Teach Your Dog to "Stay"

This command shouldn't be taught until after your dog knows the "sit" command.  With treat in hand, have your dog sit and instead of then giving the dog the treat, say "stay" (make sure you have his attention.)  Give this command firmly.  If he "holds" the command for even a few seconds, praise him and give him the treat.  This command can be given in a sitting position or lying down but is easier to teach when sitting.

This command takes some patience as you'll have to work at gradually lengthening the time of the "stay."  Be sure to reward your dog for even small increases in the time they hold their "stay" position.  If he moves too soon, simply start again with the "sit" then "stay" commands.
