So I was wondering what everyone thinks is a must have for training. Such as whistles, e collar, bumpers, crates, etc. What are some other things a first timer should have on hand and which ones are recommended? I get my hunting partner back in month or so and want to make sure I have everything I should need for keeping him sharp along with what will be needed during hunting season. Just going to be a hunting dog and go everywhere dog such as work and to the river on weekends. Thanks.
