RE: Specifically for dog trainers!
TreestandEd is right only I would also concider getting some live birds if you can find access to some. There is nothing better then live birds for training your hunting dog. I use Live quail. If you dizzy them up a littel bit and place them in cover they will sit tight most of the time. give them enough time to recover and work the dog in that direction. Check your local and state laws but then you can flush and shot the bird over the dog and give him the same comand you do when you tell him to fetch in the yard. Live birds have a way of really getting a dog fired up on finding birds. also it is an added expence but you can get a bird lancher, manual ones are cheaper then remote ones. Check out the internet for Lion Contry Supply, Cabela's or Bass Pro Shop for a launcher if interested.
