Pointer Pup Learning to Flush on Cue

The pups are 4 months old now. All are doing well. Here is Biscuit practicing the "flush" cue (I use the word "alright"). We're also working on her "stop to flush". I always use good flying birds that the pups can't catch. Her chases are getting shorter and shorter. Soon, she will stop chasing all together. She will learn that the best way to consistently get a bird in her mouth is to stop chasing and instead, be steady at the flush. Being steady to flush is always rewarded. Either by me offering a bird or her being allowed the retrieve on command. Chase = lose, Steady = win. Pretty simple choice.
