Well we always wish that people would ask us what to look for before they buy a dog as many times we have good solid information about breeders that are less than reputable and it's much easier to share that up front than after you have your baby in your lap.
You will also want to talk to your vet about HA because many commercial kennels kept breeding stock that had not been tested and were carriers.
So many people think us show kennels are just for show dogs and since I don't want to show I'll just get one from this back yard breeder or 'pet' breeder - when really the issues we care about are the dogs life.
Good luck with your baby I'm sure you will enjoy her.
