My older cattle dog will go nuts at "squirell", "kitty", or "get em". He'll grab whatever toy or blanket or shirt is nearby (or your arm, if that's what's available) and thrash it as if he's trying to kill it. The kids friends find it hilarious to sic him on each other.

Back when I was running and competing in NSTRA with my German shorthair, and English setters I had the whoa train or they would stop on a dime. It didn't matter if they were 600 yards away if I hollered whoa they wouldn't move one of my short hairs would literally slide in the mud 6 feet not moving her feet from the time I said whoa. It was good for training and getting them to not bust birds when they're on point it was really nice if they were running and getting ready to cross the road or somewhere where there was traffic and you can see a car or anything coming you can get them to stop. I would also trying to where they would point if I said bird but that was a trial cheat if they didn't see your smell of bird and I did I could get him to a point and I can flush the bird and throw it up or shoot it if it flew on its own and get the points to move on and find the next bird. Another trial cheat was when they learned to 4wheeler track,. Since they put the birds out in the field on 4 wheelers if they tracked the path it took they would find the birds much faster vs searching the entire field. I never trained then for that but the smart ones picked it up on their own.

My little Red Lab “Kit” will get me a beer out of the shop frig.
