We have 3 dogs in our house of varying ages: one senior citizen, one young adult, and a puppy that is almost a year old. Because they are small breed dogs, they graze throughout the day rather than eat all at once, so we had to find a food they could all share. Our senior had skin issues and hot spots, the young adult male had a sensitive tummy, and the puppy needed good nutrition to keep her active as she transitioned from puppy food to adult food. We'd tried more expensive brands in the past, but nothing seemed to work for everyone... and then we found this! An employee recommended Iams Sensitive Naturals as a grain-free food that is on par with more expensive brands. We gave it a shot and have not looked back since! The skin and tummy troubles cleared up, everyone has shiny coats and lots of energy! For the price, you cannot beat it. The most sensitive of stomachs can tolerate this well and our vet approved it as nutritionally solid. It comes in various sized bags and is generally easy to find (Target, PetSmart, Publix) too. Love it!
