I am by no means an expert and we do not even have our pup yet, but he will be here Saturday. This is also my first bulldog though I have wanted one since I was 10 and now I am 40. I googled bulldogs for sale and the three states that surround me. I was trying to limit my drive to 4 hours or less but I would have driven 6 hours if I had too. I went to their websites etc. I was looking for puppy mills and trying to avoid those. One thing I looked for was if mom and dad were in the house or a kennel. I prefer house. I looked to see if the breeders had kids. Ultimately for me, I spoke to them on the phone and via email and text. I got a good idea pretty quick which breeders I trusted more. I wound up picking a breeder about an hour away that has only been breeding bulldogs for a couple of years but seemed really knowledgeable and caring. She is trying hard to build a business and she was as picky as I was about who she was going to sell hers to. When we visited them at their home we could tell her bulldogs were well taken care of. She seems really honest and my wife and I felt like we knew her and her husband for years. We stayed at their home for 2 hours. She guarantees her pups for one year, which most do. I would recommend just asking a lot of questions and you will get a feel for who you trust. There were three that I spoke with that just didn't feel right. One was only 30 mins down the road but she wouldn't let us come and see her pups for a week or two she said and they were six weeks old. That made no sense to me. Also, the breeder we chose sent the most pictures and videos when I requested. She sent a ton of information and pictures. That was another key to me as a few breeders would send one picture and it would be a closeup of the face.
