Is it true that purebred dogs need more medical attention than mixed breeds? Why?
vet-and-wild here.
Not necessarily. We know that certain breeds are prone to certain diseases, and that some breeds are generally just not very healthy (i.e. brachycephalic breeds), and some are frequently overbred with no regard for health/temperament (i.e. Frenchies, doodles, GSDs...really anything popular). There's some breeds that when I see for their first puppy visit I really really push for them to get pet insurance on principle. But if someone walked in and said they had a mix of those particular breeds I would still say the same thing.
There's kind of a misunderstanding about crossbreeding and "hybrid vigor", and this assumption that crossbreeding automatically makes the resulting puppies healthier. While genetic diversity is a good thing for a population, breeding two unhealthy dogs just produces more unhealthy dogs, regardless of breed or how much they've been crossbred. I wouldn't say that I see more sick purebreds than mixed breeds, or that one particular group seems to outlive the others.
Except really old chihuahuas with no teeth and a raging heart murmur. They outlive everyone. (jk jk)
