English Shepard Link to pic is upstream
Looks like my black and white border collie from Miss.
Had 2 border collies with mother from Wales, totally different dogs from Miss. dog. One of my men and his wife
breed dogs for 12 to 15 years. He had to wash out runs at 4 AM
every morning. When puppies were in they were feeding 50
to 60 dogs. One son had a house on same property and helped.
Son died and husband died about 2 years latter and wife got
out of the business.
This is what Bing images brings up. Looks to be a full grown English Shepard with the colors you stated. Beautiful dogs.
