Double-coated breeds like golden retrievers, labs, huskies, shepherds, Aussies and corgis need an undercoat rake with long, wide-spaced teeth to pull the fluffy bottom layer, plus a slicker brush to smooth the guard coat and catch stragglers. Single-coated or short-haired dogs (poodles, boxers, pit bulls) do fine with a rubber curry or bristle brush because they don't have that dense undercoat to manage.
Does coat type actually change which tool you need?
Yes. The tool that works for a husky won't do much for a poodle, and vice versa. The difference comes down to anatomy.
Double-coated breeds have two distinct layers. The soft, fluffy undercoat sits close to the skin and traps air for insulation. It sheds seasonally — you'll see massive clouds of fluff in spring and fall when your dog "blows" their coat. On top, longer guard hairs protect against water, dirt and UV. Breeds in this category include golden retrievers, Labrador retrievers, Siberian huskies, German shepherds, Australian shepherds, corgis, Pomeranians, Newfoundlands, Samoyeds and Bernese mountain dogs.
Single-coated breeds have one layer of hair (not fur). That includes poodles, Maltese, Yorkshire terriers, boxers, Dobermans, pit bulls and greyhounds. They shed less dramatically because there's no thick undercoat cycling in and out twice a year.
The tool mechanics that pull loose undercoat fluff (long teeth, wide spacing) are different from the ones that smooth a single layer or collect surface hair (fine pins, rubber nubs). If you use a slicker brush on a golden's undercoat, you'll skim the top and miss the layer that's actually shedding. If you rake a boxer, you're just dragging metal across skin with nothing to grab.
Match the tool to the coat structure, and you'll see less hair on your floor and furniture in the first week.
What tool does a double-coated dog actually need?
A double-coated dog needs at least two tools: an undercoat rake to pull the fluffy bottom layer, and a slicker brush to smooth the guard coat and catch stragglers. Most kits sold separately mean you're buying multiple handles and juggling a drawer full of brushes.
Here's why a slicker alone doesn't work. Slicker brushes have fine, bent-wire pins spaced close together — great for detangling and smoothing the top coat, but they can't reach through 2 inches of dense fluff to the skin. On a golden or husky, the undercoat is where 80% of the loose hair lives. If your brush only touches the guard layer, you're missing the shedding.
The rake goes first. It has long teeth (at least 1 inch) spaced wide apart (0.5 inch or more between pins) so they comb through the undercoat without scraping skin or snagging guard hairs. Two to three minutes with a rake pulls the bulk of the dead fluff. Then the slicker tidies the top coat and grabs any loose hair the rake brought to the surface (1-2 minutes). If your dog has feathering on the legs, chest or tail, a fine-tooth finisher helps smooth those areas without pulling.
That's the 5-minute deshedding routine: rake, slicker, optional finisher pass. SheddyMate's Double Coat Kit gives you all three heads on one handle that twists on and off — undercoat rake, self-cleaning slicker, fine-tooth finisher — so you're not buying three separate tools. It's a founding batch pre-order that ships in 8 to 10 weeks. You can find your dog's setup or order at sheddymate.com.
Which tool for goldens, labs, and other long double coats?
Golden retrievers, flat-coat retrievers and Bernese mountain dogs have a dense, fluffy undercoat with guard hairs that reach 2 to 4 inches. You need an undercoat rake with teeth at least 1 inch long to reach the base without scraping skin, and a slicker for the feathering on legs, chest and tail.
Tooth length matters. If the rake teeth are too short (0.5 inch or less), they'll skim the surface and leave the undercoat packed against the skin. That leads to mats near the base and means you're still sweeping up fluff every day. Wide spacing between teeth (0.5 inch or more) lets the tool glide through thick fur without snagging the longer guard hairs.
Avoid fine-toothed metal combs on these coats — they catch and pull rather than lifting loose fluff. The FURminator is a common alternative, but it uses a fine blade edge to cut through the undercoat. It works, but some groomers worry that pressing too hard or using it too often can trim guard hairs along with the dead undercoat. SheddyMate's undercoat rake uses blunt teeth, not a blade, so it pulls loose fluff without cutting.
After raking, the slicker smooths the guard coat and catches stragglers. Pay attention to the feathering — that's where tangles hide. A quick slicker pass (1-2 minutes) leaves the coat looking tidy and drops the hair you see on your couch by half in the first week.
Which tool for huskies, shepherds, and thick double coats?
Siberian huskies, Alaskan malamutes, German shepherds and Akitas have an extremely dense undercoat with shorter guard hairs (1-2 inches) and heavy seasonal blows. These dogs need a rake with wide tooth spacing — at least 0.5 inch between pins — to move through the density without dragging or pulling.
The undercoat on a husky can be an inch thick and packed so tight that a slicker brush won't penetrate past the surface. That's why you see tumbleweeds of fluff rolling across your floor even after you've brushed. A rake with long, wide-spaced teeth lifts sections of the undercoat away from the skin so the loose fluff can come out. Two to three minutes of raking during a heavy blow can fill a grocery bag.
After raking, a slicker collects the loose hair you've brought to the surface and smooths the guard coat. Some owners add a fine-toothed finisher or comb for the underline, tail and behind the ears — areas where mats form fast during shedding season.
Do not shave a double-coated dog. Shaving destroys the insulation system (cool in summer, warm in winter) and can cause uneven regrowth or damage the guard coat permanently. Even a close trim messes with the coat's ability to regulate temperature. If you're overwhelmed by shedding, more frequent brushing is the answer, not clippers.

What about single-coated or short-haired breeds?
Single-coated and short-haired breeds don't need an undercoat rake because there's no undercoat to pull. A bristle brush, rubber curry or grooming mitt removes dead hair and distributes natural oils without dragging metal teeth across skin.
Single-coated dogs like poodles, Maltese and Yorkies grow hair (not fur) in one continuous layer. They shed lightly and don't blow their coat seasonally. A slicker brush works well for longer single coats (poodle mixes, shih tzus) to prevent tangles, but you don't need a rake. For these breeds, regular trimming matters more than deshedding tools.
Short-haired dogs like boxers, Dobermans, pit bulls and greyhounds have a single layer of short, smooth fur. They still shed — you'll see fine hairs on your clothes and couch — but the volume is much lower than a double coat. A rubber curry (the kind with soft nubs) or a bristle brush lifts dead hair during a weekly once-over. Pressing the curry in small circles loosens the hair so it comes off on the brush instead of your furniture.
One common confusion: Labradors are double-coated and shed heavily, even though their guard hairs are short. A lab needs an undercoat rake just like a golden. Boxers are single-coated and shed lightly. Same short-hair look, completely different tool needs.
How do I know if I'm using the wrong tool?
You're using the wrong tool if you're brushing daily but still see tumbleweeds of fluff, the brush only catches surface hair, your dog's coat looks puffy or matted near the skin, or you're pressing hard and your dog pulls away.
Sign one: You brush for 10 minutes and pull off a handful of hair, then an hour later there's fluff all over the couch again. That means the tool isn't reaching the undercoat. On double-coated dogs, the dead fluff sits deep. A slicker or bristle brush will skim the top and leave 80% of the shedding hair packed against the skin. Switch to a rake first, then slicker.
Sign two: The coat looks smooth on top but feels dense and spongy when you press your hand against your dog's side. That's matted undercoat. The guard hairs are lying flat, but underneath, dead fluff is felting into a layer that traps heat and moisture. An undercoat rake with long teeth will lift that layer out in clumps.
Sign three: Your dog flinches, scoots away or snaps when you brush certain areas. You're either pressing too hard (the teeth are scraping skin instead of combing through fur) or the tool is snagging and pulling. Check that the rake teeth are blunt, not sharp, and that you're brushing in the direction of hair growth with light, even strokes. If the tool is right and your dog is still sensitive, shorten your sessions — 2 minutes of gentle raking beats 10 minutes of wrestling.
Sign four: You've tried three different brushes and nothing reduces shedding. The issue might not be the tool; it might be health-related. Excessive shedding, bald patches, red or flaky skin, and hot spots are reasons to talk to your vet before buying another grooming kit.
For SheddyMate, there's a 30-day less hair guarantee. If you're not seeing less hair on your floor and furniture after a month of the routine, return it. The point isn't to own the right tool; it's to actually reduce the hair you're cleaning up every day.
Frequently Asked Questions
What deshedding tool is best for a golden retriever?
Golden retrievers have a thick double coat with a fluffy undercoat and long guard hairs. You need an undercoat rake with teeth at least 1 inch long to pull loose fluff from the base, plus a slicker brush to smooth the top coat and catch stragglers. Most owners see the biggest drop in shedding when they rake first, then slicker.
Can I use the same brush on my husky and my boxer?
No. Huskies have a dense double coat that needs an undercoat rake to reach the fluffy bottom layer. Boxers have a short single coat with no undercoat, so a rubber curry or bristle brush is enough. Using a rake on a single-coated dog won't hurt, but it won't do much because there's no undercoat to pull.
Why is my slicker brush not reducing shedding?
Slicker brushes have fine pins that smooth the top coat, but they don't reach the dense undercoat on double-coated breeds like goldens, labs or shepherds. If you're only using a slicker, you're missing the layer that sheds the most. Add an undercoat rake to your routine — rake first to pull the deep fluff, then slicker to tidy up.
Do I really need three different tools for my dog?
For heavy-shedding double coats, yes — an undercoat rake, a slicker, and optionally a fine-tooth finisher give you the best results. Most kits force you to buy separate handles for each. SheddyMate's Double Coat Kit puts all three heads on one handle that twists on and off, so you're not juggling a drawer full of brushes.
Is the FURminator safe for double-coated dogs?
The FURminator uses a fine blade edge to cut through loose undercoat. It works, but some groomers caution that pressing too hard or using it too often can trim guard hairs. SheddyMate's undercoat rake uses blunt, wide-spaced teeth that pull loose fluff without cutting, which is gentler for dogs with sensitive skin or long guard coats.
What tool should I use for a corgi or Australian shepherd?
Corgis and Aussies are double-coated and shed year-round, with heavy blows in spring and fall. Use an undercoat rake to pull the fluffy bottom layer (2-3 minutes), then a slicker to smooth the guard coat and catch loose hair (1-2 minutes). A fine-tooth finisher helps on feathering around the legs and tail if your dog tolerates it.
