Prior to training your dog, the biggest, most important tool that you need to have is patience.
 Also, you must be very consistent and work with your dog everyday during its early part of their training.
 Doing so will almost guarantee success.
With that being said, the first and most basic dog trick that you should teach them is the sit command.
Get your dogs attention by calling its name and establishing eye contact.
 Make sure that you have a good amount of your dog's favorite treat.
 Hold the treat at nose level, just out of the reach of your dog.
 Be very careful not to hold the treat too high as this will cause the dog to jump up at it, which you don't want.
  The next thing you want to do is to slowly move the treat directly over its head towards the dog's tail.
 Make sure you say your dog's name as you do this as well as the command "sit".
 Your dog should start to sit as he or she follows the treat.
 The very second the dog sits, give praise immediately as well as reward them with the treat.
 Repeat this a few times.
 Give a lot of praise and refrain from saying "no" too much.
 Make sure you repeat this 2 or 3 times a day for a week or so.
 Remember to stay consistent with everything involved with the training.
  Whenever your dog gets the sit command down pat, it is then time to move onto the down command.
