I'm so excited, we're getting a new baby boy in a few weeks! He's part chihuahua and part toy poodle, just a tiny thing right now, and not expected to get over 6-7 lbs when grown. I have an opportunity to get a second puppy, a pure breed chihuahua, from someone else. They're 3 weeks apart in age but should be around the same size when grown. What would y'all do, get just the one or get two? If two, would you get two males or one of each?
