I think its a win win for your daughter and the other dog. Two is a great number and they will keep each other company while you work. The older guy will have a reason to get up and play and stay active and the little one will have a mentor. I had a golden retriever for 11 years and got him about the same age as your little guy. The BEST dog I've ever had. Your guy is well on the way and if he considers his crate home, even better. You have reservations but consider that your breed is smart, loyal, and very trainable. All my dogs started in the crate. It's a great training tool and a security blanket when they get older. Congrats. He's ssooooo cute!
