You run your hand down your dog’s side and feel it: a hard, felted clump behind the ear or under a leg. Mats are more than a cosmetic problem. They pull on the skin every time your dog moves, trap moisture and dirt, and can hide redness or sores underneath. The good news is that small mats can usually be worked out at home with the right tools and a lot of patience. This guide walks you through why mats form, what to use, a gentle step-by-step method, and when it’s kinder (and safer) to let a professional handle it.

Why Dog Hair Gets Matted

Mats form when loose hair gets caught in the coat instead of falling out, then twists around the hair still growing. Over time friction, moisture and dirt press that bundle into a tight, felt-like knot. Dogs with long, curly, silky or double coats — think Poodles and doodle mixes, Shih Tzus, Yorkies, Collies, Golden Retrievers and Bernese Mountain Dogs — are the most prone.

The usual hot spots are areas that rub or stay damp: behind the ears, under the collar or harness, the “armpits,” between the back legs, the belly, the tail and the feathering on the legs. Seasonal shedding, swimming, baths without a thorough dry, and wearing sweaters or harnesses all make mats more likely.

Mat or Tangle? Check Before You Start

A tangle is loose and you can still see individual hairs; a comb will usually work through it. A mat is denser and feels like a clump of felt. A pelted coat is the most serious stage: large sections are matted tight to the skin, almost like a blanket. Gently part the hair around the clump. If you can slide a comb between the mat and the skin, you can likely work it out at home. If the mat sits flat against the skin, or covers a large area, skip ahead to the “when to call a groomer or vet” section below.

The Tools That Make It Easier

You don’t need a professional grooming kit, but the right tools make dematting faster and much more comfortable for your dog:

• A detangling spray or conditioner adds slip so hair slides apart instead of breaking.
• A dematting comb or mat splitter has blades designed to cut through the middle of a mat in small sections.
• A slicker brush loosens the outer hair once a mat starts to break up.
• A metal “greyhound” comb with wide and narrow teeth lets you check you’ve reached the skin.
• High-value treats to keep the session positive.

Step-by-Step: How to Remove a Mat at Home

1. Choose a calm moment. After a walk, when your dog is relaxed, works best. Keep sessions short — 5 to 10 minutes.
2. Work on a dry coat. Water tightens most mats, so never bathe a matted dog before dematting.
3. Spray the mat with detangler and gently massage it in with your fingers. Wait a minute or two.
4. Hold the hair at the base, between the mat and the skin. This is the most important step: your fingers take the pulling, so your dog’s skin doesn’t.
5. Loosen with your fingers first. Tease the outer edges of the mat apart, pulling small strands away from the clump.
6. Split large mats. Slide a dematting comb or mat splitter into the mat and work outward, in the direction the hair grows, to break it into smaller pieces.
7. Brush from the outside in. Use a slicker brush on the tips of the hair first, then work closer to the skin in short, light strokes.
8. Finish with a comb. When the comb glides all the way to the skin without catching, you’re done.
9. Reward and take breaks. Give a treat every minute or so. If your dog gets restless, stop and finish another day.

A Word of Caution About Scissors

It’s tempting to just snip the mat off, but cutting with regular scissors is one of the most common ways owners accidentally injure their dogs. Matted hair pulls the skin up into the clump, so the skin can be much closer to the blades than it looks. If a mat truly needs to come out, a pair of electric clippers held flat against the body is usually safer than scissors — and a professional groomer is safer still. If you do use scissors, only cut through the mat lengthwise (away from the skin) to split it, never across the base.

How to Prevent Mats From Coming Back

• Brush regularly. Long or curly coats often need brushing several times a week; short coats need much less. Use the “line brushing” method: part the hair in sections and brush each layer down to the skin.
• Focus on friction zones — behind the ears, collar area, armpits and back legs.
• Dry completely after baths and swims. Damp hair mats quickly. Our guide on how to bathe your dog at home covers drying tips.
• Brush before every bath, since washing tightens existing tangles.
• Remove harnesses and sweaters when your dog is relaxing at home.
• Book regular trims for breeds whose hair keeps growing, such as Poodles and doodles.

When to Call a Groomer or Vet

Home dematting is for small, loose mats. Get professional help if:

• The mat is tight against the skin, or large areas of the coat are pelted.
• Your dog cries, snaps or is very stressed when you touch the area.
• You notice redness, sores, a bad smell, discharge, swelling, or anything moving under the mat.
• Mats are near sensitive areas like the eyes, ears, genitals or rear end.

A groomer can safely shave out severe mats — often the most humane option, since the hair grows back. If the skin underneath looks irritated or infected, or your dog is in pain, see your vet before (or instead of) grooming. Sudden heavy matting in an older dog can also be a sign they’re having trouble grooming themselves, which is worth mentioning at their next checkup.

Final Thoughts

Mats are easiest to fix when they’re small, so a few minutes of brushing each week is the best prevention there is. When you do find one, go slowly: detangler first, hold the hair at the base, split it into pieces, and finish with a comb. Keep sessions short and full of treats, and don’t hesitate to call a groomer for anything tight to the skin. Your dog will be more comfortable — and grooming will become something you both look forward to.
