I don’t know how much longer Pax will be with us.  Last night the dog came in and walked to the kitchen.  He was on his haunches and his hind legs were so weak that he could not get up right away.  He has two torn knees and get pain meds twice a day.  Our vet said on his last visit just make him as comfortable as you can.  There is no more he can do for him.  Pax is thirteen and an half–pretty old for a large dog.  The time will come when we will have to put him down.  Right now I will enjoy him as long as I can.  He won’t be around much longer.
