Determining the Heritage of Your Mixed-Breed Dog
The best way to figure out the breeds that make up your mixed-breed dog is to look through an encyclopedia of purebred dogs. (A mixed-breed dog is one who has been conceived by two different purebred or mixed-breed dogs. The parentage of many mixed-breed dogs is unknown, because the breeding wasn't planned. Two unsterilized dogs crossed paths when the female was in heat, and the rest is history.)
Most mixed breeds have some appearance or personality that resembles one of the parent breeds. Often, you just have to look at color, coat type, or size to have a vague idea of which section to look in. For example, if the dog is large, has a beauty mark on the cheek, and has upright ears, there's a good chance he's part Shepherd. If the dog is small, with long silky fur and a short nose, there's a good chance she's part of some Toy dog breed, likely some Pekingese.
Make a list of your dog's attributes. Compare them to those you see in the encyclopedia of purebred dogs where you can find an overview of the different breed groups. When you have a fairly good idea of your mixed-breed dog's genetics, read more about those breeds to learn about their behavior, temperament, and health-related issues. Doing so will help you know your dog even better than you already do!
Even though you have no idea what your mixed-breed puppy will grow up to look like, there are ways to be sure he'll still be a good pet. Your good care, training, and love will make him the ideal companion. It doesn't matter what others might think when they see your short-legged, long-backed, droopy-eared, multicolored dog with the overshot jaw and wrinkled forehead. All that matters is your love and devotion to him, which he'll return tenfold.
