Mongrels cost less to adopt than purchasing a purebred from a groomer. Estimates place the prevalence of mongrels at 150 million animals worldwide.
Mongrels can have a very individual and cute appearance based on the mix of different traits from the various breeds included in their makeup. Mongrels are often less prone to some health concerns since there isn’t as much inbreeding as you find with purebreds.
National Mutt's Day, also known as National Mixed Breed Dog Day, was created in 2005 by Celebrity Pet & Family Lifestyle Expert and Animal Welfare Advocate, Colleen Paige and is celebrated on both July 31st and December 2nd.
