Remy needs a new home (Tucson)

Remy is a five year old Black Lab, maybe Akita maybe hound mix.
We rescued him from PACC three years ago as his last chance.
He had been living on the street for a while.
He had developed some aggressive tendencies and had bitten on at least three occasions.
We were his last chance before being put down.
He picked us and had become friendly even with strangers.
We love him but unfortunately he needs a new home now.
He's a good boy.
Please, someone who will take over and help him please answer.
Text nine 2 eight nine 7 8 ten seventeen.
Please help this good boy.
