Hi! As far as a different food.....I would reccomend Life's Abundance
Welcome to TrilogyOnline Pets
Even my most picky eater LOVES this. Its made with the freshest, high-quality ingredients, which gives your dog the best quality possible! It is a dry dog food that contains all natural chicken and top quality catfish with the best fresh fruit, vegetables and select farm foods. Life’s Abundance also contains a superior blend of vitamins, minerals, and antioxidants important for healthy dogs. Contains no artificial flavors, colors, sugars, or chemical preservatives.
It also has NEVER been on a recall list
If you'd like to try it, I'd be HAPPY to send you a free sample for you to try!!! Just send me a PM with your address and I'll send it right out
