The more breeding takes place within a closed gene pool (i.e. ![]() Genetic disorders occur when offspring inherit one mutated recessive gene from each of their parents. Any type of dog may be healthy or unhealthy.īut, without diving deep into the field of genetics, here’s the gist of the theory that purebred dogs may be more prone to certain disorders. Let’s clarify that just because a dog is purebred doesn’t mean it will have health issues. Why do purebred dogs have health problems? But many of the genetic disorders occurred equally among all dogs, without regard to purebred or mixed-breed lineage. Seeing that only 4% of these disorders were more prevalent in mixed-breeds, the findings indicate that you’ll have a better chance of avoiding health issues if you have a mixed breed dog. So are mixed-breed dogs healthier than purebreds? Yes, but only in certain areas. It was also found that mixed-breeds are more likely to be hit by a car. There was only one disorder that was more likely to occur in mixed-breeds than purebred dogs: Cranial cruciate ligament rupture. These purebred dog health issues include: The AKC states that “these studies have concluded that purebred dogs are no more prone to genetic disorders than are mix-breeds, and to suggest otherwise is misguided.” But when digging further into the UC Davis study, we find that there were 10 disorders (42%) that are more prevalent in purebred dogs compared to their counterparts. In a 2005 study on hip dysplasia, the results indicated there was no statistical significance in the prevalence of this disorder between purebred dogs and mixed-breeds, nor between sexes. However, the health discrepancy between the two categories of dogs may not be as big as was once thought.Ī 2013 UC Davis study of more than 27,000 dogs found that in more than half (54%) of the 24 genetic disorders tested, there was no difference between the two categories. The main theory is that mixed-breed dogs have a greater genetic diversity, which eliminates many health issues that stem from a closed gene pool. Over the years, a general consensus has formed that mutts tend to be healthier than purebreds. ![]() Of course, if your goal is to adopt instead of shopping, this is an inevitable but worthy risk. If you choose a mixed-breed puppy, it may be harder to determine the dog’s adult size, behavioral traits, or if the pet will fit your lifestyle. While not always true, this is especially the case if you choose a dog without knowing the parents’ breeds, such as a dog from a shelter. There are also popular breed mix combinations that are intentionally bred, such as the Goldendoodle (a Golden Retriever-Poodle mix).Īccording to the AKC, when you choose a mixed-breed dog, you lose some of the predictability you may have with a purebred. However, you can try to use a dog DNA test such as Embark’s Breed + Health Kit ( also available at Chewy) to determine your dog’s genetic history. In fact, many mutts are the result of unplanned contact between unsupervised pets. The exact lineage of many mutts is hard to distinguish since they aren’t typically bred in a controlled environment. This is why you’ll hear mutts also called mixed-breeds. What is a mutt?Ī mutt is simply a combination of two or more dog breeds. However, prices vary significantly from breed to breed. ![]() Since there are more criteria and certifications that go into breeding purebreds, they are usually more expensive. This allows for a level of predictability that some owners need.Ī few examples of purebred dogs are Yorkshire Terriers, Golden Retrievers, and German Shepherds. They are bred for distinguishing characteristics like physical traits, temperament, ability to complete certain tasks, or other genetic criteria. Purebred dogs are members of a single, institutionally recognized breed without any history of cross-breeding over many generations. ![]()
