However, now that the competition is officially opened to mixed breeds to compete alongside their purebred cousins, "The Early Show" celebrated these magnificent mutts by showcasing them in their own "beauty pageant."
"Early Show" Resident Veterinarian Dr. Debbye Turner Bell explained there are some advantages to having a mixed-breed dog.
She said, "There's something called hybrid vigor in genetics, meaning in general most mixed breeds are healthier, have fewer breed-related diseases, and live longer. A lot of purebred have not been bred responsibly, so negative health traits get propagated down the line across generations. Mixing with another breed dilutes that. Some fans of mixed breeds will also say they are smarter and easier to train. If the principal is true for genetics, then it may be true as well for this."
As for disadvantages, Bell says owners don't know what they're going to get in terms of size and appearance. Also, a lot of people get caught up in the high premium placed on pedigree and want purebred and designer mutts.
She said, "You might lose a little status in your social dog park."
If you're looking to adopt a mixed-breed puppy, Bell said it's a myth that you can gauge the dog's eventual size.
"There is no way to know their size," she said. "Even if their coat is all white when they are a puppy, for example, they may develop spots or something later. You have to like surprises! You really don't know what you're going to get until you get it!"
The most popular mixed breed is the poodle. Bell said poodles are popular because of low shed, they are hypo-allergenic, and they have great temperaments and are easy to train.
"Otherwise, it's just a matter of what dog got out of the yard that day," she said. "For your garden-variety mutt, what's popular is often whatever the popular purebreds are. Labrador, golden retriever, and yorkies are all popular. Some don't get spayed or neutered, and when they get out, mixed breeds are made!"
However, if you really want to know what your dog is made of, Bell said you can have genetic tests conducted to discern its origins. She suggested the Canine Heritage Breed Test, which costs $75. Also, Wisdom Panel TM MX Mixed Breed Analysis Test is available.
