I'm hoping someone can help me out here. A couple of weeks ago I was at someone's house and they had this gorgeous dog. I asked what the breed was, but of course I forgot - twice. Anyway, the dog was still a puppy, but he was already a large dog. The owner said he was only going to get even bigger. Her friend told me that every week when they first got the dog he would grow a one-third bigger than he was the week before, so he grew pretty quickly. The first thought I had when I saw this dog was that he looked like a bear. He had puffy dark grey hair, very large, and was very quiet. His owner said that he is a quiet dog and very good with kids, completely even-tempered. She also said that he was a kind of Belgian Sheperd, but he didn't look like any that I had ever seen. If anyone knows of any breed this could be please help me out. This has been driving me crazy for weeks. I fell in love with him and would love to research them more!
