Understand What a Double Coat Actually Is
A double coat has two layers doing two jobs. The soft, dense undercoat traps air for insulation, keeping the dog warm in winter and, counter-intuitively, cool in summer. Over it sit the coarser guard hairs, which shed water and shield the skin from sun and dirt. Breeds like Huskies, German Shepherds, Golden Retrievers, Corgis and Pomeranians all carry this structure.
Deshedding means removing the dead, loosened undercoat without stripping or breaking the guard coat. Get that balance right and the coat looks fuller, sheds less around the house, and regulates temperature properly.
This is different work from clipping a single-coated breed, so if you’re new to grooming tools, ground yourself in the basics with our home grooming guide first.
Work With the Seasonal Coat Blow
Double coats shed heavily twice a year, in spring and autumn, in what groomers call a coat blow. This is when the dog dumps its old undercoat en masse, and it’s the moment to step up your sessions. Trying to force a full deshed outside these windows achieves little, because the undercoat simply isn’t loose yet.
During a blow, short daily sessions beat one marathon. Ten focused minutes a day keeps on top of the loosening fluff without irritating the skin, and it stops drifts of hair colonising your home. Outside the blow, a thorough weekly brush is plenty to keep the coat healthy.
Watch the dog, not the calendar: when tufts start lifting away easily and clumps appear when you rake, the coat is ready and your effort will pay off.
Why You Must Never Shave a Double Coat
It is tempting to think shaving a fluffy dog will cut the shedding and cool it down. It does neither, and it can cause lasting harm. Shaving removes the insulating undercoat and the protective guard hairs together, wrecking the coat’s ability to regulate temperature and exposing pale skin to sunburn.
Worse, the two layers regrow at different rates. The undercoat comes back fast and smothers the slower guard hairs, so the coat often grows back patchy, woolly and a different texture, a problem groomers call coat funk or post-clipping alopecia. In some dogs it never fully recovers.
The only exceptions are genuine medical need, such as surgery or a severely pelted coat that cannot be saved, and those are decisions for a vet or professional groomer, not a summer shortcut. To manage heat, deshed thoroughly and keep the coat clean instead.
Never shave a healthy double coat to reduce shedding or heat. It can cause permanent coat damage and removes the very insulation that keeps the dog cool, leaving skin vulnerable to sunburn.
Master the Undercoat Rake Technique
An undercoat rake reaches down past the guard hairs to pull loose undercoat from the base. Use a light hand: let the tool’s weight do the work and draw it through in the direction of hair growth, in short strokes, section by section. Bearing down or dragging against the grain snaps the guard coat and scratches the skin.
Work systematically along the body, then the trickier areas: the trousers on the back legs, the ruff around the neck, the tail and behind the ears. Follow the rake with a slicker brush to lift the finer fluff the rake leaves behind; a self-cleaning slicker makes emptying the collected undercoat quick between passes.
Check the skin as you go. Pink, comfortable skin means you’re at the right pressure; any redness means ease off and slow down.
Deshed After the Bath and Full Dry
The most effective deshedding happens after a bath and a complete blow-dry. Clean, conditioned hair releases the dead undercoat far more readily, and the force of a dryer physically pushes loosened fluff out of the coat. Brushing a damp, half-dried double coat, on the other hand, risks trapping moisture at the skin and mats forming underneath.
Dry the coat fully to the root first, working through it as you go, then do your final deshed on the dry coat. Our guide to drying a thick coat covers getting right down to the skin. A grooming vacuum such as the Neabot P1 Pro pairs a deshedding attachment with suction, capturing the loosened hair before it fills the room.
Finish by combing through the ruff and trousers to confirm the undercoat is genuinely clear, not just flattened on the surface.

Frequently Asked
A thorough brush once a week keeps a double coat healthy year-round. During the spring and autumn coat blows, step up to short daily sessions to keep pace with the volume of undercoat coming loose.
No. The undercoat insulates against heat as well as cold, so shaving removes the dog's natural cooling and exposes skin to sunburn. A well-deshedded, clean coat cools the dog far more effectively than a shaved one.
An undercoat rake has long teeth that reach beneath the guard hairs to pull out dead undercoat. A slicker has fine bent wires that lift finer loose hair and finish the surface. Use the rake first, then the slicker.
Yes. Pairing a deshedding attachment with suction captures loosened undercoat at the source instead of letting it drift onto floors and furniture. It also helps nervous dogs get used to airflow gradually, though some need time to accept the sound.
