I know what you mean, Tp3, things change a lot when a second dog comes!
Anyhow, I've decided not to get a second dog yet. Uma has had some "incidents" in the past few weeks that have made me realize she probably still doesn't feel 100% stable yet with us. As much as I wanted a second dog for her to have a friend, she's shown me that we still need to work on bonding and making her feel secure.
