Raccoons were a big problem where I used to live in Cincinnati, Ohio. They were fearless creatures, coming up to the front door, staring in the windows, and going through our garbage. Our outdoor cat got into quite a few tousles with them.
One night, about two years ago, our giant German Shepherd, Schultz decided to deal with the ruffians. It was midnight, and my husband had let Schultz out for his last potty break. The coons were at the bird feeder, stealing seeds. Schultz spotted them right away and charged. You should've heard the commotion! There were four coons hissing, and one very irritated German Shepherd growling and barking. The scuffle lasted a few minutes, then all four coons climbed over the fence and retreated. Apparently they didn't like a very scary-looking dog with large teeth charging at them.
Schultz stood at the fence with his hair standing straight up on his back, making sure the coons were gone for good. When he was satisfied that they were, he gave another bark and trotted into the house.
He wagged his tail, and looked quite pleased with himself. "Good boy, Schultz," my husband said, giving him a treat.
(Schultz must've made quite an impression that night, because we never saw the coons in our back yard after that!)
