thank you for your tips . I only want the best for him and I hope that the vet can diagnose and or fix that problem. It's just crazy - i have owned him since he was a baby back in 99 with no problems whatsoever. Now suddenly things have changed. I hope I can provide him another 20+ healthy years.

Also what bedding do you suggest? He always knocks the carefresh into the water bowl and makes a mess as of now. I would like to just use house carpet....cutting a new piece with each cleaning....would this be ok?
