Ugh, I don't know what to doooooo!

I keep going back and forth. I fell in love w/ a puppy over the weekend, and I want to get her! She actually is very laid back, like one of you mentioned would be good, so maybe that's a sign it's meant to be?

I think it's smarter for me to just have 2, but I think having 3 would make me happier?
