of my dogs from a very "reputable" breeder, who has shown bulldogs for over 20 years, and who was listed as a recommended breeder by the bulldog club I was refereed to by the AKC. Both the US and State bulldog clubs showed this person as a "recommended breeder". I paid A LOT of money for my girl assuming, like you, that this champion breeder would be breeding for the betterment of the breed and as a matter of reputation would certainly never sell me an unhealthy pup. The dog has a ton of issues including luxating patellas, inverted tail that will probably have to be removed, and allergies so severe that she cannot really go outside without breaking out into hives. I should of had a clue when I saw the mom who hardly had any hair (a champion, mind you) and allowed the breeder to let me believe that it all fell out after she had the pups and was growing back....LOL
Of course when I brought all this up several months after the purchase, the breeder denies any knowledge that the pup had issues. I was offered to return the dog, but thats a great trick they play. Who would return a puppy that they have fallen in love with over several months without knowing what it's fate would be?? Anyway, in the 5 months that I have had her, I already spent $2K on her skin issues alone.
What I learned from the experience and used it to purchase my second, very healthy, bulldog from another breeder is this:
Educate yourself about all the problems that could plague poorly bred bulldogs and other signs of potential problems in a pup and make sure you see the puppy in person before you buy it. Do not buy over the internet.
For my second bulldog, I looked at his tail and made sure it was not inverted. I looked at his skin and made sure there were no breakouts or hair loss. I looked at his eyes and made sure the conjunctive tissue was not red and that the eyelids did not roll in or out. I looked at his nares to make sure they were not too tight. Opened his mouth and looked at his pallet to make sure it did not look elongated. I even checked his knees for luxation. I checked the ears for swelling and yeast. I learned that certain "rare" colors carry hereditary health issues. I learned all of this from internet research plus more that I am forgetting.
In my opinion, this is the best thing you can do when looking to buy a pup. Don't just count on the breeders ribbons. That's my two cents. Hope it helps!
