Botflies (Cuterebra) are the primary parasite that lay eggs near a dog's environment, which then hatch into larvae that burrow into the skin, creating a swollen, breathing lump known as a "warble". Other insects, such as house flies, can lay eggs in existing infected wounds, causing maggot infestation.

What lays eggs on dogs' skin?

Does your cat or dog have a Cuterebra or Bot Fly Infection?! Dr. Dan explains.

What happens if a botfly is not removed from a dog?

What does a wolf worm look like on a dog?

Botfly, also known as Cuterebra or wolf worm, is a parasitic infestation in dogs where larvae embed themselves under the skin.

Canines who are limited to the outdoors, have chronic dog skin conditions (but more on this later), open or festering wounds, or mobility impairment are more vulnerable to developing this disease.

What happens if botfly larvae is not removed?

If a botfly larva isn't removed, it typically matures for several weeks to months, creating a painful, boil-like lesion (warble) with a central breathing hole, and may eventually exit on its own; however, incomplete removal or infection can cause serious issues like secondary bacterial infections, severe allergic reactions (anaphylaxis), tissue damage, or, rarely, migration to vital organs (brain, spinal cord, eyes, nasal passages) leading to severe complications or death, so professional removal is always recommended.

What does a warble look like?

Botfly symptoms in dogs often start as a noticeable, swollen lump (warble) on the skin, usually with a small central breathing hole, often appearing on the head or neck, but can also cause lethargy, loss of appetite, sneezing, coughing, nasal discharge, or neurological signs like circling or head tilting if larvae migrate. These lesions can ooze pus or blood, and excessive licking/scratching is common, requiring prompt veterinary care for safe removal to prevent serious infection or systemic issues.
