7 year old retriever mix needs forever home no kids or pets (Englewood)

My sweet affectionate retriever mix was attacked last year by a pitbull and now she herself is becoming aggressive.
She attacked my other dog.
She has NOT shown any aggression towards people but in an abundance of caution I am asking for a kid free pet free home.
She loves to play and sit on your lap.
$30 rehome fee.
She is spayed and up to date on shots and microchipped.
