Hi Amanda, welcome to you and Ellie to EBN. Pink face and acne can be symptoms of food allergies. If you haven't already, you should read the pet food ratings on the home forum. It lists all the pet foods and rates them from 1 Star to 6 Star. You want to choose a 4 Star or higher brand of dog food. Examples of these foods brands are Wellness, Blue Buffalo, Orijen, and Fromm's. Pro Plan unfortunately is not rated as a good food. A lot of EB are allergic or sensitive to chicken, and sometimes salmon, and grains, or corn, so if your present food contains these ingredients they could be causing his symptoms.
