I feel your pain. Expenses aside, I'm not looking forward to what I suspect is coming down the road, her ribs appear to be pushing outward like the last dog. Lots of snacks and love until her quality of life isn't worth it. Then, as grotesque as it might sound, bullet to the back of the skull to end it. I did the vet put you to sleep shot once before. Never again will I hold my dog down on a steel cold table in a strange environment while she is given a shot.
