Yeah it seems to be more fun for the owner than really progressing a pup.
Yeah mine sight point lizards, song birds, etc but I wouldn't encourage sight pointing too much especially on game birds. Like playing tug with a dog, it might not hurt anything but I am not taking a chance.
I am not sure I ever saw one of our dogs use these methods for long. The "sleeping quail" thing is more of a way of ensuring you are "on the right track". I do not think we used that method on the same dog more than once, except one time on a dog that needed help firing over her. We used it as a progressive way to "up" the gun level to get her used to it.
Once you are ready for it, you test the dog and see how she reacts then, if all goes well, you can progress to live (wild) birds.
Many dogs do not even need this as they get used alongside others during hunting season, but it is a good way to 'ease' a dog into being fired over and see how they react to live birds. That's about all.
But take what I say with a grain of salt.. I am no authority and was along for the ride.. heh.. the benefits of growing up with someone that really knew a lot about dogs
