One would certainly be a lot easier in many ways. I've had just one dog before, but most of the time, I've had multiple dogs. I almost can't remember having just one dog. I do like having two little dogs. They're easy since they're Chihuahuas and they're such playmates. I like that they have another of their species to hang with besides me. I have three now, but I think two is my magic number. The most I've had at one time was 4 and at one time, 5 (a temporary). That's really a bit much for me. And I don't know what I'd do if they didn't get along. That would really be hard. So, I am fortunate that all three are so in tune with each other and such friends.
