Where does it itch when a dog has fleas? - in detail
Flea bites cause localized skin irritation wherever the insects feed. The most common sites include the dorsal neck, behind the ears, along the back, and the base of the tail. These areas have thin fur and skin that are easily reached by fleas, resulting in visible redness and small, raised punctures.
Other frequent locations are the abdomen, inner thighs, and the groin region. The warmth and moisture of these zones attract fleas, leading to concentrated scratching and hair loss. The paws, especially the pads and between the toes, may also show signs of irritation when fleas crawl into the creases.
In severe infestations, the entire coat can become itchy, with generalized redness, scabs, and secondary bacterial infections. Dogs may exhibit:
- Persistent scratching or biting at the skin
- Red, inflamed patches with tiny black specks (feces)
- Hair thinning or loss in affected areas
- Darkened skin due to chronic inflammation
The distribution of itching reflects the flea’s preference for areas where they can remain hidden and feed undisturbed. Prompt treatment targeting these zones reduces discomfort and prevents further skin damage.
