Target training forms the bones of Error-Less learning.
We teach the dog a target for part of their body: nose, chin, eyes, left paw, right paw, all the feet, a target associated with an action: stay, follow, go around, climb on, and a target for a location, to my left side, on the table, in the kitchen etc.
This gives us a clear and consistent vocabulary to communicate with the dogs.
Good techniques for teaching targets are the equivalent of learning good English: grammar, syntax and spelling. The more skilled we are to easier it is for our dogs to learn.
