Boxer mix free (Oklahoma City)

My aunt’s neighbor left there dog chained up when they moved so my grandmas been taking care of him, she’s old and disabled so it’s hard to do so.
He’s high energy and very sweet, I have 1 small dog and he did well around her.
I’m not sure what his name is, but he’s takin to the name “Skoden” but obviously that can change, he looks like a boxer mix not sure what else.
A small 25 dollar rehoming fee so he goes to a good home, he’s a little emaciated but he’s getting better.
