When I lost my 4 year old EB to heart failure, I said "NEVER AGAIN". But that nagging feeling that you're missing something --- and something might be missing you --- returned and, like you, months of research and referrals up the yang and little Bea came home. She's three now. Bo followed a year later; a puppy from rescue. Everyday I acknowledge how lucky I feel and how empty and meaningless my life would be without these two messing it up all the time.
Welcome. Thank you for doing your research. Choosing a breeder is THE MOST important thing to consider when adding a puppy to your family. Those breeders that breed for health and temperament --- and an obvious love of the breed ---- help you start your journey with the best possible outcome in mind; a happy healthy bully for many many years.
