Her Dog Stinks Up The Apartment

We've been roommates for the better part of 2 years and Caitlin just got a dog about a month ago. She's so in love with it which is great, but she doesn't ever consider the fact that the thing pees everywhere when we're at work and she's made no effort to have him trained or do it herself.

Sometimes we'll go days before we see where the smell is coming home.

Don't get me wrong. I love living with Caitlin and we don't fight often, but her lack of considering how I felt about the dog (forgot to say she never asked if it would be ok since she thought she would keep it in her room) and the fact it's making the carpet stink is making me mad.
