Humans have relied on dogs for thousands of years. Not every dog is as healthy as they should be due to our interference. Over the past few centuries, human-guided breeding has split dogs into hundreds of different types. These characteristics can lead to a high risk of health problems if they are inbred.

Scientists, animal welfare advocates, and some breeders have been trying to bring attention to the plight of the less healthy dogs. Some countries have recently taken action to heavily regulate or effectively ban the breeding of certain dogs due to the fact that there are many in these communities who believe that it is still possible to steer breeding practices in a positive direction. The buying and selling of specific breeds has been discouraged by some organizations.
