What a beautiful dog. I have a rat terrier that has diabetes and has gone blind. I have to give him insulin 2 times a day. I searched on the internet and there was a wonderful support group out there with dogs that had the same thing. I got wonderful advice and help through some had times. I do agree if you are not happy with what you vet has told you it would not hurt for a second opinion. Wishing you and your furbaby many more years together.
