...And thank you for the suggestions for Bosco. Unfortunately, his condition is such that it is just a matter of time until, well, it is time. He has Cushing's Disease (which is basically a tumor) and the only other option is surgery, which I do not plan on doing. Bosco is probably around 11 or 12 years old, so there is no sense in doing anything drastic. I love him with every fiber of my being and he has been the absolute best dog, ever. I could not have ever imagined getting such a well tempered, friendly, easy going, well behaved dog.
He does not seem to be in any pain, and I do not know that he has arthritis, but maybe we will take a trip to the vet this week just to rule it out. He does take a pill that helps him not leak.
His appetite seems OK, although some days he only eats one meal but he does drink a HUGE amount of water and he sleeps a lot and doesn't move around a lot. He is just old and tired and I am sure the tumor is taking it's toll on his body.
