She IS a Bouvier! However... This is Nessie's coat with no clipping or trimming. This is the original coat on Bouvier's BEFORE they were infused with Briard to make them all poofy and cottony.
I am in love with Bouviers. I know a breeder in Wisconsin and really wanted them but the hair mess was a deal breaker. I went with the poodles instead. I worked at a boarding and grooming kennel back in 1985 and the owners kept a Bouvie for the owners and they showed her when she was younger. She was a show champion, but she was 6 then and they retired her. I loved her so much. Her name was Nap, and we let her roam free in the compound.
She was trained in the guard and search whatever like your pictures show. Just and awesome dog, and an awesome breed.
If I ever have a need for a herder, I am getting one.
