Add chicken to your slow cooker. Top with your dry Italian seasoning and Italian dressing. Set crockpot on high for 3-4 hours, or low for 7-8 hours. If you find that you need a little more liquid during cooking, add a 1/4 cup or so of water.
In the last 20 minutes of cooking, shred the chicken using two forks, top with the cream cheese, and stir.
