okay -- how to make it better -- not enough frustration for the dog . You want good bite development , don't give the dog the bite. You have the flirt so far back , flip it twice , then the person comes running to the dog and feeds the thing , jams, it into the mouth. Even here the person could have fooled the dog , taunted him with it oh so close and then moved away and teased him more.
If you had teased the dog up closer , making the dog think it can get the toy , then move back , sneak up closer , or move back and allow the dog to get some ground by allowing him a moment of chase , moving forward when you have maximum stimulation of the toy you would have more intensity . this is after all PREY development . make it prey.
