Itchy skin is something many pug owners deal with. Red patches, constant scratching, and even hair loss often come from food sensitivities. Choosing the best grain free dog food for skin allergies can ease those flare-ups and help your pug’s coat stay soft and healthy.
It’s worth noting that not all allergies come from grains. Some pugs react more to proteins like chicken or beef. Grain free diets, especially those with limited ingredients, are helpful when wheat or corn are the triggers—but protein rotation can sometimes be just as important.
Not every grain free recipe is the same. Some are simple and affordable, while others are carefully made with limited ingredients or nutrient-rich air-dried blends.
