1. Get rid of plastic food dishes.
Hot spots around the face can be caused by plastic food bowls. Throw out your plastic food and water bowls. Plastic tends to develop tiny cracks that can harbor bacteria, which cause reactions in sensitive dogs and cats.
Pets that are sensitive to these plastic food bowl bacterial allergens often develop puppy acne or feline acne and a rash or pimples around the lips and chin, and sometimes even around the eyes or ears.
Replace plastic with stainless, glass or ceramic food bowls and keep them meticulously clean, including washing them in the dishwasher at least weekly.
