Dog are super smart and they love to get rewards. So, to make your dog sit, all you need is a few treats and some patience.
Stand in front of your dog and say, “sit!” If he sits, give him the treat and say “good boy!” or “good girl!”, then make him walk around a little and do the same thing again. If he sits again, give him another treat.
But if he doesn’t sit, there’s an easy way to get him to do so. Dangle the treat in front of his nose while saying “sit!” If he still doesn’t sit, move the treat over his snout to the back of his head. You’ll notice his nose will follow the treat and he’ll raise his nose. As he raises his nose, his backside will automatically drop to the ground. When he sits, give him the treat and say, “good boy!” or “good girl!” and praise your dog. Give him scratches and love.
Keep doing this over and over until your dog knows that the word “sit” means he has to put his backside down.
See? You’re smarter than a dog!
