Hi Michelle, Millie and family! Welcome!
Sounds like Millie is a typical Doodle all right!
We call those energy bursts "doodle 500s", "zoomies" or "happy dance".
You are beginning to find out that a Doodle is a very different creature, eh?
You are among believers here!
We are so happy that you joined us and I look forward to getting to know you better...Millie is a beautiful girl...were either of her parents blue?
