I don't know anything factual as I haven't done any research on this... however, I have definitely found in my experience with family and friends who own mutts and have no idea what they are mixed with... have zero to very little health problems. Sheer luck? I don't know. But my uncle owns a mutt who went to the vet for the first time in like 4 years a few weeks ago. She's 13 years old right now, a large mixed breed, and perfectly healthy besides a little pain in her joints. My friend owns a 17 year old Black Lab looking mutt. My step-dad owned a total unknown mutt named Judy for 18 years, towards the last year of her life she began becoming blind and deaf but 18 years! Among many others. So... who knows. |
