Doggone it, Richard B., now you've got me wondering just what we had there. We're talking a lot of years since we acquired him, but I could have sworn he was sold as an " English Sheepdog" or "English Shepherd". I know he was no collie, and he didn't match any of the others you listed; of those, an Old English is the closest, but he didn't have anywhere near as shaggy a coat, or hair over his eyes. He was mostly black, with white boots, chest, and stray markings.
I wish now I had a picture of him around.
