This means that nearly every breed of purebred dog has chronic health problems that never get fixed. ... They found that purebreds were more likely than mutts to have any of 10 different genetic ...
The study—which surveyed the owners of more than 27,000 companion dogs—also found that some of the most common diagnoses, like ear infections or osteoarthritis, occur in both purebreds and ...
A new study finally answers whether mixed-breed dogs are healthier than purebreds, and now that whole question has been settled. According to new research from the Royal Veterinary College, the ...
The theory of hybrid vigor suggests that as a group, dogs of varied ancestry will be generally healthier than their purebred counterparts. In purebred dogs, intentionally breeding dogs of very similar appearance over several generations produces animals that carry many of the same alleles, some of which are detrimental. If the founding ...
