1. Shar Pei

Sadly, Shar Pei dogs are one of the breeds of dogs most prone to disease. The Shar Pei tends to suffer from many skin diseases. This is due to their characteristic folds which promote bacterial growth. They also produce more sebum than many other breeds which encourages skin problems. They are also prone to other canine disorders, such as entropion, hip dysplasia, cataracts, hypothyroidism or megaesophagus.

Although it is not well known, the Shar Pei is partly known as one of the most unhealthy dog breeds because they have a disease named after them. This is known as Shar Pei fever and it can cause inflammation, gastrointestinal disease and other disorders.

Purebred vs. mixed-breed dogs

It is important to note that there are no breeds of dogs that are 100% healthy and are immune to becoming ill. However, it is true that purebred dogs generally tend to suffer more from hereditary health problems than mixed-dog breeds.

You may wonder why are mutts supposedly healthier than purebred dog breeds. The dog breeds that meet breed standards have been bred in such a way that their genetic lineage is limited. This is because breeders want to encourage certain physical or behavioral traits which are also controlled by genetics. By encouraging these traits, they also propagate the genes which are associated with hereditary disease.

For some dog guardians, they consider many of these most unhealthy dog breeds to be dog breeds that shouldn't exist. They consider the propagation of certain traits to be irresponsible and the desire for a uniform breed is immoral. When we add to the fact that many lay persons try to breed dogs and do so in ignorance or in lacking responsibility, it does present a problem.

This does not mean many purebred dogs cannot live long and happy lives. But the fact that we can pinpoint these unhealthiest dog breeds means we may need to reconsider how we breed companion animals. Share your thoughts in the comments.

There are also some breeds which are thought to be healthier than others, as you can see with our video below on the longest living dog breeds:

Breeding any animal for particular characteristics guarantees there will be medical problems. It is animal cruelty.
