Grooming and coat
Why does brushing sometimes irritate my dog's skin?
Last updated 23 September 2026 · How we write and check this
Short answer
Usually the brush itself is the problem rather than brushing in general. A wire slicker pressed too firmly, used on thin skinned areas, or dragged over the same spot repeatedly can leave skin red or lightly scraped, sometimes called brush burn. Lightening your pressure and switching tools on sensitive areas usually fixes it within a session or two.
What brush burn looks like
A patch of skin that looks pink, feels slightly warm, or shows tiny scrape marks after a session is most common on the belly, inner thighs, and armpits, the spots where skin sits close to the surface with little coat to cushion fine wire pins. It usually follows a longer session done at full pressure rather than a light touch.
Technique changes that help
Letting the brush's own weight do the work instead of pressing down, and passing over each section only two or three times before moving on, cuts the friction that causes irritation. On thinner skinned areas, switching to a rubber curry brush or a rounded pin brush removes the fine wire pins from the equation entirely.
Giving irritated skin a rest
A spot that is already red benefits from a day or two without brushing, with a damp cloth used instead to keep loose hair down. Skin that stays red, swells, or clearly bothers the dog past a few days of rest is worth having a vet look at rather than waiting for it to settle on its own.
Key takeaways
- Brush burn usually comes from too much pressure or too many passes with a wire slicker, not from brushing itself.
- The belly, inner thighs, and armpits are the most common spots because skin sits close to the surface there.
- A rubber curry brush or rounded pin brush is a gentler choice on thin skinned areas.
