Yes they do, and perhaps in past millenia, it was the survival of the fittest that knocked them out. These days however, they simply survive because of us humans.Originally Posted by lunasmom
I have a Cavalier King Charles Spaniel....great dog....lots of problems. I even knew that before I bought her. those dogs are notorious for spinal problems and respiratory problems, but I knew that....and live with that.
Perhaps that particular designer breed (being only a handful of centuries old) could never survive ourtside the domestic home.
