My dog Tash suddenly went blind and deaf four weeks ago. He's 18 years old, a poodle mutt, in good health. He's had cataracts for many years, but was able to move everywhere, run and play with my other dog, and never bump into things. A month ago I left him inside the car for two hours, when I went back to the car and took him for a walk he appeared disoriented, began bumping into things and wouldn't respond when called. He's been like this ever since. His sense of smell doesn´t appear to be working well either. Tash often bumps into my legs. I would think even if he´s blind he would recognize me by smell. He walks all the time and doesn't stop wondering around. I took Tash to the vet, they took an x-ray and found a broken spinal disk on his neck. The vet said the disk had been broken for many years, and that maybe when my daughter's dog attacked my dog a week earlier could have bitten him in the neck and trigger the blindness and deafness a week later. Is that possible? My vet recommended acupuncture but says probably he won´t recover sight or hearing. Then last week Tash began to lose weight, sleep all the time, be very hungry but eat little, vomit often and to urinate and drink a lot. Yesterday he was diagnosed with diabetes and is hospitalized right now. Could these two problems be related? For how long could he have had diabetes? Any suggestions?
