LipomasĪlthough these are commonly referred to as “fatty tumors,” they are benign, not malignant. If a sebaceous cyst is particularly messy or in an area where it constantly becomes irritated, it can be surgically removed. Sebaceous cysts will sometimes open and ooze their contents on their own, or the material can be squeezed out, but usually they will simply fill up again over time. They contain a whitish, greasy, paste like combination of oil, bacteria, and skin cells. These lumps are oil producing (sebaceous) glands that have become blocked and enlarged, ranging from mosquito-bite-sized to an inch or two in diameter. Pimples or blackheads elsewhere can be a symptom of a bacterial skin infection or seborrhea. Facial acne in dogs usually responds well to frequent cleaning with a benzoyl peroxide cleanser. Pimples and black headsĭogs can get “clogged pores” just like people do, and these may form pimples or blackheads. These should be surgically removed if they routinely bleed or become irritated, or if they grow on the eyelid margin and rub against the eye. Older dogs often grow warts on their heads or bodies – but these are not viral in origin, and may not actually be “warts” on biopsy as many are sebaceous adenomas. “Puppy warts’ are caused by a virus, appear in or around young dog’s mouth, and go away on their own. These firm, bumpy growths occur in both young dogs and middle aged to older dogs. No growth can be definitively diagnosed by its appearance alone, however, so point out such lumps and bumps to your veterinarian during your dog’s annual physical exam, and be sure to consult your vet if your dog has a lump that grows rapidly, oozes and doesn’t heal, or otherwise bothers you or your dog. Here is a guide to some typical skin growths in dogs. Fortunately, most are merely unsightly or messy rather than harmful. Dogs can sprout a variety of lumps, bumps, and skin growths, especially as they get older.
