Beautiful sweet Brindle Hound/German Shepard Cross

She is very sweet and super loyal.

She is pet friendly for the most part but my cats don't like her.

She was rescued by me a couple of years ago as she was a puppy mill. She absolutely loves to be with the family and obeys incredibly well. She is a good guard dog, but has a mean bark which scares people. She has never nipped at anyone but she doesn't like people with hats on and is protective. She could use some training with this.
