Purebreds are looked at by society as being the top of the line, best of the best dogs. While in actuality, they are easily the worst dogs to have. Why is this? Let me be clear, it’s not the dogs fault, how could it be? The Honest facts are that Purebreds are inbred, this lack of biodiversity causes these dogs to develop more physical problems than any mixed blood. If you want a healthy, happy dog, get a dog with a couple different breeds in it, it’ll have a better chance of living longer, and less physical defects.
