Where do fleas bite dogs? - in detail
Fleas preferentially target areas of a dog’s body that provide warmth, moisture, and limited grooming access. The most common sites include:
- Neck and base of the skull – thin skin and reduced reach for the dog’s mouth.
- Behind the ears – warm, protected, and often overlooked during self‑cleaning.
- Tail base and dorsal lumbar region – dense fur traps heat and humidity.
- Inner thighs and groin – folds create a microenvironment conducive to flea activity.
- Abdomen and belly button – soft tissue and limited exposure to sunlight.
These locations share characteristics that favor flea feeding: a rich blood supply, minimal hair density, and temperatures around 30–35 °C. Fleas also avoid heavily groomed or highly exposed areas, such as the muzzle or paws, because the dog can more easily remove them. Understanding these preferred bite zones aids in effective inspection, targeted treatment, and prevention strategies.
