You don't but your dog does. Cut straight from that corps document posted
Any hunter using dogs in legal hunting activities must exercise control over their dog(s), dog(s) may not exceed 6 dogs per dog handler, must have GPS tracking collars, and Blazed Orange Safety Vest worn at all times.
Don’t listen to all the answers, the first thing to remember is Do Not mention what lake you are hunting or they will beat you up about it. You Cannot use lead shot for waterfowl. It is best to look up the Regis or call the COE and ask directly to get the correct answer.
