Dog abuse update

Not sure if anyone remembers but I posted about an abused dog a few weeks ago. My uncle has been harming this dog. He’s terrified of him. I went into more detail before but it’s disgusting how he has been treated. anyway, as of tomorrow he will officially be in my care now!

Any Advice on how we can help him settle and make him comfortable. Hee cowers and hides in the corner and cries at the moment. Especially if you stand around him.

Is it possible to reverse the affects of abuse?

We also have another dog, he has never been housed with another dog but has met my dog and they get along
