This is how my almost I think not sure because we rescued him Diego from a pound so I guess that that's more of an adoption. He'd been there nine months and they guessed that he was six weeks old when they picked him up. He didn't bark or wag his tail for years. We worked with him as best as we knew how. I worked with him as best as I knew how. An Aunt raised dogs for years and advised that our now deceased Garcia dog to train him or for Diego to learn from him. To let Garcia do his thing with Diego I guess, IDK, I know but words aren't my forte. He had nightmares for a few years. Whimpering in his sleep. A friend once commented that Diego seemed like he had had a lobotomy which I thought was rude but whatever I don't think that the guy meant any harm by the comment. Anyway long story short these are our dogs playing this morning. They're rough with each other but no one ever gets injured.
