I don't have any videos, we actually took a class through a gun dog training facility in our area. But here is a link to the National American Shed Hunting Dog Association;
Dokken's Shed Dog Trainer
They have lots of resources.
Also, here is a link that my trainer highly recommends:
Everything Shed Dog- Shed Dog Training, Antler Hunting Dogs - that is where I order antlers and such from. Also, Fleet Farm or Farm and Fleet has antlers and training stuff, I think some of the outdoor stores like Cabelas and Gander Mountain do, as well.
Some key things my trainer told us is to train the retrieve separate from the search, then put them together later. Also, many schools, videos, books, etc. will have you start with an antler dummy and add antler scent to it. She discourages that as it just adds a step to the process and in her mind, to a dog, the scent sticks will smell different than an actual antler. Start with a small, real, training antler.
Start small, put the antler under one of the three boxes like a shell game, put it in the house, then just put it in the back yard for him to find, etc. When Yogi and I first started I was just walking along and putting the antler down to hide it. I posted a video of Yogi finding the shed and a long time tracker let me know Yogi was tracking my path to find the antler... I would suggest walking out and throwing the antler a good distance so your dog can't track you to where you put it. Also, you can put them out the night before and then go hunt the next day for a little more authenticity. Just tie an orange ribbon on them or something so YOU can find them if the dog doesn't, lol.
Make sure you buy training antlers of the animal your dog will be searching for. So if you have white tail deer in you area, get white tail antlers, not mule deer antlers. And don't let your dog chew antlers as a chew toy, it will discourage him from bringing them back to you when he finds them. Whew, hope that's not antler overload!
I love it because it's a real world activity and we get out in the woods and get some exercise!
