History of Selective Breeding in Dogs
Most, if not all, breeds of household dogs that exist today are due to selective breeding in dogs. The original bloodline is that of the gray wolf, some 18,800 – 32,100 years ago and may have since died out.
However, as purebred dogs are becoming increasingly inbred, problems are arising from a genetic standpoint. Selective breeding in dogs increases the risk of rare recessive disorders, potentially causing severe health problems down the road.

One of the better examples of this would be the modern-day pug. Most pugs have severely deformed snouts, contributing to breathing problems. Selective breeding continues and we now have everything from Mastiffs to Poodles.
