Roommate Refuses to Walk Dog

We moved into the apartment a few months ago. I knew my roommate had a two year old high energy dog but didn’t realize hed only be house trained. He can barely walk on a lease. Ive noticed she refuses to take him on actual walks and just takes him outside to go to the bathroom maybe 15 minutes a day. Because of this he’s insanely bored. Hes very destructive and gets in the trash constantly. We locked the trash and he managed to break the hinges. We crate him and he breaks the crate. Idk what to do, he was alone for 10 minutes and he already got into the trash. I know she has good intentions but theres always an excuse about why she cant do it. I realized he needs to live a better life. Maybe someone has tips to help with talking to the roommate. Ty
