They die like flies and breed like rabbits, that’s how they get along.
We put down my 17 yo yorkie poo a few years ago and he had never been to a vet. Ever. His rabies shots came through the yearly rabies clinic. I can count on ONE hand the times we’ve taken ours to a vet through out the years and that includes the Great Danes, the heelers, the English Mastiff and our three yorkies.
