I noticed he’s developing a proclivity to stand over anything I set on the ground to keep other dogs away from it. Tried it with my saw on a jobsite the other day, set it down and walked off and told the man what I was wanting to see. Ace went for the guy who started to pick it up. Aces speed, and aggressiveness spooked the man so bad he forgot Ace couldn’t reach him. Thought I would see if it applied to anything and anyone. It was my wife reaching for my wallet. He wasn’t near as aggressive with her, just an annoyance bark.
Once turned loose with my wallet he will usually get it and bring it to me the couple times I have tried it.
For a 1yr old figuring out they are mine I am impressed.
