None of the videos I've seen and the program I'm following mention teaching hold with birds. Do any of you do it or should I do it? When do you teach hold with birds? My pup is doing hold while going through her OB very well so I'm thinking that now would be a good time to use birds while doing the hold command/drill but I want to see if there is any pitfalls I might be walking into or if its a bad idea for some reason. Thanks.
