An undercoat rake is a grooming tool built specifically to reach past a dog’s visible topcoat and remove loose, dead hair from the dense undercoat underneath, without cutting the outer guard hairs or damaging healthy fur. It typically features one or two rows of slightly angled, rounded-tip metal pins or blades set into a handle, spaced to slide through thick fur while catching and pulling out the loosened undercoat.
Undercoat rakes are considered essential equipment for double-coated breeds, which grow both a soft, insulating undercoat and a coarser topcoat. Without regular raking, the undercoat can build up, trap moisture and debris against the skin, and contribute to matting, skin irritation, and a significantly heavier shedding load around the house during seasonal coat blow.
How an Undercoat Rake Differs From Other Grooming Tools
A slicker brush, with its many fine wire bristles, is designed to smooth the topcoat, work through minor tangles, and remove loose surface hair, but it generally doesn’t reach deep enough into a thick double coat to significantly reduce undercoat volume. A pin brush is similarly better suited to surface detangling and finishing than deep undercoat removal.
An undercoat rake, by contrast, is built with longer, sturdier teeth specifically angled and spaced to penetrate through the topcoat and catch the dense, often matted layer of dead undercoat hair closer to the skin. This makes it the more effective tool during heavy seasonal shedding periods, when a dog’s undercoat can release a dramatic amount of loose hair in a relatively short window.
A separate but related tool, the deshedding tool or blade-style deshedder, uses a slightly different mechanism, employing a fine-toothed metal edge to lift and remove loose undercoat hair in a single stroke. Many groomers use rakes and deshedding tools together, starting with a rake to loosen and remove bulk undercoat before finishing with a deshedding tool or slicker brush for a smoother final result.
Rakes also come in different tooth spacings and lengths designed for different coat densities. A rake with widely spaced, longer teeth generally suits thick, heavy coats like those on Huskies or Malamutes, while a finer, more closely spaced rake works better on moderately coated breeds, so matching the tool to the coat type makes a noticeable difference in comfort and effectiveness.
Why Regular Undercoat Raking Matters
For double-coated breeds like Golden Retrievers, Siberian Huskies, German Shepherds, and Corgis, the undercoat naturally sheds in significant volume during seasonal transitions, commonly called “blowing coat.” If this loose undercoat isn’t regularly removed, it tends to mat against the skin, trap heat and moisture, and create an environment where skin irritation, hot spots, and even fungal or bacterial issues can develop more easily.
A trapped, matted undercoat can also interfere with a dog’s natural ability to regulate body temperature, since a healthy double coat is actually designed to insulate against both heat and cold when properly maintained. A dense, matted layer disrupts this natural insulation, which is part of why owners are sometimes surprised to learn that shaving a double-coated breed down to solve a matting problem can backfire and make temperature regulation harder rather than easier.
Beyond the health benefits, consistent undercoat raking meaningfully reduces the amount of loose hair shed around the home, since much of what ends up on floors and furniture is dead undercoat that would otherwise fall out naturally over a period of weeks rather than being removed in a single grooming session. For owners of heavy-shedding breeds, a regular raking routine during shedding season can make an enormous practical difference.
Raking also gives owners a chance to check the skin underneath the coat for early signs of irritation, parasites, lumps, or matting that might otherwise go unnoticed under a thick layer of fur, making it a useful health-monitoring habit in addition to a grooming task.
For dogs with allergies or sensitive skin, keeping the undercoat properly thinned out can also make topical flea and tick treatments more effective, since a dense, matted undercoat can prevent a topical product from reaching the skin as intended. This is a practical secondary benefit that goes beyond simple hair volume management.
How to Use an Undercoat Rake Safely
Before raking, it helps to make sure the coat is dry and free of major mats or tangles, since forcing a rake through a large mat can pull uncomfortably on the skin. Working in the direction of hair growth, in short, gentle strokes, and checking in on the dog’s comfort level throughout the session helps keep the experience positive rather than something the dog starts to dread.
Because the teeth on an undercoat rake are sturdier and go deeper than a standard brush, it’s important not to press too hard or rake too aggressively over one spot repeatedly, particularly over bony areas like the hips or spine, where skin is more sensitive and prone to irritation from excessive pressure. Short, frequent sessions spread across several days tend to work better than one long, forceful session, especially for a dog with a heavily matted or overdue coat.
Pairing raking sessions with a calm environment, such as after a walk when the dog is naturally more relaxed and settled, tends to make the experience go more smoothly than attempting it when a dog is wound up or overly energetic, since a squirming dog is both harder to groom safely and more likely to associate the tool with an unpleasant experience.
Starting slowly with short sessions when introducing a new tool, paired with treats and praise, helps dogs who are initially uncertain about the sensation adjust to regular raking as a normal, even enjoyable, part of their routine rather than something stressful.
Cleaning the rake itself between sessions, removing trapped hair from between the teeth, keeps it working effectively and prevents old debris from being reintroduced to a freshly groomed coat. A quick wipe-down after each use extends the tool’s lifespan and keeps grooming sessions more hygienic overall.
Common Misconceptions and Tips
A common misconception is that an undercoat rake is only necessary during obvious shedding season. In reality, most double-coated breeds benefit from regular, if less frequent, undercoat maintenance year-round, since a small amount of undercoat shedding happens continuously even outside of the major seasonal blowouts.
Another misconception is that using an undercoat rake will remove or damage the topcoat, leaving a dog’s coat looking thin or patchy. When used correctly and gently, a rake is designed to target the loose undercoat specifically and should not pull out healthy, still-rooted topcoat hair in the process.
Some owners also assume any brush marketed as a “deshedding tool” will work the same way as a proper rake. Tools vary significantly in design, tooth length, and spacing, so choosing one genuinely suited to your dog’s specific coat type and thickness, rather than a generic option, produces meaningfully better results with less discomfort for the dog.
If a dog’s coat is already significantly matted, it’s generally better to consult a professional groomer before attempting extensive raking at home, since a heavily matted coat may need to be carefully worked out in stages, or in severe cases trimmed down, rather than pulled through with a rake in a single session.

Frequently Asked Questions
Can I use an undercoat rake on a single-coated dog?
It’s generally not necessary and can be uncomfortable, since single-coated breeds don’t have the dense undercoat layer a rake is designed to remove. A slicker brush or grooming glove is usually a better fit for these coat types.
How often should I use an undercoat rake?
During heavy seasonal shedding, several times a week is often helpful, while a lighter, less frequent routine works for maintenance the rest of the year. The right frequency depends on your dog’s specific breed and coat thickness.
Does raking hurt a dog’s skin?
Used gently and correctly, raking should not hurt, though pressing too hard or working over the same spot repeatedly can cause irritation, especially over bony areas. Short, gentle sessions are the safer approach.
What’s the difference between an undercoat rake and a deshedding tool?
A rake uses angled pins to catch and pull loose undercoat, while a deshedding tool typically uses a fine metal edge to lift hair away in a single stroke. Many groomers use both together for the best results.
Will an undercoat rake stop my dog from shedding completely?
No tool eliminates shedding entirely, since it’s a normal biological process. Regular raking significantly reduces the amount of loose hair that ends up around your home rather than stopping shedding altogether.
