Folliculitis in Dogs: What Those Skin Bumps Might Mean

Noticed small bumps, pimples, or pustules on your dog's skin? It could be folliculitis - a common skin condition that affects the hair follicles.

What folliculitis looks like:

  • Small red bumps or pimples
  • Pustules (pus-filled bumps)
  • Crusty patches
  • Hair loss in affected areas
  • Itching and scratching
  • Circular lesions

Common causes:

  • Bacterial infection (most common)
  • Parasites (mites, fleas)
  • Fungal infections
  • Underlying skin sensitivities
  • Hormonal imbalances
  • Poor grooming or hygiene
  • Skin irritation from friction

Where it commonly appears:

  • Belly and groin area
  • Armpits
  • Between skin folds
  • Areas where friction occurs

Treatment typically involves:

  • Identifying the underlying cause
  • Medicated shampoos or topical treatments
  • Sometimes oral medications
  • Addressing any underlying conditions
  • Keeping the area clean and dry

If you notice persistent skin issues, it's worth getting a vet's input to identify the cause and appropriate approach.
