My family as a whole has had 12 total... including the current four.
That said, I personally have only had 3 (Tango, Dance, & Spring). As in, those 3 dogs were specifically mine and I was/am solely responsible for them as far as food, veterinary care, training, etc. go. There was a fourth, Jesse, who made herself mine when I was younger, but I was a young kid and wasn't responsible for her really at all. So I just consider her a family dog. I fed her and trained her and played with her, but that's about it.
