Imagine that it's dawn and the sun is just peeking over the horizon. You are sitting in a duck blind, listening to the sounds of nature. Your loyal dog is curled up at your feet, patiently waiting until he is told to do something else. Suddenly, you hear the sound of ducks overhead. Your dog moves into the seated position and you remind him to hold the 'Sit'. Your buddy knows what is about to happen and he eagerly waits for the opportunity to spring into action. You take aim at one of the ducks, and as you do so you are reminded why you love duck hunting.
There are many important skills that a dog has to learn in order to become a loyal hunting dog. Using a blind is one of those skills. Just like the hunter, the dog must stay hidden from view so that he will not scare off the birds. Even more importantly, teaching him to stay next to the duck blind prevents the danger of him being in the way.
You can generally expect it to take between one and three months to train your dog how to use a duck blind. Your pup will probably learn what to do in a matter of weeks, but it can take longer for him to learn how to do it around distractions and for long periods of time. If your dog already knows how to maintain the down position for long periods of time, then he should catch on to this even quicker.
If your pup finds the blind scary when you first introduce it, spend extra time getting him comfortable with it by making the presence of the duck blind extremely rewarding with treats.
If you choose to use the 'Sit' command while using the 'Sit Down' method, make sure that you do not let your pup out of the sit position at any point until he is given his release command. It is important for 'Sit' to automatically include staying in duck hunting work, so your 'Sit' command needs to be very consistent with what you will require later on during duck hunts.
