I went through your thread again and saw that early on you mentioned that the vet said Anika had bad breath. I think that you've mentioned a few times that her teeth are fine but I wonder if she might have an oral ulcer? If it was located under the tongue or at the back of the throat it might have been missed by the vet. That could account for the difficulty in swallowing and drooling and oral ulcers can cause bad breath. And could make it too painful to eat food.

Mouth ulcers can be from lots of different things including kidney problems. But I didn't read anything about the blood work showing anything regarding kidneys. I did find some stuff on the internet about liver disease and drooling.

And as a few other pt'rs mentioned, it could be nausea. Drooling can be caused by nausea. I don't think ulcers would cause vomiting but nausea sure might.

If your vet doesn't find any ulcers in Anika's mouth and if the ultrasound doesn't show anything new, maybe you could try an anti-nausea medicine and it might help her to be able to eat.

If the injections are stressful, maybe you could ask your vet about a single injection that last for two weeks called Convenia. It is in the amoxicillan family so it might be able to replace the daily amoxi shots you are giving. I don't know about the Baytril though.

I hope you will be able to get some fluids into her. Prayers going out for you and Anika.
