Ugh, this is such a hard one. I'm very sorry you're going through this and can empathize because I've got a 13 year old dog who is going downhill too. I've gone through this three times now. Once with a young dog with leukemia and twice with older dogs. With the older dogs I did wait until it was clear they were ready to go. I had a very hard time deciding what to do with my first dog because she went downhill over a long period. When she stopped eating I knew it was time. Same with my Basu.
Have you tried a harness for your dog? That could really help with mobility. I know some people whose dogs have DM also use a cart for them. Check out this website: http://www.handicappedpets.com/prodwalk.htm
