... to improve your relationship with your pet
Your self confidence starts with you. You may not have any say in what others say about you, however you have complete say in what you say about you. Self-confidence starts with improved self-talk, not the egotistical "I am so good" (as that still stems from lack of confidence) but in the humbly unapologetic and loving version that say "this is me".
Stop wondering what your pet is trying to tell you
