This is the key to reading your partner and how your partner feels at any given time. You can accurately decipher what your dog’s mind and body is truly saying. If your dog is comfortable in what you are teaching, his body should be relaxes, happy and he should appear to be content. If your dog is exhibiting a discomfort behavior, he may appear to be stressed, anxious, tense, fearful, unhappy, and more. You will not dance well with a dog that is not comfortable.
