I immediately think that it isn't right to do that to a dog and that it should have been pts, but then, if I was in that situation what would I do? What does the dog do when it isn't in harness though, just lie there, drag itself around, are they continent? In most photos though, the dogs look remarkably cheerful.
poor little thing! there is a dog up the road who got hit my a car a few yrs ago and had to have its back legs amputated his owner built him a little cart as he couldnt face putting him to sleep. he is so happy in it wags his tail plays fetch goes for walks etc and on a night he snuggles up with him on his lap and removes the cart and carries him with him xx
he has a good quality of life
owner has said when he gets old or in pain and cant walk properly anymore he will know it is time, but until then he makes his dog as comfortable as poss and he is very happy (always waggy tails) xx
no excuse for s**ty breeding feel so sorry for the poor over bred minis xx
