#5 – Finger Pointing Down
This is the most common sign for telling a dog to “lie down.” Like the one for “sit,” it’s natural to do and easy to remember (which is important).
#6 – Hand Flat Out
You can use this symbol for “off,” or to teach your dog a “stop” or “freeze” cue. Just remember you can’t use it for both, so decide in the beginning and stay with that decision. You will really confuse your dog if you try to switch the meaning later.
