Diesel has struggled with this his whole life. It comes and goes, but when it gets really bad they will break open and bleed and I feel so bad for him. I have talked to many vets about this and they ALL give different opinions. One told me to dab Listerine on the breakouts, another told me to dab tea tree oil on them. He HATED both these and had a viceral response to it, not to mention neither method did any good. I tried switching foods to avoid wheat and oatmeal, didn't make a difference. Another vet put him on an antibiotic because he had a bladder infection, and that cleared it up right away, but when the meds were gone, the acne came back. I use a stainless steel bowl, I wash it constantly, I wipe his chin off after meals with puppy wet-wipes, NOTHING makes a difference. Then another vet most recently suggested a doggy grade acne pad and to see the clinic's dermatologist. So it remains to be a battle for us.
Sometimes they are huge red bumps that take weeks to clear up, other times they look just like a human's pimple. Right now he has a mild break out, but it seems like it gets the worst in the winter time.
