Start by training your dog to "sit." Building a solid "sit" command places you in control of a whole variety of situations. For example, if your dog hears the doorbell and rushes to bark, you can interrupt this behavior by asking it to sit, then rewarding the "sit," and removing the dog to a back room where it won't bark.CLICK HERE https://bit.ly/3N34CEW
To teach sit, show the dog you have a treat in your hand. Show it the treat at nose level, then arc the treat up above its nose. Say "sit." Your dog's head will follow the treat, leading their head to go up and it's bottom to go down. The moment their bottom hits the ground, click-clack the clicker and give it a reward
Once your dog is doing this regularly, start to skip the treat. This builds unpredictability in the dog's mind about whether he or she gets a reward or not and stops it taking them for granted. This means the dog works harder. Eventually, just reward every fourth or fifth command.
Once your dog is sitting regularly on command, ask him or her to do this when out and about, before putting its food down, and at the curbside before crossing a street.
