When introducing young pups to birds for the first time I like to use a clipped wing pigeon. This is done by plucking or cutting the main 4-5 flight feathers on one wing. The bird will still be able to lift off and flutter, but not fly away. Some puppies will point the bird, some will charge right in while still others will stalk it slowly like JJ in the picture to the left. I really want to see their prey drive and how much they want to get that bird. It is amazing how differently each pup in a litter reacts to the same situation. I use this drill as a yardstick to measure where I need to start their bird dog training. Generally, bolder dog can move along at a faster clip and progress a little more quickly. The timid or reserved pup will take a little more time as you build her confidence and keep things lighter.
At some point I like them to actually catch the bird and mouth it a little. This is a great time to test the pups retrieving instincts. All puppies love to pick things up, its the getting them to bring it to you that is the tricky part. Some pups will bring a bird right to you without much coaxing, while others will run away to enjoy their bird. Either way be sure to pet them up real good before you take the bird away.
