We live in a three story townhouse (stairs might be an issue for older dogs). We have dog gates to separate the floors. I can always carry them up/dog if the stairs will be an issue. I work from home Monday - Friday and free most weekends. My roommate has a medium sized female golden retriever who gets a long with other dogs (she just turned one) I can always separate if needed. I do work from home during the day but will be with me all day/nigh & I can play and let them out every couple hours. My family has 5 dogs (two labs and three Pekingese) and have had a dog myself so I’ve had a lot of experience. I’ll take the best care of them.
