I just wanted to give you an update and let you know that Addy is doing great. After a couple days of going back and forth on her name, we decided that Maddie was a perfect fit for her (not to mention it's so close to Addy that I doubt she realized we changed it!).
It took a couple days for her to be herself and to become comfortable, but that is to be expected after a transition. Other than that, she loves playing in the yard and sometimes I'm convinced she likes eating leaves and twigs more than her own food! With that said, we're currently trying to teach her "drop it". :) She has lots of toys and is playful and energetic as ever, she seems to be perfectly happy now. We love her so much!
