How to Remove Matted Dog Hair Safely (Without a Shave)

Most matted coats start the same way – three skipped brush sessions, one wet swim at the dog park, and a humid week in Sydney. By the time you notice the lump behind the ear, the knot is already pulling at the skin. The good news is that most mats come out at home with the right tools and the right order of work.

Mild to moderate mats come out with a slicker brush, a metal dematting comb and a dog-safe detangler – never scissors, never a wet bath first. Severe mats that sit tight to the skin belong with a groomer or vet, especially on double-coated breeds. Brush before the bath, brush the coat dry, and check the trouble spots weekly.

Why mats form in the first place

Mats are tight knots of loose fur, dead undercoat, dirt and sweat that bind together when the coat isn’t brushed through to the skin. They show up first in the high-friction zones – behind the ears, under the collar, in the armpits and at the chest. Long-coated and curly breeds like cavoodles, maltese shih tzus and poodles hold loose hair inside the topcoat instead of shedding it onto the lounge, so the undercoat tangles in place.

Humidity and water make it worse. A swim followed by an undried coat is a classic trigger, and so is summer in QLD and northern NSW – warm humid air keeps the coat damp for hours between brushes. Most owners don’t realise their dog has a mat until they feel a lump that doesn’t move with the skin underneath.

The tools that actually work

You don’t need a kit the size of a salon. For most home jobs we use four things:

A slicker brush with fine, slightly bent pins – Wahl and Andis both sell decent ones at Petbarn and Pet Circle.

A long metal dematting comb, sometimes called a ‘greyhound comb’, with widely spaced teeth on one side and fine teeth on the other.

A dog-safe detangling spray – Aristopet, PAW by Blackmores and Rufus & Coco all make AU-stocked options.

A handful of high-value treats, because dematting is uncomfortable and the dog will remember.

Skip the scissors. The comb needs to be metal – plastic snaps on a dense coat. If you only buy one thing, buy the comb; the slicker is the finishing tool, not the dematting tool.

How to fix it at home, step by step

Work in a quiet room, with the dog standing or lying on a non-slip surface. Brush dry coats only – wet mats tighten like felt and become almost impossible to tease apart.

Locate every mat

Run your fingers through the coat against the lay of the hair. Decide if each lump moves freely (mild), sits flat to the skin (moderate), or won’t let you slide a comb under it (severe). Severe means stop and book a groomer.

Spray a detangler

Lightly spritz the mat from base to tip and let it sit for two or three minutes. Don’t soak the coat – damp is fine, wet is not.

Hold the base of the mat

Pinch the hair between the mat and the skin with your free hand. This is the bit most owners skip, and the bit that turns the dog against grooming forever.

Tease from the outside in

Use the wide-toothed end of the comb and pick at the outer edge of the mat in short strokes. Don’t drag through the middle – you’ll only tighten the knot.

Switch to the slicker once the mat starts to break up

Light, flicking strokes against the lay of the hair, then with it. Heavy pressure leaves brush burn on the skin.

Comb through with the fine teeth

A final pass confirms the knot has broken up. If the comb still catches, the mat isn’t fully out – go back to step four.

Treat, pause and check the next spot

Most dogs tolerate four to six minutes of dematting before they need a break. The dogs who hate grooming are usually the ones who got pushed past 10 minutes on day one.

Time per mat varies. A small ear-tag mat on a maltese shih tzu takes us 5 to 10 minutes; a wider chest mat on a long-coated breed can take 20 minutes or more, split across two sessions.

Common mistakes that make mats worse

Bathing the dog first – wet hair tightens the knot, every time.

Cutting at the mat with scissors. The skin tents up into the base of the mat and ends up closer to the blade than it looks.

Brushing only the top of the coat. Mats sit at the skin, not at the tips.

Using human conditioner. Dog skin sits at a different pH and human products dry it out.

Letting the dryer run too long on one spot. Heat builds up on a small dog faster than owners expect.

When it becomes a vet issue

Some mats hide a problem. Stop the home dematting and book a vet visit if you see or smell any of these:

Broken or weeping skin under the mat – red, yellow or warm to touch.

A foul smell from the matted area, especially near the ears or backside.

The dog flinching, snapping or yelping when you go near the spot.

Visible parasites under the mat – fleas, ticks or maggots in the warmer months.

A pelted coat that lifts off the skin like a jumper, especially on a small dog.

Hot spots sit underneath mats more often than owners expect, especially through humid weeks. And don’t shave a double-coated dog to fix this – on huskies, golden retrievers and australian shepherds, shaving damages the regrowth and can leave permanent patches. A vet or accredited PIAA groomer will slide clippers under the mat against the skin, not over the top of the coat.

Australian context – heat, humidity and the wrong fix

Summer in Brisbane hits 32°C by 9am most days from December onward, and the instinct is to shave the dog cooler. It backfires. The double coat insulates against heat as well as cold, and shaving exposes the skin to sunburn. The AVA treats regular coat care as part of basic companion-animal welfare for long-coated and double-coated breeds.

Mobile groomers across metro AU run dematting visits in the $80 to $150 range in 2026. A salon dematting plus full groom on a cavoodle or spoodle typically runs $110 to $180; pelted coats often cost more, and in a small number of cases the vet needs to sedate the dog to get the clippers safely under the coat.

How to prevent the next mat

Prevention is the part that actually saves the coat. Brush a long or curly coat through to the skin every two to three days; long-coated breeds like briards and double-coated dogs need a weekly undercoat rake plus a full brush-out during the spring ‘blow coat’. Dry thoroughly after every bath, swim or wet-grass walk.

Brush before the bath, always. Wet matted hair tightens; clean dry hair untangles. The AKC recommends checking for mats every time you brush, and that habit alone catches most of them at the loose-knot stage. Replace the slicker every 18 months – the pins blunt with use and start dragging instead of gliding through.
