I hope Logan sees this!! Her girls have had many a night stalking the evil possum!! My Cody and Star both have chased and caught mice, rats and squirrels!! Star my Lab not so much anymore (she was bad when she was a puppy!) But my Husky/Shep Cody will chase squirrels right up a tree! Once, a year or so ago, they had a skunk cornered and got sprayed badly! Luckily the skunk escaped into the woodpile! Some dogs just have a stronger prey drive than others. Harley's a Terrier and their job was once to chase and catch critters. I know raccoons can put up a fierce fight and can injure a cat or dog badly. Now, although I have a fully fenced in backyard, my girls only go out at night on a leash, just in case! I live in a very wooded area that with critters all around. My husband often says that I shouldn't be surprised they do this when I have a whole basket filled with stuffed, squeaking squirrels, hedgehogs, frogs and such!
