Grew up with my mom fostering shelter puppies my whole life, always had at least 4 dogs in the house. Being a broke college student I can't afford to have a dog of my own right now and it breaks my heart. But this is a lovely alternative to satisfy my love for your four legged friends. I've had every breed from Yorkie to Great Dane. Although I don't think big dogs would enjoy sleeping in my apartment I can still walk them for you!
