Rat Terriers are not like many other small dogs. They love to run and hike outside and have the stamina to keep up for miles. They also love to play, so make training a fun exercise for him. If you start early and are consistent, training your Rat terrier to sit will be one of the best investments in his training. When he sits on command, you can teach him more tricks, keep him safe, and make sure he's paying attention to you.
Make sure you get on his level by either sitting or kneeling, or bring him up to your level by placing him on a crate or stool. Use a firm but gentle voice. You are much bigger than he is and a loud, angry voice will intimidate him. You want training to be fun and rewarding for him, so have patience and give him time to try. With time he'll learn that sitting leads to good things like treats and games, and he'll be happy to listen to your command.
Below you'll find three methods to teach your Rat Terrier to sit. Read through each one and determine which one will work best for you. With some commitment, your dog will know how to sit on command and will be ready for the next trick.
