This morning we met with a training friend. She had mentioned that one of her dogs needed work with leaving food during training sessions. Her other dog had similar-but-not issues, being distracted by people (potential friends). Essentially, it comes down to the same self control challenges.
We both brought a set of 3-4 food leave it exercises. Some of them were similar, some were very different. We got through about half of them this morning and we'll meet on Monday to do the other half.
It's interesting to work on the same overall theme but with different exercises. Part of the myth of clicker training is that it's just "one way" of training. Any scenario can be approached many different ways and doing so will allow the dog to have a more complete understanding of the concept.
