I know how you feel. My Brody had a lot of health problems but I did my research and learned from it. It was really tough seeing him go through so much. The website you linked is full of red flags that other members touched on so I'd stay away from them. Ytca.org is a great place to start. Rescue is always an option as well. There are a few sticky's on the site about what to look for and beware of in a breeder. Just research, research, research. It's a long process but just be patient and you'll find a happy, healthy baby
