House REEKS of dog

Pleeease help! Currently living with my mom and the house smells so bad like dog. We’ve experienced a lot of change lately, but the biggest one is my sibling bringing home a German shepherd puppy. My other sibling moved out and took their cats which finally put an end to them peeing on EVERYTHING. 🙃

My sibling has a room of their own in the basement, so that is where they and the dog stay. The stench has made its way up to the entire first floor. It’s gross and embarrassing. I’m a single mom of 3, so I can’t move out yet as it’s unfortunately not doable financially.

I’m a very clean person. I am constantly cleaning throughout the day and doing laundry. Despite my efforts, it worries me that my kids smell like dog or possibly even cat pee, because that smell never leaves. 😭 I will take any and all advice/suggestions.

Thank y’all in advance!!
