I voted 3, when in actuality, my limit was 2, but then I met Scott, and of course, we added Murphy to our bunch. Zipper was an unexpected surprise, totally unplanned, as he was supposed to be a foster until he was adopted. Only we all fell in love with him, as did our 3 canine girls! So, we have four, and are definitely setting a new limit. But it is fun (except for all the poop scooping that I end up having to do!).
