Hubby and I don't celebrate x-mas, but my in laws do. One year when we were there, Drake decided to lift his leg and water the tree! Luckily I saw him right as he was starting and Andrew got him outside! He's never peed inside since he was very lil pup, but somehow he thought it would be OK since it was a tree!!

He has been around several other xmas trees since then, but hasn't tried to pee on them!
