This video is great. My German Shepherd is the exact same way. She will run and hide. Even though we haven't given her a bath at the house in over eight years but every time we open the closet door that has towels inside she runs and hides. The best part of her 'hiding' is that she doesn't realize that we can see her big ears behind the couch. Nice try Ella.
Needless to say, we take our dog to the groomers. Its much easier than fighting for it every time at home.
Some of these dogs are pretty funny they won't take a bath without a fight.
