Hello, I'm looking for advice. We are about to buy a labradoodle. There is a litter that we like a lot but the trouble is that mum who is a Labrador and the family pet had not had her hips screened or eyes tested. The owners later sent a text to say they can't get hold of her breeders for more information and that they will be happy for a refund if we decide to take one pup home and aren't happy with anything. Should we go ahead and buy one?
