"Well, that was an unusual situation," says Berg, "And I'd caution anyone not to push for this type of result so early, or to even try this with a pup that young, but I had worked this pup on whoa, both on the bench, and playing fetch. I'd mix in whoa while playing retrieve. I'd throw a ball, then gently restrain him while saying whoa. When he was steady for a bit, I'd release him. It was a fun game and the retrieve was his reward. You want to make it fun for the dog. Keeping it fun is very important, and letting them learn on their own with wild birds or strong flying liberated birds."
