When it comes to buying a dog, you select either a pure breed or a mixed breed. Pure breeds contain a unique genetic makeup, which can be reproduced consistently. Any dog resulting from parents of the same breed is a pure breed. The main benefits of choosing a pure breed are predictability and consistency. On the other hand, a mixed breed is obtained from two parents of different breeds. Mixed breeds also have their advantages. First, you get a pet that combines two different breeds. Additionally, your pet will also be less prone to certain genetic defects associated with certain breeds.
