Congratulations on the new Pup! He is going to have a great time and dog is a great way to add to the experience. Our Golden Retriever loves going caching and has turned into quite the tracker. The idea of using the ammo can and tupperware container are great ones for training the dog to help find caches.
We got him a Geocaching Bandana, but I noticed the one for Duke is customized. Great idea! Where did you get it?
Godd luck with the hunting!
