Well Things are still iffy

I'm not exactly sure if its the heat , poor air quality,his age, the amputation...but Beebs seems depressed. Last week he seemed more lively and now something seems weird to me.I'm on top of the pain meds and do everything to keep him comfortable and relaxed.Phew...i just hope he gets a few good years to enjoy life again. The other back leg is not holding up very well which I suspected would happen because of the arthritus in there which is big and knobby.I just want him to be happy.
