I've got an idea of a few hand signals that work in training but am trying to get a better idea of the hand signals commonly used. What works for you?!
I most likely do not use "proper" hand signals but they all work for the result desired.
A fist = sit
An open hand with a slight lowering motion = down
An open hand held in front of face or extended from my body = wait
On one knee with my forearm across my body in front of me = perch
One hand making a motion like somebody is always yapping = speak
Both arms wide open = come
Most any dog is smart enough to equate a body gesture or hand signal to whatever desired result you want.
