Oh and everything 25 said is worth listening to!! I also had a similar situation with an animal who seemed paralyzed. He went ahead to live a healthy life with some treatment. I have a great vet who has been there for us in many ways through the years.
Definitely if you have to put him down, the whole family is the way to go. He has been there for you guys and given unconditional love. It's the least we can do for our friends as they pass on.... *i tear up when i write about this type of thing!* you are in my thoughts as always man.
