[SANDY DOBBELS]

I have had my english bulldog since the end of September of 09. He was on a great schedule until I went out of town and left him for 4 days with my brother-n-law. When we came home and later that night Ozzy was up every 2 hours. And since then he is up every 11/2 to 2 hours every night for almost 2 months now.. I need help!! I took him in to the vet and he had worms and the vet thought that might be what was keeping him up at night. But days,weeks went by and no change. So I called the vet again and told him no change. He thought maybe he has a kidney infection since he goes potty every hour or 2.So got him antibotics and again no change. He is perfect during the day ,crate trained . But at night if I ignore his barking he will poop and urinate in his crate every time.This is getting out of hand NO SLEEP WILL DRIVE A PERSON BATTy... I really love this dog and would like to keep in and figure out what is going on with him... HELP ME please.
