Other likely symptoms include: 1  radiating pain in the face, jaw, or neck, 2  jaw muscle stiffness, 3  limited movement or locking of the jaw, 4  painful clicking, popping or grating in the jaw joint when opening or closing the mouth, 5  a change in the way the upper and lower teeth fit together.
Then you can train your dog to walk to heel, and prevent them getting the opportunity to pulling on the lead. Every time your dog gets to pull on the lead in the middle of your training program, they are getting a chance to perfect the pulling habit and reducing the effect of all your hard training work.
When you ask a dog to heel you are asking the dog to come to your side, by the heel of your foot. You want to teach the dog to follow you in the heel position. That is, if you begin to walk, the dog will follow at your heel without pulling on the leash, if you stop walking the dog will stop as well.
