Do you think a breeder can responsibly and effectively "specialize" in more than one breed of dog? When I was searching for a breeder I ran across one who bred both Malinois and GSDs. I didn't look twice at them because I wanted a breeder who was super knowledgeable about the breed I'd chosen. I have no regrets because I found a great pup. I wonder if I was wrong in my judgement. What do you think?
