How to Brush a Dog With Long Hair? | Mat-Free Coat Routine

A long, beautiful coat looks great until mats sneak in behind the ears or under the legs. The right brushing technique removes loose fur, distributes natural oils, and keeps your dog comfortable. Here is the exact method that works for every long-haired breed, along with the tools that make it easier.

What Tools Do You Need to Brush a Long-Haired Dog?

Using the wrong brush causes snags and frustration. Long coats need specific tools for different layers and areas.

• Slicker brush: Your daily workhorse for removing undercoat and preventing mats across the main body.
• Pin brush: Ideal for long hair; its long, round-ended pins glide through without scratching the skin.
• Metal comb: Essential for sensitive spots like ears, paws, and for checking that no small mats remain after brushing.
• Undercoat rake: Use once weekly (or more during shedding season) to pull deep undercoat from double-coated breeds.
• Dematting tool or rake: For stubborn mats only — use short strokes with medium pressure, never yanking.
• Detangler or conditioner spray: Mist onto individual layers to help the brush slide through and prevent breakage.

Deciding between these options is easier when you compare features side by side. Our tested roundup of the best dog brushes for long hair breaks down which tool suits each coat type and budget.

The Step-by-Step Brushing Protocol for Long Hair

Brushing in the wrong order can push tangles deeper. Follow this sequence for a thorough, gentle session that your dog tolerates well.

1. Prepare the dog. Remove the collar. Run your fingers through the coat first to find tangles and let the dog settle.
2. Position for access. Start with the dog lying on its back to reach the underside, then flip to its belly for the sides and back.
3. Section the hair. Use hair ties or clips to separate the coat into manageable sections, especially on legs and the tail.
4. Lift and brush from the base. Lift a section of hair with one hand to expose the skin. Brush with your other hand from the root to the tip — base to end — using light to moderate pressure. Firm but not hard strokes remove knots without scratching.
5. Follow the area sequence. Start at the bottom of the back feet and work upward: back feet → up legs → tail → back → sides → chest → front legs → ears. Pay close attention between toes, under-arms, the belly, the sides of the face, and the base of the tail.
6. Handle tangles gently. For knots, use your fingers or a comb to work them out — never pull. Apply detangler spray if needed. If a mat is very tight against the skin, clip it out rather than pulling; scissors near the skin can cause serious injury because the skin is often trapped inside the mat.
7. Finish with the metal comb. Comb through small sections everywhere to confirm no mats remain.

How Often Should You Brush a Long-Haired Dog?

Frequency depends entirely on coat type, and getting this wrong is the main cause of matting.

• Silky or curly coats (Shih Tzu, Yorkie, Poodle mixes): Brush daily. These coats mat quickly and a single missed day can create tangles that take 20 minutes to undo.
• Double-coated long-haired breeds (Collie, Sheltie, Golden Retriever): Brush 2–3 times weekly. Use an undercoat rake during heavy shedding seasons (spring and fall) to pull loose undercoat before it traps against the topcoat.
• Session length: Most long-haired dogs need 10–15 minutes per session. Spread this across two shorter sessions if the dog gets restless.
• Bathing before brushing: Always brush thoroughly before a bath to remove loose hair and tangles. Wet brushing without conditioner causes breakage and split ends — if you must brush wet hair, use a high-quality conditioner spray first.

Common Mistakes That Hurt the Coat or the Dog

Even owners with good intentions make these errors regularly. Avoiding them protects both the coat and your relationship with the dog.

• Scissors on mats: The most dangerous mistake. The skin is often pulled up inside a mat, and scissors can cut deep. Use clippers or a dematting tool instead.
• Pulling on the skin: When you hit a mat, hold the fur close to the skin with your free hand to anchor it before brushing. This prevents the brush from stretching and tearing the skin.
• Rushing sensitive areas: The belly, private parts, anus, and base of the tail are highly sensitive. Go extra slowly and use the metal comb rather than a brush in tight spots.
• Ignoring stress signals: If the dog shows discomfort — flattened ears, whale eye, lip licking, or trying to move away — stop immediately. Try again later with shorter sessions and more treats.
