Crazy Raccoon Attacks German Shepherd

Here is what happened: I heard my dog barking as I was at my neighbor’s house. A raccoon came into my yard, ignoring my barking shepherd. Then the unthinkable happened, it proceeded to go through the fence facing the shepherd. It climbed up a tree, fell out of the tree, hit the shepherd, and then ... see for yourself. This is a good reason, why you have to vaccinate your pets! Anything can happen, and this was in broad daylight. For all I know, this raccoon could have distemper, or rabies, or was just stupid ...?
