That heroic dog is missing a lot more than just ‘a paw’. If I’m seeing the form correctly, she is missing both right legs, fore and aft. Unless he is able to get a prosthesis for her to enable walking, I wonder about her quality of life in this condition. Is he really doing her a favor?
I know the owner’s love is there. I used to have dogs and cats. The hardest thing to do was to give them up from time to time, or learn to do without them after a natural death.
