Steve White presented this video at the APDT conference last week. It’s by a UK trainer, Chirag Patel of Domesticated Manners, whose Youtube channel is definitely worth visiting. Here’s a lovely demonstration of how he teaches a Drop cue. It’s very similar in some ways to how I introduce my Leave It command, although those exercises include the additional goal of reorientation and movement away from the item.
I really like how Patel uses his hands to help the dog find the food from the very beginning, and find the narration very thorough and instructive. I also like that he included a handling mistake in the final cut, explaining what he did wrong and demonstrating a corrected approach immediately afterward.
