Shelly, I have a yellow lab and a shih-poo. I had been told when we first got our lab to just go get a second dog right away because it makes life so much easier. I thought that friend of mine was crazy. But finally I decided that I wanted another dog, just smaller. So, I got our shih-poo. Our lab, who is high strung even at the age of 2 now has a play mate. He is more mellow, and doesn't chew on things like he used to. The shih-poo loves him, she has been easier to train commands to being that she sees our lab doing things and she just follows suit. Plus as a puppy, she doesn't chew up hardly anything because she has our lab to play with when she's bored. Granted, our lab does get annoyed when she decided that his ears where a great alternative to raw hides. LOL! But I would recommend that you do get a second dog. I think that both dogs and your family will not regret it.
