Thanks to their mixed genes, mutts are less likely to have received a high dose of any particular breed's genes. Because of this, many mutts have a lower rate of health conditions, such as hip dysplasia, spinal diseases, knee problems, certain cancers, heart disease, and more, than their purebred counterparts.

Are mutt dogs bad?

As a result, many mutts have a lower rate of hip dysplasia, certain knee diseases, most spinal diseases, many heart diseases, plenty of cancers and a whole lot of skin, blood, brain, liver and kidney diseases, among others. Statistically speaking, mixes win out — but genetics are only half the battle.

What is wrong with mixed breed dogs?

Genetic issues.

While many breeders argue that cross breeding produces healthier, stronger dogs, there is no scientific evidence to back this up. Therefore, the combination of two separate dogs could potentially lead to serious genetic entanglement issues; it could work out brilliantly, but also terribly.
