Once you have him started on his basic commands and he is showing some degree of interest in the wing training I suggest building a small quail pen for 2 or 3 birds and have it in your back yard. Everytime you take the pup by themsay "birds"and let the pup jump up at the pen and hopefully he shows excitement for the birds. At this stage you don't have to worry about whoa training and worrying about him jumping or flushing birds in the field. Don't introduce him to live birds in the field until he is at least 4 1/2 months old. Build his bird drive and confidence by using the penned birds. The dog has to look at the training as fun time not work. Let your pup be a pup for the time being and tighten up the reins a little when he is 6 months old. Do not put an E-collar on him until he already understands and does the commands you are training him on. Do not shock him while he is at the bird,it could cause him to become scared and unsure when he comes across the bird in the field, establish whoa training and all other training at home in the yard before taking him to an unknown place and expecting him to learn commands. Reward him for doing the commands correctly and if you give a command make sure you follow through and have him do what you command ALL THE TIME, if not he may learn that it is ok to listen to you some of the time. Hope this helps. For me the experience and time spent with my German shorthair is rewarding. You will have more pride in your dog and yourself if you are the one training him and responsible for his acheivments. Letting someone else train your dog is like letting someone else fill your deer tag. During those training sessions his bond with you will increase and he will want to please you first before anyone else.
