I feed both of mine Merricks Puppy Plate. Before coming to YT, I fed Science Diet because I thought it was a great food. After doing lots of research and chatting on YT, I learned that maybe it isn't the best possible food I can be feeding. (It is full of lots of fillers) I used the website
Dog Food Analysis - Reviews of kibble to compare foods. I decided on Merricks because it was a popular choice among YTers, it recieved great reviews on the above website, I personally have tasted ALL of the main ingrediants, and I am able to find it here in town.
