a dog that is scared of the tub?

so my precious dog is scared of the tub. Don't ask why, he just doesn't like it. He loves pools and garden hoses, but TUBS? nope. So today I decide to keep him inside the bathroom while I head to Laurels for a visit because he is way too big for the dog cage that we have. What do I come back to? A half eaten bar of soap and a hair covered tub. This wacko dog decides that he loves the tub after his hateful past relationship and sleeps in there for most of the morning. I think that I have found my solution to wanting to get rid of the black cage that ruins the decor of my usually spotless living room... well... minus the random toddler toys and raw hide.....
