Safe Dematting Procedures for Double Coats

By Lisa Morgan, CMG|Updated February 2026|9 min read

Mats happen. Even with diligent brushing and proper maintenance, life occasionally interferes with grooming schedules. A week of illness, an unexpected trip, or simply missing a critical spot during routine care can result in matting that requires correction. The question is not whether you will ever face a mat, but how you will handle it when you do.

In my eighteen years of grooming, I have seen matting range from minor tangles requiring five minutes of work to complete pelting where the only humane option was shaving. The severity of the outcome depends largely on how quickly the problem is addressed and how carefully it is handled. Early intervention with proper technique preserves the coat. Delayed or improper handling turns manageable tangles into coat-destroying disasters.

Understanding How Mats Form

Mats are not random. They form in predictable ways and predictable locations based on coat structure and behavior. Understanding the formation process helps both prevent mats and remove them effectively.

The Anatomy of a Mat

A mat begins when loose undercoat hairs tangle with each other and with guard hairs. This initial tangle is loose and easy to work out if caught immediately. Left unaddressed, the tangle collects more loose fur, compresses from movement and friction, and begins to felt together.

As the mat tightens, it pulls at the skin where the hairs are rooted. This causes discomfort and, in severe cases, restricts blood flow to the skin beneath the mat. Severely matted areas can develop skin lesions, infections, and permanent hair follicle damage.

The progression from tangle to mat to pelt can happen faster than many owners expect. A small tangle behind the ear can become a tight mat within a week of neglect, particularly during shedding season when loose undercoat is abundant.

Common Mat Locations

Behind the ears is perhaps the most frequent mat location. The fur here is finer, tangles more easily, and receives constant friction from head movement and scratching.

The armpit regions mat quickly due to constant movement of the front legs. The fur there grows in multiple directions, creating natural tangle points.

The collar line develops mats from friction if your dog wears a collar constantly. Consider removing collars when at home or using harnesses for daily wear.

The britches and feathers, with their longer fur, catch debris and tangle during movement. Dogs who spend time outdoors in vegetation are particularly prone to matting in these areas.

The ruff around the neck mats during shedding season as loose undercoat becomes trapped in the dense fur.

When to Stop: If a mat is tight against the skin, pulling on live hair, or the dog shows signs of significant pain during removal attempts, stop. Forcing removal of severe mats causes trauma to the skin and coat. At this point, professional evaluation is needed to determine whether the mat can be safely removed or requires shaving.

Assessment Before Dematting

Before attempting mat removal, assess the situation honestly. Not every mat can or should be brushed out. Knowing the difference prevents unnecessary suffering and coat damage.

Evaluating Mat Severity

A loose tangle feels soft when you gently squeeze it. You can feel air space within the mass, and you can see some separation between the hairs. These tangles are good candidates for brushing out.

A moderate mat feels denser but still has some give. When you gently pull at the edges, you can separate small amounts of fur from the main mass. These can usually be worked out with patience and proper technique.

A severe mat feels solid, almost like felt. There is no air space, no give, and you cannot separate any fur from the edges without significant pulling. The mat may be adhered directly to the skin.

A pelt is when matting has spread across large sections of the body, with mats connecting to each other. The fur has essentially become a shell over the dog's body.

Decision Guidelines

Loose tangles and moderate mats can typically be worked out at home with the techniques described below. Plan for the work to take time, and be prepared to stop if the dog becomes stressed.

Severe individual mats benefit from professional attention. A groomer can evaluate whether the mat can be safely removed or whether spot shaving is the humane choice.

Pelting requires professional grooming. Do not attempt to brush out a pelted coat at home. The only ethical option is typically a full shave, which should be done by a professional who can monitor skin condition and address any wounds beneath the matting.

Dematting Tools and Products

The right tools make dematting safer and more effective. Using inappropriate tools increases the risk of skin injury and coat damage.

Dematting Combs

A dematting comb has blades rather than teeth that cut through the mat, splitting it into smaller, more manageable sections. Quality dematting combs have curved blades with protected edges that minimize the risk of skin cuts.

Use the dematting comb in short strokes, working from the outer edge of the mat toward the skin. Never force the tool through; if it catches, reposition and try a different angle.

Mat Splitters

Mat splitters are similar to dematting combs but typically have fewer, larger blades. They excel at splitting large mats into smaller sections that can then be worked out with a comb or brush.

Hold the mat with one hand to provide counter-pressure, then work the splitter through the mat in an outward direction (away from the skin). The goal is to divide the mat, not to cut it completely out.

Detangling Sprays

Detangling spray or conditioning spray applied to the mat can help loosen the fibers. Spray liberally, work the product into the mat with your fingers, and allow it to sit for several minutes before attempting removal.

Note that detangling spray helps with tangles and moderate mats. It will not magically dissolve severe matting. If the spray does not seem to be helping, the mat may be too severe for home removal.

Tool Maintenance: Keep dematting tools clean and sharp. Dull blades pull rather than cut, increasing discomfort. Wipe blades after each use and oil the pivot points periodically. Replace tools when the blades become noticeably dull.

Step-by-Step Dematting Technique

Follow this systematic approach for safe mat removal. Patience is essential; rushing causes pain, skin damage, and coat loss.

Step 1: Isolate the Mat

Using your fingers, determine the exact boundaries of the mat. Where does it start and stop? How close is it to the skin? Knowing these dimensions prevents working on healthy coat unnecessarily.

Step 2: Apply Detangler

Spray detangling solution onto the mat until it is thoroughly saturated. Work the product into the mat with your fingers. Wait three to five minutes for the solution to begin loosening the fibers.

Step 3: Hold the Base

Place your fingers between the mat and the skin, gripping the hair at the base near the skin. This hold provides counter-pressure so that when you work on the mat, you are not pulling on the skin. Maintaining this hold throughout the process is crucial for preventing pain.

Step 4: Split the Mat

Using your dematting comb or mat splitter, work from the outer edge of the mat toward the base. Your goal is to split the mat into smaller sections. Take small strokes, removing only a few fibers at a time.

If the tool catches and cannot move, do not force it. Reposition, try a different angle, or switch to a tool with smaller blades.

Step 5: Work Out Small Sections

Once the mat is split into smaller pieces, switch to your slicker brush or greyhound comb to work out each section. Start at the tips of the hair and work toward the base, gradually working deeper into each section.

Step 6: Brush Surrounding Area

After the mat is removed, brush the surrounding area thoroughly with your regular tools. This removes any remaining loose hair and ensures no secondary tangles have formed during the dematting process.

Special Situations

Certain dematting scenarios require modified approaches or additional caution.

Mats Near the Skin

When a mat sits directly against the skin with no space for fingers between, do not attempt removal with cutting tools. The risk of skin laceration is too high. These mats typically require professional shave-out with clippers designed for close work.

Mats on Sensitive Areas

Behind the ears, in the groin area, and around the face require extra gentleness. The skin is thinner, and the dog is more sensitive to discomfort. Work more slowly and be prepared to take breaks.

Post-Swim Tangles

Wet fur that dries tangled is particularly difficult to demat. If possible, brush through the coat while still damp after swimming. Once water-set tangles dry completely, they become harder to work out than friction mats.

Multiple Mats

When facing numerous mats, address them across multiple sessions rather than one marathon effort. Prolonged dematting is stressful for the dog, and your own fatigue increases the risk of mistakes.

Prevention Strategies

The best dematting strategy is preventing mats from forming in the first place.

Regular brushing catches tangles before they become mats. Following a consistent grooming schedule is far less work than addressing matting after it develops.

Daily checks of problem areas take thirty seconds and catch developing issues immediately. Make checking behind ears, armpits, and collar line part of your daily routine.

Keeping the coat clean reduces mat formation. Dirt and debris act as nucleation points around which tangles form. Regular bathing with proper drying prevents this buildup.

During shedding season, increased grooming frequency is essential. The loose undercoat that causes most matting is at its peak during coat blow.
