What should we do?

Question
We have a 1 yr old mini pin named Rocky.  At the end of April, Rocky started vomiting, diarhea, stopped eating and drinking.  We took her to the vet and they put her on an IV.  We picked her up that same day and took her home.  She just laid around and was not herself.  We took her back to the vet the next day, they put her back on IV, and we picked her up on the 4th day.  She still was not eating, and was vomiting minimally because of lack of food.  We kept her home for another night, but there was no improvement in her condition.  We took her back to the vet, and they did xrays to see if there was a blockage.  The xrays did not show a blockage, but there were some spots that were questionable, and two of the Drs. recommended exploratory surgery to confirm there wasn't a small blockage.  Rocky was famous for eating everything in sight.  (Two weeks prior, she brought a dead baby bird into the house.)  When they opened her up, they said the stomach and intestines were very swollen and irritated, but there was no blockage.  They said they cleaned up the areas and closed her up.  After the surgery, Rocky had signs of ataxia.  Approximately on the second day, the Drs. started force-feeding Rocky, and she was able to keep the food down.  Since the surgery, Rocky has experienced tremors, and is extremely unstable.  Her mind is fine, but she shakes, and walks like she is drunk.  She appears to be very weak, and has lost control of her legs, paws, and ability to function normally.  We hand feed her because she is not able to stand in front of the dish to eat.  She does not appear to be in any pain, and tries to act like herself, but can not control her movements.  My husband and I are considering putting her to sleep, but we love her too much, and want her to be herself again.  What should we do?  Thank you.  Susan Theriault

Answer
I would recommend an ultrasound of her abdomen to check her liver to look for a shunt.  Also, check with your vet to see if they checked electrolytes to rule out Addison's disease.  The other consideration is going to a veterinary neurologist for specialty tests of the nervous system.
