Teaching a dog to stop and remain motionless IS NOT teaching a dog to point! Whoa is, or should be taught in the yard without birds and then when the dog points, whoa can be introduced to keep the dog from moving. You try to teach whoa in the presense of birds and you will likely end up with a blinking dog that is going to shun the birds when he smells them instead of pointing and unless they flush wild, you want even know they were there.
