When I got Biscuit, he came with a box of Purina. Thankfully it was a small box and when it was nearly empty I did my research and started feeding him quality food. We tried an expensive brand, Wellness puppy, that was not part of the big recall, and it was good. However, after many months on that, I asked my local pet boutique owner for recommendations and she opined that Wellness puts too much $$ into the fancy bags, and she recommended Evo, which is a much higher protein food. I started with the poultry small bites flavor, and Biscuit liked it. I switched to the red meat small bites, for variety, and he really loves that one. It is pricey, especially in San Francisco, but I feed him less, because it is so nutrient/protein dense. My sister feeds her mini schnauzer Royal Canin, which has different formulations for different breeds, and she is happy with it.
