How to Remove Mats From Dog Hair at Home (Without Cutting the Coat)

To remove a mat from your dog's hair at home, loosen it with your fingers and a little dog conditioner, then hold the mat firmly and work it apart from its outer edge toward the body, a few strands at a time. Small mats come out this way, sometimes over several short sessions. A mat that sits flat against the skin, covers a large patch, or hurts your dog when you touch it is a job for a groomer or vet, and scissors are the one tool to keep away from it entirely.

The usual way a mat turns into an injury at home is simple: someone finds a knot, grabs the nearest pair of scissors, and cuts. So before any technique, a rule.

Why you shouldn't cut a mat out with scissors

A mat isn't sitting on top of the coat. It grows out of it, and as it tightens it pulls the skin up into itself, so the skin is often much closer to the blade than it looks. The American Kennel Club advises: don't try to cut mats out yourself, because one wrong move from a nervous dog can cause a serious injury. The ASPCA's version has one word in capitals: "NEVER cut mats out with scissors."

If a mat genuinely has to go and it won't comb out, it gets clipped off with electric clippers. VCA Animal Hospitals says the same: clippers only, never scissors.

First, decide what kind of mat you have

Not every knot is the same job. Before you pick up a tool, push a finger into the base of the mat and see what happens.

What you feel	What it is	What to use	At home?
Hair moves apart with light finger pressure	Tangle, not yet a mat	Fingers, then a wide-tooth comb	Yes
A firm knot you can get a comb tooth under; skin moves freely beneath it	Small mat	Dog conditioner + a rotating-pin detangling comb, pins 0.79 in (2 cm) deep	Yes
A dense pad of packed undercoat in a thick or double coat, not tight to the skin	Undercoat mat	9-tooth dematting face, 2.8 in (7 cm) wide, then a comb	Yes, slowly
Flat against the skin, no gap for a comb tooth, or a whole area matted together	Severe matting	Nothing. Groomer or vet	No
Any mat with red, wet, sore or smelly skin underneath	Skin problem under a mat	Vet first	No

Three of those five are home jobs. The two where the mat is tight to the skin, or the skin itself looks wrong, are not.

Before you start

Brush the mat out before any bath, not after. Bathing a matted dog "only makes their hair tighter and harder to brush out," according to the AKC, and VCA warns tangles can become impossible to remove after a bath. If your dog is due a bath, the mats come out first.

Set up somewhere your dog can lie down. Mats sit where the coat moves most (behind the ears, the armpits, the groin, under the collar), and those are exactly the spots a dog tenses up about. We explain why mats keep forming in the same places in a separate piece. For this job it's enough to know you'll be working on awkward, sensitive spots, and a relaxed dog makes it far easier.

Have treats and a time limit. The AKC's advice is to keep at a stubborn mat for a few minutes, a couple of times a day, over several days rather than finishing it in one go. A mat that doesn't come out today can be finished tomorrow.

Step by step: working a mat out

1. Loosen it by hand. Work a little dog conditioner into the mat with your fingertips. The AKC lists fingers, dog conditioner and a couple of different combs as the best way to remove a mat. Use a conditioner made for dogs, not your own; the AKC also advises against using human shampoo and conditioner on a dog. Then pull the edges of the mat apart with your fingers, teasing loose the hair around its outer rim.

2. Hold the mat. Grip the mat between your fingers, close to the skin, with your free hand. Every tug you make now lands on your hand instead of your dog's skin.

3. Comb from the outside in. Start at the outer edge of the mat and work toward the body, as the AKC describes, taking short strokes that pick off a few strands at a time. Our 2-in-1 Undercoat Rake & Rotating Detangling Comb is built for this stage on its comb side: the pins rotate as they meet resistance, so they turn with a knot instead of dragging it, and they reach 0.79 in (2 cm) deep across a 3.9 in (10 cm) head. Keep to the comb side for mats. The rake face on the back is for loose undercoat, not knots.

4. For a pad of packed undercoat, split it first. On thick double coats — a Golden, a Shepherd, a Husky mid-shed — a mat is often a flat felt of dead undercoat rather than a twisted knot. Our Double-Sided Undercoat Rake has a 9-tooth side meant for working through that kind of pad, with stainless teeth across a 2.8 in (7 cm) head. Pull it with the direction of the hair, in short strokes, while you still hold the mat. Don't use it on mats that are tight to the skin, and skip it on curly or doodle coats, where the problem is a twisted knot rather than packed undercoat. If your dog only ever gets the odd small knot, you don't need this tool at all; a comb and your fingers are enough.

5. Check you actually reached the skin. When the mat looks gone, run a fine-tooth comb through the same spot from root to tip. The straight comb in our 2-in-1 Pet Grooming Comb Set has a wide-tooth section and a fine-tooth section on a 7.5 in (19 cm) spine. If the fine teeth stop partway down, there's still a knot at the base, and it will build back into a mat.

6. Look at the skin. Once the hair is out, part the coat and look. The ASPCA notes that even very mild mats can irritate the skin and progress to infected sores, and that fleas and ticks can hide deep inside a mat. Anything more than a little pinkness from brushing goes to the vet.

When to stop and book a groomer

Stop if:

• You can't get a comb tooth between the mat and the skin.
• Your dog flinches, growls or pulls away every time you touch the spot.
• The matting covers a whole area (the rear, the belly, the back) rather than a few separate knots.
• You've spent several short sessions on one mat and it isn't getting smaller.

The ASPCA's guidance is simple: a mat that can't be easily brushed out should go to a groomer or veterinarian, and a severely matted dog may need sedation and a full-body clip. That isn't a failure. It's the kind option.

Keeping them from coming back

The mats you'll remove most often are the ones that formed at the base of the coat while the top looked brushed. The AKC's instruction for brushing is to work all the way down to the skin with gentle strokes, and it names behind the ears and under the legs as the places mats most commonly develop.

For those tight spots (armpits, behind the ears, the groin), see our guide to brushing the trouble zones. If you live with a cat too, cat mats need a gentler hand and a different set of rules, covered in how to get mats out of cat fur.

If your dog has a short, smooth coat — a Lab, a Beagle, a Boxer — you almost certainly don't need any of the tools above. Short coats rarely hold a mat; a rubber mitt or a bristle brush handles their loose hair.

Frequently Asked Questions

Q: Can I use conditioner to get mats out of my dog's hair?

A: Yes, a dog conditioner worked in with your fingers helps the comb slide, and the AKC lists it among the best ways to remove a mat. Use one made for dogs rather than your own. It loosens a mat; it doesn't dissolve one, so you still have to comb it out.

Q: Does removing a mat hurt my dog?

A: It shouldn't if you hold the mat so the pull lands on your hand, not the skin. If your dog is in pain even when you do that, the mat is too tight for home removal or the skin under it is sore, and it's time for a groomer or vet.

Q: How long does it take to remove a mat?

A: A small mat can come out in a few minutes. A dense one may take several days of short sessions, a few minutes a couple of times a day, which is the pace the AKC suggests. If it isn't shrinking after that, stop and book a groomer.

Q: Should I just shave my matted dog?

A: For a severely matted coat, a full clip by a groomer or vet is often the most comfortable option for the dog. Don't attempt it with scissors at home. And don't shave a healthy double coat just to prevent mats in the future; regular brushing down to the skin does that job.
