Luna needs a new loving home

We have had Luna since November 2021. She is a lovely dog, and loves long walks. Quite anxious and licks lots.
She has been around our 3 kids and our older dog. Doesn’t bother with other dogs much, however needs to be alpha and has snapped at a few dogs (mainly females) if in her space.
Has become a bit unpredictable with people and needs attention/support in a quiet home.
Adopted at 7 months old with prior abuse and chained background.
