Mats appear overnight, your dog bolts when the brush comes out, and fur ends up everywhere except the brush. The fix is a slicker brush with pins long enough to reach the undercoat without scraping the skin — the right one turns a battle into a bonding session. Here are nine options for long-haired dogs, judged on pin length, gentleness, and how easy each is to clean.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Long coats need pins that reach deep without tugging, so we matched every pick to the best brush for long hair dogs, from budget-friendly single tools to complete grooming kits that professionals actually use.
Our Picks at a Glance
How To Choose The Best Brush For Long Hair Dogs
The biggest mistake owners of long-haired dogs make is grabbing a brush meant for short coats. Those fine, dense pins skim the surface and never touch the undercoat where mats form. You need pins long enough to reach down through the topcoat to the skin — but gentle enough that the dog doesn’t feel stabbed.
Pin Length and Angle
Long pins (around 1 inch or more) are the whole game for doodles, shepherds, and similar breeds. They penetrate deep to lift dead undercoat hair before it tangles. The angle of the pins matters just as much — many quality brushes bend pins at a curve (some at 135 degrees or 140 degrees) so the tip glides through fur rather than jabbing straight in. A curved pin angle lets the tip glide through fur instead of jabbing, which is why dogs tolerate curved pins far better than straight ones.
Self-Cleaning vs. Manual Cleaning
Long hair clings to pins stubbornly. A self-cleaning slicker has a push-button that retracts the pins into the pad, letting you wipe the fur off in one motion. Others require a comb or dedicated cleaning tool to lift trapped hair. If you value speed, the retractable design saves real time after every session.
Handle and Grip
Grooming a thick coat takes minutes, not seconds. A handle with a soft-touch or rubber grip reduces hand fatigue during longer sessions. Some premium options use contoured solid wood, which feels sturdy and gives you control even when the dog is wiggling.

In-Depth Reviews
1. The Doodle Brush Slicker Brush
Our pick — over 4.5★ from 950+ verified ratings; the strongest balance of quality and price.
The gentlest long-pin slicker for doodles that hate being brushed
The defining feature here is the extra-long nylon pins that reach deep into a dense curly coat without scraping the skin beneath. That is the exact combination owners of Goldendoodles, Cockapoos, and Poodles struggle to find — and it shows in how the brush performs on stubborn mats. The pins work so gently that dogs who previously resisted grooming sit still through even ear-mat removal.
The build quality is the most-praised feature, with functionality a close second. The ergonomic rubber-coated plastic handle keeps your hand comfortable during longer sessions, and the oblong shape fits naturally in your grip. It handles every coat type from tight curls to the thick double coat of a German Shepherd mix, right up to a Caucasian Shepherd.
Buyers report that it removes tangles without causing pain, which is the whole point for sensitive-skinned breeds. The nylon bristles are strong yet soft enough that a 28-pound cockapoo (a size that initially seemed too large for this brush) takes it without complaint. One owner sums up the experience: “My doodle had been resistant to letting me work on his coat. This slicker brush works very gently, even when removing a mat on his ears.”
What Owners Love
- Extra-long pins reach deep without pain
- Works on all coat types from curls to double coats
- Ergonomic handle reduces hand fatigue
- Eco-friendly construction stands out
Keep in Mind
- No self-cleaning mechanism — you’ll need a comb to clear pins
- Plastic handle won’t match the feel of solid wood
Reach for this if: your dog has a sensitive-skinned curly or double coat and runs from every other brush you’ve tried — the gentle long pins solve the exact problem.
Think twice if: you want one-hand cleanup after every session; this one needs a separate tool to lift trapped fur from the pins.
2. WAHL Premium Large Pet Slicker Brush
The budget slicker that handles very thick coats without flexing
WAHL built this one specifically for medium and long coats, and at just 4 ounces it stays light enough for everyday use while the soft-touch rubber grip keeps your hand comfortable. The large 8-inch-wide head covers a lot of ground per stroke, which matters when you’re working through a thick poodle or bichon coat.
Owners mention it works well on thick long dog hair and is easy to clean and use, with the caveat that the bristles aren’t the softest — acceptable for very thick hair but not ideal for delicate skin. The lasting durability is the real story here: it holds up for a year plus when other brushes fail in a few months, and the large size fits a hand well for one-handed daily grooming.
A poodle owner notes their dog falls asleep during grooming, which tells you the bristles are less harsh than the competition even if they’re not pillow-soft. It’s specifically praised for long or matted coats on poodles and bichons, and owners warn it’s not the tool for short-coated breeds. Use it gently from tips to roots and it earns its spot as the budget pick that punches above its weight.
Sturdy Daily Driver: this is the reliable, no-nonsense choice for owners with very thick long coats who want a large, durable brush without spending for a premium brand.
The Trade-Off: softer bristles matter to some — this one prioritizes strength over silkiness, so very sensitive dogs may prefer the Doodle Brush above.
3. Hertzko Self-Cleaning Slicker Brush
The push-button slicker that makes cleanup take five seconds flat
The entire reason this brush exists is the self-cleaning mechanism — a push-button retracts the bristles into the pad so you can wipe the collected fur off in one motion instead of picking it out pin by pin. That single feature is why it’s the crowd favorite for shedding control, and it works with one hand, which owners genuinely appreciate when the other hand is holding a wiggly dog.
The angled bristles detangle and remove shedding fur while massaging the skin, and the fine construction is gentle enough for both long and short-haired pets. The comfort-grip handle minimizes hand fatigue during extended sessions.
Customers note it suits long-haired dogs and cats, which purr during use. The sharp bristles need caution but detangle well and prevent matting. The honest trade-off: a Pomeranian owner notes it’s “a good one, but not so ‘easy to use’ as advertised. If it is a Pomeranian, it’ll take a lot of time and effort.” Dense double coats still demand patience, but the cleanup convenience is class-leading.
The Big Win
- Retractable bristles for instant fur removal
- Usable one-handed during grooming
- Gentle fine bristles work on all fur types
- Angled pins massage skin while detangling
The Honest Catch
- Very dense coats like a Pomeranian still take time and effort
- Sharp bristles need careful handling
Pick this for: the convenience of one-hand cleanup — if you groom daily, the retractable bristles save you the most annoying part of the job.
skip it if: your dog has an extremely thick double coat like a Pomeranian and you’re expecting a quick fix; it helps but won’t short-circuit that job.
4. Werduoland Wooden Slicker Brush Set
A three-tool kit built around a 140-degree curved slicker head
This set gives you the slicker brush plus a wide-and-narrow teeth comb and a 2-in-1 detangling handle comb, so you can groom the topcoat and undercoat in one session without juggling separate purchases. The slicker itself has a 140-degree curved surface that follows your dog’s natural shape, plus over 270 stainless steel needles at 25mm long that penetrate deep without tugging or scratching.
The build quality is the top praise, with hair removal close behind — the long, dense, soft pins reach the coat base and prevent matting in doodles and double-coated dogs. At 8.4 ounces it has a real presence in the hand, and the wooden handle feels comfortable and sturdy. The rounded teeth are soft on skin, which is why reviewers point out their dogs think grooming is a massage.
Shoppers say it’s gentle on sensitive areas and soft on a poodle’s skin, with one noting the dual-width metal comb is great for detangling and undercoat work. The honest caveat: the flea comb in the set can lose teeth, which is common for that tool type. But the slicker itself earns comparison to pricier doodle-specific brands and comes out ahead.
Kit That Covers Everything: if you’re starting from scratch, this gives you the brush, a detangling comb, and a topcoat comb — the full daily toolkit.
The Small Flaw: the flea comb loses teeth over time; treat it gently and the rest of the set holds up beautifully.
5. NeatHoiho Large Slicker Brush & Comb Kit
Pins bent at 45 degrees that reach deep into curls without scratching
Each pin here is about 1 inch long, bent and angled at roughly 45 degrees so it won’t scratch your dog’s skin while still reaching down into the undercoat. The retractable cushion pad adds another layer of protection, flexing as you brush so the pins don’t dig in. Combined with the included anti-static stainless steel comb, this is a two-tool system for curly coats like Goldendoodles, Poodles, and Schnauzers.
Buyers consistently praise the build quality and how well the angled pins detangle without scratching. Buyers report the gentle bristles are soft enough not to bother dogs — a Husky owner finds it works particularly well, and cats with dense coats stay engaged longer because the longer bristles mean fewer cleaning stops. The slip-resistant grip reduces strain on your hand, wrist, and arm during longer sessions.
The metal comb’s round teeth break up tangles and lift loose hair, dander, and dirt trapped beneath fur. What some owners note is the appearance and material get mixed reactions — it’s not the prettiest tool and the construction draws occasional comment, but the function holds up. For a doodle puppy with a transitioning coat, owners mention it saves real effort versus other brushes.
Why It Works
- 1-inch pins at 45-degree angle reach deep safely
- Cushion pad flexes to protect skin
- Included anti-static comb tackles trapped dirt
- Slip-resistant grip reduces wrist strain
Minor Notes
- Appearance and material get mixed reactions
- Some owners comment on the construction quality
Reach for it when: your dog has tight curls or a dense coat that tangles fast — the angled long pins and cushion pad do the heavy lifting.
The small caveat: looks aren’t this kit’s strong suit, so if presentation matters to you, the wooden-handle options above have more polish.
6. COZYGIFT Wooden Slicker 3-in-1 Kit
A grooming kit engineered to stop skimming topcoats on shedders
This set is built around one idea: reach the dense undercoat of Doodles, German Shepherds, and Golden Retrievers to pull out dead hair and restore fluffiness. The extra-long flexible wire pins curve at a precise 135-degree angle, so they slide through the topcoat and into the undercoat without scraping sensitive skin. The solid wood handle keeps it comfortable through longer deshedding sessions.
You get three pieces: the high-density slicker, a dual-spacing stainless steel comb for fine fur around ears, eyes, and paws, and a dedicated wooden cleaning rake that slides through the pins to lift trapped hair. That third tool is rare and genuinely useful — it keeps the brush hygienic and prevents pin bending over time. Owners highlight the sturdy build and strong bristles that handle thick coats without bending.
Customers note a Golden Doodle that actually enjoys grooming time, and a Great Pyrenees owner calls the flea comb the best ever — long wooden handle, rounded end for crushing fleas, and it thins fur effectively. Groomers approve it for thick coats on Doodles, Pyrenees, Saints, and Samoyeds. The prongs look sharp but flex rather than scratch, making brushing comfortable for the dog and easier for you.
Undercoat Specialist: the 135-degree curved pins plus the cleaning rake make this the most complete deshedding kit for double-coated breeds.
Know Before You Buy: it’s a 3-piece system, so it takes a little more storage space than a single brush — worth it for the coverage.
7. Freshly Bailey Doodle Slicker Brush
The detangler that fluffs up coats without pulling hair out
The long, fine, hooked pins here are designed to work through dense and curly coats — Goldendoodle, Husky, Poodle, Bernedoodle, Australian Shepherd — removing mats and undercoat without yanking. It’s built to be less abrasive and more comfortable, which is why owners of dogs that usually hate brushing report a change in attitude. The large head gives good coverage per stroke, so you spend less time per session.
The effectiveness is what wins people over: it removes tiny knots and tangles without pulling hair out, leaving coats soft and smooth. A double-coated Chow/Pit/Heeler mix owner found it durable, with the fine hooked pins untangling without pulling and the dog staying comfortable throughout. A Shih-poo owner confirms it fluffs up the hair and does a good job detangling, with the dog not minding at all.
Reviewers point out it works perfectly for Goldendoodles, and one owner who went through five different brushes calls this the perfect one — bristles not too sharp, gets mats and tangles out, and the dog finally enjoys brush time. The honest trade-off: it’s a bit harder to clean, as fine hair remains trapped in the pins, and it’s pricier than basic slickers, though owners say it’s cheaper than comparable high-end brands.
Why It Wins
- Fine hooked pins detangle without pulling
- Large head covers more coat per stroke
- Comfortable enough for dogs that hate brushing
- Outperforms more expensive comparable brands
The Catch
- Harder to clean — fine hair stays trapped in pins
- Premium price tier for a single brush
Choose this when: your dog’s coat tangles constantly and you’ve tried multiple brushes already — the hooked pin design solves the pull problem.
Be ready for: a little extra time cleaning the pins after each use, since there’s no retraction button here.
8. KIZO ESLO XL+ Undercoat Rake
The two-sided rake that strips out undercoat on giant breeds fast
This isn’t a slicker — it’s a rake with a distinctive 2-sided hooked-blade head: wide teeth for stubborn mats on one side, fine teeth for deshedding on the other. The XL head covers more coat per stroke and lifts trapped undercoat with fewer passes, which is exactly what you want for a German Shepherd, Husky, Great Pyrenees, or Bernese Mountain Dog during shedding season.
Owners overwhelmingly praise how effectively it strips out undercoat, with shedding reduction a close second. A show-class German Shepherd owner says after 10 minutes of brushing there was a huge difference in appearance, and a Bernese Mountain Dog owner bought a second rake so two people could groom at once. The smooth, rounded stainless-steel edges glide through fur with less pulling and scratching, and the contoured solid-wood grip feels comfortable and easy to hold.
Shoppers say it’s durable — one notes it hasn’t broken after multiple uses and calls it “the best undercoat rake” on a large mixed breed, with the coat feeling soft and silky with regular use. Even small dogs with medium-long hair (Coton du Tulear, Havanese) benefit when used gently. The lifetime warranty from KIZO ESLO backs the build, so the price buys long-term confidence.
The Big Guns
- Two-sided head: wide teeth for mats, fine teeth for shedding
- XL head covers more coat per stroke
- Rounded edges glide without scratching
- Lifetime warranty against defects
The Right Fit
- Premium price — but it’s a heavy-duty tool, not a daily slicker
- Not for tight mats — never force it through a knot
Get this for: heavy shedders and giant double-coated breeds where a slicker alone can’t keep up — the rake lifts what the brush misses.
It’s not for: daily maintenance on a lightly-shedding dog; this is the seasonal shedding-season workhorse.
9. Poodoodle Large Slicker Brush
The air-cushioned brush with double the pins for a massage-like groom
The headline spec is the 1-inch long bent pins that glide through tough tangles and mats, paired with an air-cushioned pad holding double the pins of a standard slicker. That combination means more contact per stroke and a soothing, massage-like experience that keeps dogs calm and comfortable. It’s engineered specifically for poodles, goldendoodles, labradoodles, and cockapoos.
A professional groomer with 20 years of experience praises it for thick, double, and curly coats — calling it sturdy, large, lightweight, and saying it performs like brushes in the higher price tier. The wood handle and stainless steel bristles give it a premium feel at a mid-range price. Buyers report their Shih-Poo sits still through grooming and their Golden Doodle doesn’t fight the comb anymore.
The honest trade-off: there’s no hair-release button, so you’ll need a separate metal comb to clear trapped hair from the pins — one owner notes it works well but requires that second device. It removes knots and snowballs painlessly and reduces shedding while reaching the undercoat. For a dog with very thick hair like a Pomeranian or a poodle, owners mention it does a great job where other brushes fell short.
The Strength
- 1-inch bent pins detangle without pulling
- Double-pin air-cushioned pad massages while grooming
- Professional-groomer quality at mid-range price
- Lightweight despite large size
The Requirement
- Needs a metal comb to clear hair from pins
- No self-cleaning mechanism
Go for this if: you want professional-grade detangling for curly and thick coats without paying professional-tool prices — the double-pin pad is the differentiator.
Keep a comb nearby: this one expects you to bring your own cleaning tool, so factor that into your grooming kit.
Understanding the Specs
Pin Length and Curve
The single most important spec for long-haired dogs is pin length — look for pins around 1 inch or longer so they reach the undercoat where mats form. The curve angle (often 135 or 140 degrees) determines how gently the pin enters the fur. A sharper angle means the tip slides along the coat rather than stabbing into the skin, which is why dogs tolerate curved pins far better than straight ones. Always match pin length to your dog’s coat depth, not their body size.
Self-Cleaning vs. Standard Pads
Long hair clings to pins aggressively, so cleaning mechanism matters more than most buyers expect. A self-cleaning brush retracts the pins into the pad with a button, letting you wipe fur off in one swift motion. Standard brushes require a separate comb or rake to lift trapped hair. The trade-off is that retractable mechanisms can feel less sturdy, while fixed pads often hold more pins and feel more solid for heavy detangling work.

For most owners of long-haired dogs, the brush for long hair dogs winner is the The Doodle Brush Slicker because its extra-long pins detangle sensitive-skinned curly and double coats without causing pain — the single hardest problem in this category. If you want self-cleaning convenience for daily touch-ups, grab the Hertzko. And for heavy shedders with dense double coats, the KIZO ESLO Undercoat Rake is the one to reach for when shedding season hits.
