    If you went through the pimple-and-whitehead stage as a teenager, you probably empathize if your dog is getting them. It's not the same thing for your dog, though. For one thing, he's not worried what other dogs think if a zit sprouts. Your vet can help you treat canine acne.

    Just like humans, dogs tend to develop acne in the equivalent of their teen years. For canines, that means about the ages of 5 months to 8 months. It generally occurs on the muzzle or chin. By the time the dog reaches his first birthday, odds are his zits are gone. Affected dogs have whiteheads and blackheads. Don't try to squeeze your dog's pimples. Take him to the vet to rule out other issues instead. Certain skin conditions look like acne but are far more serious.

    Dog acne usually results from folliculitis, or inflammation of the hair follicles. Besides whiteheads, dogs with folliculitis might experience small ulcerated sores, which often itch. If the follicle ruptures, your dog could end up with furunculosis, similar to boils in people. Just as with people, severe cases of canine acne or folliculitis can leave scarring. While fairly rare in long-haired dogs, certain breeds, including boxers, bulldogs, Rottweilers, mastiffs, Great Danes and Doberman pinschers, are often affected.

    Your vet will prescribe a topical cleaner and disinfectant, such as benzoyl peroxide. You may use a product with this active ingredient yourself, but don't put it on your dog. His skin is much thinner and more sensitive than yours, so using benzoyl peroxide designed for humans will irritate it. Use the doggie version your vet prescribes. If his skin is badly infected, your vet might also prescribe antibiotics. She might also recommend using special soaps or medicated wipes to wash affected areas.

    Even though it appears your dog has acne, your vet should take skin scrapings just to make sure it isn't another condition. Canine dermatological problems that resemble acne include demodetic mange, the Malassezia yeast infection, seborrhea, contact allergic reactions, autoimmune diseases and even cancer. Another issue is pyoderma, or pus in the skin. According to The Merck Veterinary Manual, over-growth of the normal bacteria on the dog's skin usually triggers this infection. A pyodermal infection can go quite deeply into the dog's body compared with a superficial infected hair follicle.
