Instructions
Begin by positioning the dog on its back or side, whichever seems to be more comfortable without causing the dog to act aggressive. Nipping or biting are signs that the dog is not comfortable.
Avoid eye contact with your dog while teaching it to settle down and refrain from squirming. You need to establish that you are the leader and that you mean business.
Gently hold your dog down in this position and say the word "settle" in a calm and firm tone of voice. Every time your dog squirms, use a firmer grip and repeat the word. Continue to do so until your dog stops squirming. When the dog behaves appropriately, be sure to praise it for a job well done. A treat can reinforce the action as well.
Link the settle command through other behaviors, such as a "sit" or "down" command. Require your dog to stay in that position until released by holding it and repeating the word "settle." Remember to reward the dog with a treat and lots of praise when it does as instructed.
How to Handle a Squirmy Dog
Most dogs are squirmy and overactive as puppies, but settle down as they mature. Some dogs, however, are extremely active throughout their entire lives. These dogs are just as wonderful and intelligent as most other dogs except that they have a shorter attention span due to their adrenaline and active behavior. With special techniques and extra patience, you can handle your squirmy dog.
