I retired couple down the street have a greyhound, which was a rescue from, I think, Wisconsin. It is one of the mellowest dogs I’ve ever seen.
I hear greyhounds are sort of like Dobermans as Dobermans are essentially half greyhound. Dobermans can be a task. They aren’t like other breeds. They are nothing like Labs which are what most people are used to. Labs are sort of the Forrest Gump of dogs. Dobies are pretty suspicious and can be downright devious after dark. Once you can convince them you are part of the team they really bond to you like no other dog. I call my male my “shadow”. Where ever I am if you look in my shadow, there he is. Just watching. Waiting.
