I'm going to refuse to take the dog to the bathroom
Why would you deny your dog the chance to go to the bathroom?
I hate dogs and I don't want to take care of her
Getting a dog means taking responsibility for their care no matter what. You making your dog hold it's bowels by not taking it for a walk to relieve itself is irresponsible. Take your dog out on a regular basis.
Nah I'm not going to do that.
Why would you get a pet if you aren't going to take care of it? It's just cruel to make it hold it's bowels. You really ought to take the dog out.
