I dont wipe, if they have poo on them I give them a bath. But normally they have clean poops and no straglers. I do however get to wash Khloe often because she gets pee all over the inside of her legs, I have her trimmed up very good and she still manages to get pee all over her. So about every other day she gets a bath
She also rolls in the dirt outside so she needs one that often anyway..
