We feed our girl "Diamond Naturals", excellent food at a great price. We tried BB, but the dog's gas was unbearable! We had also tried "wellness" and it was great, but too expensive.
I like Great life the best. It is about $60-70 per bag but it uses freeze dried raw ingredients as well as kibble. Awesome stuff. I have worked at fancy dog stores for 5 years now and have learned a ton about dog food so if anyone has questions, feel free to ask.
