are generally healthier than purebred dogs. This is because purebred dogs have a limited gene pool and risk passing along genetic disorders from generation to generation. Typically, owners of mixed-breed pets can expect to pay a lower pet insurance premium than owners of purebred pets.
The study also discovered that fewer mixed-breed dogs than purebred dogs are affected by the disease-causing mutations tested, identifying genetic diseases that mixed-breed dogs are likely to develop.
“Frequency and distribution of 152 genetic disease variants in over 100,000 mixed breed and purebred dogs” was published on April 30 in PLOS Genetics, an online journal of the Public Library of Science, by Wisdom Health and Genoscoper Laboratories, which provide genetic tests for dogs and cats.
The study looked at the DNA of 18,000 purebred dogs and 83,000 mixed-breed dogs from 330 different breeds, types, and varieties. Tested disease mutations included those for von Willebrand’s disease, hyperuricosuria, Collie eye anomaly, and progressive retinal atrophy.
There has long been a belief that mixed-breed dogs are less likely to contract diseases than purebred dogs, according to Dr. In a statement about the study, Wisdom Health’s general manager Cindy Cole “While mixed-breed dogs are actually less likely than purebreds to develop the recessive disorders evaluated in the study, they may still be carriers, according to DNA testing-based evidence. “.
Based on 152 diseases tested, 40 out of 100 mixed-breed dogs were carriers for at least one disease, putting two out of every 100 dogs at risk of developing it. 28 out of 100 purebred dogs had at least one of the diseases, and approximately five out of every 100 were carriers.
The research also showed that some diseases appeared to have been eliminated from breed pools through healthy breeding practices, which frequently include genetic testing. For instance, it appears that X-linked severe combined immunodeficiency, a mutation first discovered in Basset Hounds, has been eliminated.
Both purebred and mixed-breed dog populations in the study had the most frequently affected ocular, nervous, and circulatory systems.

I’ve worked as a veterinarian at one of the biggest veterinary emergency hospitals in the nation for more than 30 years. More than 11,000 cats and dogs are treated at our hospital’s emergency room each year. Thousands more see our veterinary specialists. I’ve taken care of a lot of dogs, as you might imagine, so I’ve probably seen just about every type of canine illness you can think of. In addition, I’ve owned and bred Afghan Hounds for a very long time. One thing I’ve discovered through my experience is that virtually any dog can become ill. However, my extensive personal experience and a significant study carried out by the University of California-Davis show that mixed-breed dogs are not healthier than purebred dogs.
The study was published on June 1, 2013 in the Journal of the American Veterinary Medical Association under the title “Prevalence of inherited disorders among mixed-breed and purebred dogs: 27,254 cases (1995-2010)”. To ascertain the likelihood of occurrence of 24 of the most prevalent hereditary diseases in dogs, researchers used more than 27,000 patient cases. This thorough investigation disproves articles that assert purebred dogs have a higher prevalence of hereditary diseases.
Researchers discovered that, when purebred and mixed-breed dogs were matched for age, sex, and body weight, “13 of the 24 disorders assessed had no significant difference in the mean proportion of dogs with the disorder.” “Although no one breed was predominately affected by any one illness, one disorder was more common in mixed-breed dogs and the other 10 were more common in purebred dogs. Numerous conditions that are frequently linked to a particular breed, such as lymphoma, mast cell tumors, particular cardiac conditions, hip dysplasia, and lens luxation, are just as likely to affect mixed-breed dogs.
This makes sense given that only a small number of wolf lines are thought to have produced the majority of domesticated dog breeds. Thus, all dogs have strong genetic tendencies that include some health-related traits. National breed organizations for purebred dogs, including the American Kennel Club Canine Health Foundation and the Golden Retriever Club of America, have collaborated to identify breeds with a higher risk of particular health issues and to take precautions to reduce the risk. To improve the health and wellbeing of dogs, the Canine Health Foundation has actually invested more than $35 million in research.

Purebred vs. Designer Dog vs. Mixed Breed
You’ve probably heard the terms purebred, designer, or mixed dog mentioned in conversation when discussing a dog’s breed, ancestry, or genetic makeup, but what do these terms actually mean?
A purebred dog is one that has a proven pedigree and can typically be easily tracked back in time. Dogs of the same breed are always mated with another canine of the same breed when it comes to purebreds. Additionally, there are established, predictable breed standards for these dogs’ appearance, wellbeing, and temperament.
If you choose to adopt a purebred Golden Retriever, for example, this indicates that both of your dog’s parents are Goldens and that their parents were Goldens as well. This also means that since your new dog is a Golden, you can easily look at other dogs of this breed and make an educated guess as to what your dog will look like and how he or she will act without ever having met the dog.
Designated dogs are those with two purebred parents of various breeds. Over the past few decades, these purposefully bred dogs have grown in popularity. Despite having purebred parents, the puppies are not considered purebred due to the lack of breed standards or consistency from generation to generation.
There is no such thing as a “purebred designer dog” even though a designer dog may occasionally have two of the same designer dog parents and their offspring are still not considered purebred. “For instance, a Goldendoodle could have two Doodle parents or a Poodle parent and a Golden Retriever parent.
Poodle mixes are one of the most widely seen breeds of dogs in the designer category. You may have heard of Goldendoodles, Labradoodles, Maltipoos, Puggles, Yorkipoos, Chiweenies, and Pomskies among other popular designer dogs.
Dogs of mixed breeds are frequently the outcome of nature taking its course. There are countless breed combinations, and a dog’s history frequently includes so many different breeds. They are simply incapable of having any kind of breed. Dogs that are mixed breeds can be any size, shape, color, or pattern. Unfortunately, a significant number of dogs in this category wind up in shelters, humane societies, and rescues.
So this is all very interesting, but why is it relevant?
Due to their strong dominance, dominant traits are typically more prevalent than recessive traits. However, when a small population breeds together, recessive genes are more frequently passed on to offspring. As a result, more and more children are born who carry both recessive genes, enabling them to express the recessive trait. Some recessive genes are quite harmful and can cause genetic deformities, although many of them are harmless, like the gene for green eyes. If two people with the recessive cystic fibrosis gene have children, there is a chance that their child will inherit both cystic fibrosis genes and develop the disease. An example of such a disease is cystic fibrosis. Cystic fibrosis would probably be much more prevalent than in the general population if a small group of people who carried the cystic fibrosis gene kept breeding with one another.
This is the reason why (apart from moral reasons of course), inbreeding in humans is generally frowned upon. It increases the risk of producing children with nasty genetic diseases. Just ask Icelanders who have an app to check if a potential partner might be related, due to their small population! Yet we seem to have no qualms about doing this with dogs. In fact, we laud it and call them purebred or pedigree…
FAQ
Are mixed breed dogs really healthier?
Despite the fact that each dog’s health is unique to them, many people have found over time that mixed-breed dogs are frequently healthier than purebred dogs. Due to the small gene pool in purebred dogs, genetic disorders that develop are passed down from generation to generation.
Do crossbreed dogs have more problems?
The bottom line is that although purebred dogs do have a higher incidence of some inherited disorders, they are not more likely than mixed-breed dogs to experience many serious health issues, such as cancer, heart problems, and endocrine disorders.
