Xiomi 3s has low price so is it given specification are working properly or not should I purchase it considering its specification? Are breed specific dog foods by Royal Canin, Eukanaba, Pedigree, Hills Science any good at all? Many of these are priced high, but the ingredients are majorly corn, wheat, maize, etc. and the protein content is low as well. Is it worth the money or should I stick to N&D dog food only?
