Johanna, ask your vet to inject B12 or even all the B vitamins into the subQ bag. S/he may say that it won't help, my vet said so too, but it brought Puddy back. She ate, she had energy, her senility left, all of it instantly. Because Allie is so thin, it would be better to inject the B's right into the port on the bag instead of the skin b/c it does burn but this way Allie won't feel it. It couldn't hurt but I'll bet it'll help big time.
