premise: He is 10 months old and is testing us big time . By that I mean he is going the bathroom in the house and here is the thing , when my brother comes to visit he sleeps on the couch in the living room where the dog stays while he is visiting the dog is a peach . He does n't chew stuff up or go the bathroom inside . It 's not like he is n't out enough either , my daughter takes him out about every hour and a half to go the bathroom . Why is the dog going to the bathroom in the house ?
hypothesis: Because the dog does n't chew stuff up .
