by the ingredents list bil-jac looks the worst, and canadae looks to be the best. Annamaet looks pretty good, but has a lot of grains right at the top of the list, that would turn me off right there. I dont like the bil-jac ingredience because of the very first ingredient. I would have to say it gives dogs a shiny coat because one of the ingredence is eggs lol which well gives dogs a shiny coat...
