Canine folliculitis is common. In fact, you probably know a doggo who has it. So, what is it? Folliculitis is an infection of some type in the hair follicle itself. It can be caused by a very common mite called Dermodex canis. This is the same creature that causes mange. Or, folliculitis can be caused by bacteria like staph or fungi, like ringworm. Sometimes folliculitis is a result of an allergic skin reaction.

What are the signs of folliculitis?

Your short-haired pup may look like she's shedding in circles. Not crop-rings, but small circular patches. It can be trickier to spot in long-haired breeds, but if your doggo is itching its tummy or under its front legs—suspect folliculitis.

Can folliculitis cause discoloration of my dog's skin?

Yes. In fact, short-haired breeds and dogs with light or white coats can exhibit brown or reddish discoloration as a side-effect of folliculitis. Sometimes the discoloration can come from licking the irritated area. If that's the case, it may be time for the "cone of shame."

What else causes folliculitis?

If there's no infection present, your vet may suggest a blood test to see if there's a metabolic culprit. Endocrine diseases, such as hypothyroidism or Cushing's Disease, can lead to folliculitis.

Is canine acne a type of folliculitis?

Sadly, yes. Just like humans, adolescent dogs can develop acne under their chins and around their lips and muzzle. Because it itches, the dog will scratch, open an infected pustule, and spread the infection. Resist the temptation to be Dr. Pimple Popper and see your vet.
