In-laws dog peed on my brand new couch!!!

Long story short. My in-laws are living with me and my husband while they get their house remodeled. Their 9 year old dog is poorly house trained and has peed all over our carpets the past 2 months. Thankfully we have a Bissle cleaner. Well tonight, he peed on our brand new linen sofa. Then decided to walk the entire length of it and take the urine with him. My husband was more upset than I was! So freaking annoying. I guess god is preparing me for kids.
