Big Paws Only Dog Forums

My 13 yr old big boy has been having recurring problems with getting up and down. For a few days he will be almost immobile then he will come out of it in just a couple days. I'm concerned that his quality of life is dwindling. He has been with me through thick and thin and my heart breaks to even think about having him put down due to poor  quality of life. Does anyone have suggestions. I'm having to move out of the country soon and am concerned that he won't make the trip.
