Diesel is the never ending drinker. He drinks EVERY bit of water available until it is gone. Bowls, puddles, side of the shower, sliding glass door in the rain. Therefore we are having difficulty teaching him to ONLY go pee outside, but he is much better. Bathroom doors must be kept shut as the toilet, shower and sink are all fair game for Diesel. No dirty dish can be left in the sink, he will lick up each and every drop of water. I can only water plants when he is outside, he will lick the water out of the dirt before it is absorbed. My little water boy!!!
