BARN HUNT is a scent sport, where the dog needs to learn how to use the tools naturally given to them to locate the hidden rat, and the handler needs to learn the dogs cues so they can interpret the dogs findings correctly.

Our friend Paula at Summerfield Rottweilers introduced me to Barn Hunt. Paula was my original mentor for Carting and encouraged me to the first AKC Rally trial.  Then she got me interested and earning AKC Tracking titles.... now this!  She kept talking about Barn Hunt, but it sounded silly to me..... till I tried it.  The dog needs to locate the tube that has the rat. The rats are hidden out of sight in a safe tube and the handler has to call their locations based on the communication of the dog. As you progress in the levels, there are more rats to find as well as more tubes without the rat but include rat litter to challenge the dogs to indicating the actual rat.

An additional challenge in the Master class is that the handler needs to tell the Judge when the course is "Clear"-meaning they are confident there are no more rats prior to time running out. 
It's a random draw whether you get 1,2,3,4 or 5 rats! Every run is different.
