Are cross-bred dogs healthier than purebred dogs?
The science tells us that dogs that are the result of matings between unrelated animals have a fitness advantage due to their genetic diversity, they are more resistant to both infectious and genetic disease. Perhaps the best indicator that mixed breeds are generally healthier is that it’s more expensive to purchase pet insurance for a purebred dog, because the average vet bills for pedigree breeds are much higher than for crossbreeds.
