What is coat funk or clipper alopecia?
Last updated 23 September 2026 · How we write and check this
Short answer
Coat funk, also called clipper alopecia or post clipping alopecia, is when a dog's coat regrows unevenly, patchy, or with a different, softer texture after being shaved, most often seen in double coated breeds. It is not painful or dangerous, but the change can be permanent in some dogs.
What it looks like
Instead of the coat regrowing evenly to its previous length and texture within a couple of months, as most shaved coats do, a coat affected by clipper alopecia may stay noticeably shorter, patchy, or fluffier than before, sometimes only in certain areas like the flanks or hindquarters, for many months or longer.
Why it happens
The exact mechanism is not fully understood, but it is thought to involve the hair follicles entering an extended resting phase after the trauma of a close shave, particularly in double coated breeds where guard hairs and undercoat grow on different cycles. It is not linked to a specific product or clipper blade, and it can happen even with careful, professional grooming.
What owners can do
There is no guaranteed treatment, though good nutrition, gentle regular brushing to stimulate the skin, and patience over several months give the coat its best chance of recovering. Since there is no reliable way to predict which dogs will be affected, many groomers advise avoiding a full shave on double coated breeds unless there is a genuine medical need.
Key takeaways
- Coat funk is uneven, patchy, or texture changed regrowth after shaving, mostly seen in double coated breeds.
- It is thought to relate to hair follicles entering an extended resting phase after a close shave.
- There is no guaranteed fix, so avoiding unnecessary full shaves on double coated dogs is the main prevention.
