Janet I had been with my clients more times than I care to remember and 2 times myself. It is never easy to know when the time is right. Deafness and blindness is so common in our older guys. I believe a dog that is eating well, not vomiting or have diarrhea, breathing ok, can get up on there own(even if it is somewhat slow),and wants to be with their family still has good quality of life regardless of the medical issues they face. Of course, owners who are in touch with their dog as you are, I always have faith they will make the decision when it is best. As long as we always put their needs above our own,we can't go wrong. I hope Indy has many more health months/years ahead.
