The GSDs I grew up with would do it pretty immediately, but I had to occasionally praise them when they did it so they wouldn't lose the habit. They're pretty damn smart and will figure out some pretty complex behaviors just from positive reinforcement. I once taught a GSD in one session to sit patiently 10 feet away from the vehicle gate at my childhood home when I arrived home by stopping the truck every time started walking forward. By the 3rd or 4th time of my inching forward he had figured out that the only way to get me to pull in and get out of the truck was to sit patiently and I never had to train him on it again.

Crappy owners. The GSD I have is like a cyborg, yet very friendly. WFH help the training. Most owners do not train their dogs and the alpha in GSDs come out easily.

I've never even taught it to my dog, as she just drops toys at my feet after fetching them. She just enjoys the though of the stick being thrown too much to waste time on holding on to it.

This tool is incredibly effective. ive zapped myself with it to test. feels like a very very strong static shock. Our dog Solo has been zapped only a handful of times. When he wears the collar now we don't even really turn it on or use it - just knowing it exists is enough for him to drop his frisbee/ball/etc. https://www.ecollar.com/product/ez-900-easy-educator-1-2-mil...
