For both scent work and mantrailing there is not lots of kit involved, so once you have the basics, you are good to go!
Mantrailing requires your dog, harness, long line, 2 x small pots and soft food, and/or toy. You also require a Mispa (missing person) who will go and hide for you. They require a scent article to leave behind.
Scent work requires your dog, harness, long(ish) line or flat collar and lead. Scent to hide and high value rewards. We use clickers to mark the scent (but marker words can be used also).
