Well, now I've seen everything. They've actually got ghost shaped dog biscuits. Are they supposed to scare the doggie and get him to flee his food dish? "Oh, my dog biscuits are white now? Not bad. Yum. Give me more, please and I'll make you think I like you."
Actually, I used to take my dad's dog trick or treating. He got a lot of goodies. I could see, as more dogs get in costume and go trick or treating, where these ghost dog biscuits could be fun. Just don't delude yourself that fido get's the ghost concept.
Of course, Zeto got really into Halloween. He got goodies and I even made him costumes to wear. When he saw me carving the pumpkin he got really excited--even more so than when the Christmas tree went up. This Halloween stuff was for him.
