Mars Veterinary has conducted a national mutt census for mixed-breed dogs.

Mars is considered the leading authority in dog DNA analysis.

Mixed-breed dogs account for 53 percent of all pet dogs in the United States.

Mars said the most common DNA found in those mutts is that of a German Shepherd.

Other common mutt breeds include the Labrador Retriever, Chow Chow, Boxer, Rottweiler, Poodle, Terrier, Golden Retriever, Cocker Spaniel, and Siberian Husky.
