To Villas about dogs that are mutts versus purebred. I have purebred dogs they lived to 16, you have to get them from a reputable owner. Also some breeds are know to have hip problems, etc. . I have a purebred right now, met the breeders, who raised these puppies perfectly. We also wanted a small dog, and this dog is so sweet, no health problems at all, I would do it all over again. You have to do some research, read up on what breeds have health issues.
