Sam has been adopted!!!

Meet little Sam!
For adoption. He's been adopted twice and both times returned, how much can a little puppy's heart bear?
Returned for no good reason too, not because of him, hes an intelligent good little boy, just longing for a home. He looks at houses through the window of the car...
A parvo survivor, male.
Around 4 months
Both vaccinations done.
Please someone give him a loving home...
He is not infectious and will never get parvo again, he's a survivor, please give him something to live for...
