I know that details depend on the specific shelter or rescue, but I have some general questions about the experience. I imagine that in some ways it's similar to having two (or more) dogs, but how is it different? How important is having extensive dog experience? Is it advisable to begin by volunteering in a shelter or rescue? How do you know if your current dog(s) will respond well? Do you need a way to keep your current dog(s) and the foster separated (like a room or area of your home you can close off)? What advice do you have for someone interested in fostering?
