Lol oh no! You can borrow my dog, he's a 95 lb pit bull and has been keeping raccoons out of my backyard for years now! I know what you mean though, I brought him on a leash to try and scare the raccoons out of our front yard pond, they didnt even care...just kept on destroying my plants and eating my comets.
But they won't even get over the fence into the backyard anymore. The last one that did, was chased at top speed 1/4 acre across my yard, climbed up a chain link gate and sat there for hours waiting for my dog to leave. But he just stood there, up on the fence barking. It's that pit bull blood in him, he doesn't give up haha.
