just took the puppy [ Marshall ] for a walk in the neighbor hood with out his leash I had his E-collar on and need to use it twice when he wondered off too far from me we went about 300 yards as I did not wan to go too far he is getting better with each day

I saw this video showing one portion of the Sky Marshall qualification... Probably not something you want to practice at the local range .

I like his views on gun control.
