I'm asking these questions because, in a few years (closer to 4 or 5) I'm looking into breeding dogs. Not for the cute puppies, or to overpopulate the puppy mills and shelters with puppies, but to try to breed them for optimum health, intelligence, affection, size, perfect show-quality, etc. This is interesting to me as I'm working on biology at the moment, and want to look into genes. Seeing as there are a lot of dog owners here, I thought it would be a good idea to ask a few questions about your favourite breeds and why. Also, it would be helpful to tell me about the optimal diet, excercise, mental stimulation and grooming so that I can make each and every dog that I own in the future very healthy. Once again, if/when I decide to do this big task, I will not give them away to anyone put good homes, and never to shelters. Thank you, everyone!
