Chuck the pug

Three weeks ago, Chuck started acting strangely. He was disoriented and seemed to have lost his balance. When I brought him inside, he laid down and his head was at a strange angle and his eyes were moving back and forth. He got stiff. I picked him up and put him in the car and went to find a vet. Prior to this, we suspected he had diabetes because of the amount of water he was drinking and the rivers of pee. The vet's diagnosis was that yes, he had diabetes, and also old-age encephalitis, and maybe a low thyroid. He gave him insulin and a B vitamin shot and put castor oil in his dry eyes and gave us meds for the encephalitis. Duane is also diabetic and it turns out his insulin is the same kind that Chuck needs, so we are set there. Chuck is much better now. However, the RV has a nasty urine odor. I have to get some enzyme cleaner for this. I am hoping to train him to pee in the shower. So far, no success. Getting up several times a night to take him out is torture.
