-Be sure you have the dog's attention before attempting any cues!
-Say cue ONCE -- clearly, quietly, but firmly -- and pause to give dog time to respond. Be patient! Many dogs take a little while to process information. Do not repeat the cue unless dog is distracted or does not appear to understand.
-ALWAYS mark (with "Yes!") and reward (with treat, praise, petting, etc.) EVERY correct response! This is CRITICAL!
-Use of physical prompt is NOT desirable and should not generally be necessary. Only use if dog seems confused about cue.
