i gave milu eukanuba food when i first got her, because that's what the breeder recommended, but i have since done research and realized that most commercials foods are really bad quality foods for your doggie.
right now i am feeding milu nature's variety raw medallion. you can check out their website for more info if you are interested.
Nature's Variety
i recommend doing your own research to find out for yourself what you think is best.
there are a lot of threads in the diet/heath sections about dog food. you can browse and search there to get your feet wet.
