My Shih Tzus absolutely inhale this! After I research and read the star ratings on all the major brands on the market, I was appalled! Here I thought I was doing right by my pups.. Wrong! Nothing but by products, crappy fillers and additives and perseratives.. On the website all were rated "1 star" out of 6! I had been running back and forth to the vet $$$'s because of allergies, about to chew their feet off and itching. Found out majority of dogs are allergic to corn and wheat and soy, alot allergic to chicken also. So on the hunt I went.. After researching I found Wellness and Blue Buffalo, they are rated 5 and 6 stars depending on what you chose. all their meat is hormone and steroid free, "fit for human consumption",no by products, no corn, wheat, soy, additives,artifical anything etc. I chose Wellness but Blue Buffalo is also great just a little more expensive but not by much. My pups have been on this canned lamb and on the Wellness supermix dry and I have to say after almost a month they are 100% better.. I will never again feed them major brand/mainstream food again. I couldn't believe purina, Iams, Eukanuba, Science diet were all rated 1 star out of 6, makes you wonder huh.. It is all unhealthy crap! I also got rid of all there store bought biscuits and treats that are filled with the same crap. I purchased healthy treats for them made just like their dog food and I feel so much better and relieved to know I am doing right by my pups..
