Health
Several studies have shown that mixed-breed dogs have a health advantage over purebred dogs. A German study finds that "mongrels require less veterinary treatment". Studies in Sweden have found that "Mongrel dogs are less prone to many diseases than the average purebred dog" and, when referring to death rates, that "mongrels were consistently in the low risk category". Data from Denmark also suggest that mixed breeds have greater longevity on average compared to purebreds. A British study showed similar results, but a few breeds (notably Jack Russell Terriers, Miniature Poodles and Whippets) lived longer than mixed breeds.
