Teaching your dog to sit is one of the easiest tricks you can teach. Sitting before being given a treat or getting their leash put on is sort of the canine equivalent of saying "please"- and for goodness sake, you should teach your dog to say please!
To teach your dog to sit, just get out a treat (a piece of dogfood will work), Say "Sit", hold it up and move it back over his head. Most dogs will sit just so they can keep an eye on the food. When the dog sits, give him the treat and say "good sit".
For dogs who don't sit automatically when you hold the treat over
their head, you can physically help them by holding the collar and
pushing down on the hindquarters. Remember to treat and praise as
soon as possible after the dogs hindquarters touch the ground.
