Question
We have a 20 year old pomeranian named Pompeii.  He has arthitis and we have pain meds for him when he has severe attacks.  He also has compromised kidney function - he was diagnosed with low function over a year ago.  Whith all of this he is still a relatively healthy, but happy and content dog.  Today we took him to the vet because he would not bear any weight on his right hind leg.  The vet told us he dislocated his hip, and that she has never seen a displacement like the one Pompeii has.  Instead of dislocating out and upward, it has moved out and back.  When they did the x-ray she also found that he has kidney stones (which confirms the low kidney function).  She has told us that we basically have three options - a manual adjustment, a surgical procedure to repair the dislocation, or euthenasia.  She is concerned that because of Pompeii's age and health he would not heal or potentially not make it through the anesthesia.  She also said that we could just let him be since he does not seem to be in pain.  Her strong recommendation is euthenasia, but we are not sure.  We want to make sure that there is nothing else that can be done.  Is there a diet for animals with low kidney function to stop or reverse the muscle deterioration that Pompeii has?  Can we feed him double or more his usual food to counter the loss of protein from the low kidney function?  He has also lost 3 pounds in the last year and a half.  We also wanted to know if all of these health problems signal the end is near - and if so should we just leave him alone and make him as happy and comfortable for the last 3,6 or 9 months of his life.  We have had him for 10 years, we adopted him from a shelter and he has been a wonderful and faithful loving friend for many many years.  We want to do the right thing - we owe him that much and much more.  Any help you could offer would be very appreciated.
