Start approximately 1 week after getting the new puppy.
Place the pup facing away from you, between your legs. Put your right hand over his chest and your left hand under his muzzle. This is a basic exercise in restraint. If he accepts this handling calmly praise in a soft, reassuring voice and gently massage him. If he squirms and fights to get free, hold him firmly and put him right back in position, saying in a firm voice “No, stay!” As soon as he settles, resume massaging and petting. Any more struggles can be handled in the same way, with a quick shake. Pups come to see this as very pleasant and it forms the basis for “Stay” later.
