Just wanted to introduce myself. I'm Dan from Denver. Thanks to all for the great info on this site. I got my first dog ever about three months ago. Cassie is a year old black lab mix rescue dog. I never realized the profound positive influence a dog can have on a person. They will cheer you up, make you laugh, and keep you active. Now that I have a dog, I can't imagine living without one. Truly "man's best friend". I am on a quest to find the perfect diet for her and this website has been an excellent tool to get me started.
