TL;DR
Grooming a double-coated dog like a Husky or Great Pyrenees requires a two-step approach: removing loose surface hair and extracting the dense, woolly undercoat. After evaluating the most popular tools, the Hertzko Self Cleaning Slicker Brush stands out for daily maintenance and surface deshedding because of its convenient hair-release button. However, for deep undercoat removal and tackling tough mats, the Safari Dematting Comb and specialized rakes are far more effective. While Hertzko is excellent for shorter-haired double coats or finishing work, Safari tools are built for the heavy lifting required during “blowing coat” season. For owners of dogs with exceptionally thick coats, we found that professional-grade alternatives like Chris Christensen slickers often outperform both brands in terms of pin length and durability.
After years of grooming dogs with coats thick enough to hide a TV remote, I have learned one hard truth: a standard brush often just slides over the top of the problem. If you own a Golden Retriever, a Samoyed, or a German Shepherd, you aren’t just managing hair; you are managing a complex ecosystem of guard hairs and a dense, insulating undercoat. When that undercoat gets trapped, it forms mats that can pull on your dog’s skin and cause significant discomfort.
Choosing between Hertzko and Safari usually comes down to whether you are doing a quick daily tidy-up or a deep-dive grooming session. In my experience, most owners end up needing a bit of both. We’ve analyzed these brands based on real-world use, Reddit feedback from professional groomers, and hands-on testing to see which one actually reaches the skin.

Understanding the Double Coat: Why Your Brush Choice Matters
Double-coated dogs have two distinct layers. The outer layer consists of “guard hairs” that repel water and dirt. Beneath that lies the undercoat—a soft, downy layer that regulates temperature. This undercoat sheds heavily, usually twice a year, in a process often called “blowing the coat.”
Standard pin brushes with those little plastic balls on the ends are arguably the worst choice for these breeds. They tend to snag on the undercoat and pull the hair rather than gliding through it. To properly groom these dogs, you need a slicker brush with fine, bent wire pins (like the Hertzko) or a rake with sharpened blades (like the Safari) that can actually penetrate the density of the coat. If you are also dealing with seasonal issues, check out our comparison of Hertzko vs Safari for dogs with allergies to see how different bristles impact dander levels.

The Contenders: Hertzko vs. Safari Grooming Tools
Hertzko Self Cleaning Slicker Brush
The Hertzko slicker is often the first tool recommended for new owners of double-coated breeds because it solves the messiest part of grooming: getting the hair out of the brush. With a single click, the bristles retract, leaving a neat disc of fur you can simply toss in the trash. In my testing, this mechanism is robust and saves about five minutes of picking at wire pins per session.
However, the convenience comes with a trade-off. The pins are relatively short and stiff. While this is perfect for a Golden Retriever’s feathering or a Pomeranian’s topcoat, it may struggle to reach the skin of a Great Pyrenees or a thick-necked Akita. It effectively grabs loose hair on the surface but isn’t a deep-cleaning tool for heavy matting.
The Good
- The retracting button makes cleanup effortless and prevents bent pins.
- The handle is thick and rubberized, reducing hand fatigue during long sessions.
- Gentle enough for daily use without irritating the skin if used with a light touch.
The Bad
- The pins may be too short to penetrate the dense undercoat of giant breeds.
- The internal spring mechanism can occasionally stick if fine dander gets inside the housing.
- It is bulkier than traditional slickers, which makes grooming small areas like armpits difficult.
Our Take: Best for owners of moderate double coats like Goldens or Labs who need a reliable daily brush. Skip if your dog has a 4-inch thick undercoat that hasn’t been brushed in months.
Safari Dematting Comb
When the Hertzko slicker meets a mat it can’t handle, the Safari Dematting Comb steps in. This tool doesn’t just brush; it uses sharpened stainless steel blades to slice through tangles. For double-coated dogs prone to “ear mats” or “britches mats” (around the rear), this is a essential piece of equipment. You use it with a picking motion rather than a long pulling stroke.
One thing I noticed immediately is that Safari’s build quality is utilitarian. It doesn’t look fancy, but the blades hold their edge for a long time. Because the blades are sharp, you must be extremely careful around skin folds. It is a precision tool, not a general-purpose brush.
The Good
- Saves the coat by slicing mats instead of pulling them out by the root.
- Reversible blade assembly allows it to be used by both right and left-handed owners.
- Far more effective at reaching the “skin-level” undercoat than a slicker brush.
The Bad
- The blades are genuinely sharp; improper use can result in “brush burn” or small nicks.
- It can thin out the coat too much if used too frequently in the same spot.
- The handle is somewhat thin compared to the Hertzko, which can feel less secure in larger hands.
Our Take: Best for tackling existing mats and the thickest parts of the undercoat. Skip if your dog is already well-maintained or has a very thin single coat.
Oster 18 Tooth Undercoat Rake
While often grouped with Safari, Oster rakes are the “heavy artillery” of the grooming world. The 18-tooth design is wide enough to cover large surface areas on a Husky or Malamute but narrow enough to grab the dead undercoat that slickers miss. I’ve seen this tool remove a grocery bag’s worth of fur in under ten minutes.
The pins are rounded at the tips, making it much safer for the dog’s skin than the Safari dematting tool. It feels professional in the hand—weighty and balanced. For more gear suggestions for large breeds, our pet gear and accessories section has extensive reviews on durable equipment.
The Good
- The rounded ends mean you can use a bit more pressure without worrying about scratching the skin.
- Sturdy construction that doesn’t flex, even when pulled through heavy mats.
- Exceptional at thinning out the “wool” during shedding season.
The Bad
- It is a heavy tool that can cause wrist strain if you are grooming a giant dog.
- Does not “finish” the coat; you will still need a slicker or comb to smooth the guard hairs.
- The price is higher than entry-level Safari tools.
Our Take: Best for large, double-coated breeds during peak shedding season. Skip if you have a smaller dog or a breed with a silky coat.
Chris Christensen Big G Slicker
If the Hertzko is a reliable sedan, the Chris Christensen Big G is a luxury SUV. Groomers on Reddit swear by this brush for its long, “L-shaped” pins that go significantly deeper than the Hertzko. In practice, this means you can brush through a thick coat in fewer passes, which is better for both you and your dog.
The “Big G” has high-density pins specifically designed to fluff and shape the coat while removing debris. It is expensive, but for a dog like a Samoyed or a show-quality Golden, the difference in the finished look is noticeable. For more on high-end maintenance, browse our pet health and care articles for skin health tips.
The Good
- The long pins easily reach the skin on even the densest coats.
- Large head size covers more ground quickly.
- Superior pin durability; they don’t lose their shape or “sink” into the pad over time.
The Bad
- The price is a significant investment for a home groomer.
- The pins are very scratchy; you must use a “tap and pull” technique to avoid skin irritation.
- No self-cleaning button, so you’ll be pulling fur out manually with a comb.
Our Take: Best for owners who want professional-level results and don’t mind the manual cleanup. Skip if you are on a tight budget or have a sensitive dog.
Miller’s Forge Red Nail Clippers
Nail care is often overlooked in double-coated breeds, but thick fur can hide overgrown nails that cause foot pain. Many owners complain that Safari’s basic clippers “crush” the nail, which is painful for the dog. The Miller’s Forge Red (and the Orange handled heavy-duty version) are the gold standard for clean, effortless cuts. These are simple plier-style clippers with incredibly sharp blades.
The Good
- Clean cuts that don’t splinter or crush the nail.
- Simple design with no unnecessary “safety guards” that often just get in the way.
- Lasts for years without needing sharpening.
The Bad
- No safety stop, so you need to be confident in where you are cutting.
- The locking mechanism can sometimes engage on its own while you are working.
Our Take: Best for dogs with thick, tough nails. Skip if you prefer a clipper with a built-in safety guard.
What Real Users Are Saying (Reddit Insights)
General Sentiment
The consensus among community hubs like r/doggrooming and r/greatpyrenees is that Hertzko is the “gateway” brush—great for getting started, but often replaced by professional tools as the dog reaches adulthood and the coat fully develops. Safari is praised for its value, often being the “workhorse” for owners who don’t want to spend $70 on a brush but need something more effective than a grocery store pin brush.
Top Complaints & Warnings
One recurring complaint regarding the Hertzko is the durability of the retraction button. Multiple users on Reddit have noted that if fine hair gets trapped inside, the button can jam.
“The Hertzko is great for about six months, but once my Pyr hit his second blow-out, the button jammed from all the dander and fine fur.” — r/greatpyrenees
Regarding Safari, the main warning involves their nail clippers. Several users report that the Safari Professional Nail Trimmer feels dull compared to Miller’s Forge, leading to a “crushing” sensation rather than a “clipping” one.
“I switched from Safari to Miller’s Forge because my dog would yelp every time I used the Safari ones. They just weren’t sharp enough for his thick nails.” — r/doggrooming
Budget Tips & Value Picks
For those looking for a Chris Christensen experience on a budget, the community often recommends Tougher than Tangles or Yento brushes. These offer longer pins than the Hertzko but at a price point closer to $25. For value in deshedding, the combination of a Safari undercoat rake and a simple Andis steel comb is widely considered the best “bang for your buck” setup.
The Professional’s Secret: Beyond the Big Box Brands
If you want to move beyond basic maintenance, professionals suggest looking at high-velocity dryers. A force dryer (like those from K-9 or Shernbao) can blow the dead undercoat right off the dog after a bath, significantly reducing the amount of raking you need to do. It also helps you spot hidden mats or skin issues like hot spots.
Another secret is using a dematting solution. Products like ‘The Stuff’ or ‘Cowboy Magic’ are silicone-based detanglers that make the hair slippery. When applied to a mat, it allows the brush to glide through without the need for cutting. This is especially helpful for the sensitive skin behind the ears.
How to Properly Line Brush a Double Coated Dog
Simply dragging a brush over your dog’s back isn’t enough. To truly reach the undercoat, you must “line brush.” Start at the bottom of the leg or the base of the tail. Use one hand to pull the fur up, exposing a “line” of skin. Use your slicker brush to brush that small section of hair down. Move up an inch and repeat. This ensures you are hitting every layer of the coat. For a full breakdown of general grooming, see our dog products hub for more specific breed guides.
Best Dog Brushes by Segment
Best for Thick-Coated Giant Breeds
The Oster 18 Tooth Undercoat Rake is the clear winner here. Its ability to plow through the density of a Great Pyrenees or Alaskan Malamute coat without snagging is unmatched in its price range. Pair it with the Chris Christensen Big G for a show-ready finish.
Best for Daily Shedding Control
The Hertzko Self Cleaning Slicker Brush is ideal for breeds with medium-length double coats like Golden Retrievers or Australian Shepherds. The easy cleanup makes it more likely that you will actually use it every day.
Best for Detailing Sensitive Areas
The Safari Dematting Comb excels at cleaning up the small, tight mats that form in high-friction areas like behind the ears and under the armpits. Its sharp blades do the work so you don’t have to pull on the dog’s delicate skin.
Frequently Asked Questions
Is the Hertzko slicker brush effective for very thick coats like a Great Pyrenees?
While the Hertzko is a solid tool, its pins are often too short to reach the skin on a Great Pyrenees. It works well for surface hair and finishing, but for the dense undercoat of a Pyr, you will likely need an Oster or Safari undercoat rake to reach the root of the shedding problem. Many Pyr owners use the Hertzko for daily touch-ups but rely on heavier tools for deep grooming.
Why do some users find that Safari nail clippers crush nails?
Safari nail clippers are budget-friendly, but they can sometimes lose their edge or lack the bypass-cutting power needed for very thick nails. When a blade is dull, it squeezes the nail before cutting, causing discomfort. Professional groomers often recommend Miller’s Forge Red nail clippers instead, as they are renowned for maintaining a sharp edge that slices through thick nails cleanly.
How do you safely remove mats behind a dog’s ears?
The skin behind a dog’s ears is paper-thin and easily folded. To remove mats safely, use a dematting solution like Cowboy Magic to lubricate the hair, then use a Safari Dematting Comb with very short, picking motions. Never pull hard. If the mat is tight against the skin, a professional groomer would recommend using a #10 clipper blade to safely shave it out rather than risking a cut with scissors.
What is the benefit of a self-cleaning slicker brush?
The primary benefit of a self-cleaning slicker brush, like the Hertzko, is time-saving and pin protection. By retracting the pins, the hair is pushed off in one piece. This prevents you from having to manually pick hair out, which can bend the delicate wire pins over time. It also keeps your grooming area much cleaner, as the hair doesn’t fly around during the cleaning process.
Should I use a force dryer for my double-coated dog at home?
Yes, if you have a dog with a heavy undercoat, a high-velocity force dryer is a massive time-saver. It blows water and loose undercoat out of the hair much faster than a standard human hair dryer could. It also helps prevent “wet dog” smell and skin infections by ensuring the dense undercoat is completely dry all the way to the skin. It’s a great supplement to your Safari or Hertzko brushing routine.
Final Verdict: Which Brand Should You Choose?
If you are looking for a user-friendly, clean-up-friendly brush for a dog with a manageable double coat, the Hertzko Self Cleaning Slicker Brush is the way to go. It makes the daily chore of brushing much less of a mess. However, if you are staring down a mountain of undercoat on a Husky, Samoyed, or Great Pyrenees, you need the specialized power of Safari and Oster rakes. These tools are designed to penetrate where slicker brushes fail.
My recommendation for a complete kit: get the Hertzko for daily surface work, the Safari Dematting Comb for the occasional ear tangle, and an Oster rake for the heavy shedding season. This trifecta will cover almost every grooming challenge a double-coated dog can throw at you. Happy grooming!
