German shepherds are highly intelligent dogs and you are starting obedience training right out with the pup. However, things aren't going quite as you'd planned. OK, he's learned to sit just fine, but you can't seem to get to grips with 'stay'. You turn your back and walk away but the pup comes bounding after you. While it does your heart good that he wants to stay by your side, this isn't so great from a training perspective.
You suspect it's you that are sending out the wrong signals, but this being so, how should you teach 'sit' and 'stay'?
In practical terms, you will take one step away from the pup, then return to his side and reward him if he remained seated. Again, make sure the pup stays put reliably before adding in a second step and gradually extending the distance you walk away from him.
These training sessions work best when done 'little and often'. Thus, several short sessions during the day are much better than a single longer training episode. Also, as the puppy gets the hang of things, vary the places you train him so that he learns to generalize the commands and not just execute the perfect 'sit and stay' only when in the living room.
