Finding a mat in your dog’s coat can feel like discovering a tiny, tangled monster. It’s easy to panic and grab the nearest scissors, but that often makes things worse. Mats are not just unsightly; they pull on your dog’s skin, restrict movement, and trap moisture, dirt, and bacteria. The good news is that with the right tools and a calm approach, you can safely free your dog from those painful knots. This guide will walk you through exactly how to handle mats from start to finish, so both you and your pup stay comfortable.

Why Mats Form and Why They Matter

Mats happen when loose, shed hair gets trapped against the healthy coat, tangling into a dense clump. This is especially common in double-coated breeds like Bernese Mountain Dogs, which have a thick undercoat that sheds heavily. If you have one of these breeds, you might already be wondering, Do Bernese Mountain Dogs Shed A Lot? What to Know (spoiler: yes, they do). That constant shedding, combined with friction from collars, harnesses, or just rolling on the carpet, creates prime matting conditions. Mats aren’t just a cosmetic issue. They can pinch the skin, restrict blood flow, and hide hot spots or parasites. In severe cases, a tight mat can even cause a hematoma (a blood blister) if it pulls the skin away from the body. That’s why it’s so important to address mats early and gently.

Step 1: Assess the Matting Severity

Before you touch a single tool, run your fingers through your dog’s coat. Can you easily separate the hairs with your fingers? If yes, those are light tangles you can brush out. If the mat feels tight, solid, and you can’t get your fingers through it, it’s a moderate to severe mat. A good test: if you can pinch the mat and lift it away from the skin, you have room to work. If the mat is flat against the skin and you can’t see the skin underneath, it’s likely a “pelted” mat. In that case, do not try to brush it out. Brushing a pelted mat will only pull the skin and cause intense pain. For pelted mats, the safest and most humane option is to clip them off with clippers (or visit a professional groomer). Never use scissors near the skin, as it’s very easy to accidentally cut your dog.

Step 2: Gather the Right Tools

Using the wrong brush on a mat is like trying to untangle a necklace chain with a fork. You need specific tools. Start with a slicker brush (a flat, rectangular brush with fine, bent wires) and a wide-toothed metal comb. For stubborn mats, a dematting tool or a mat splitter (which has a small, sharp blade inside a protective guard) can help. You’ll also need a good detangling spray or conditioner to lubricate the hair. Avoid using human conditioners, as they can be too heavy for dog fur. If you have a double-coated breed like a Bernese Mountain Dog, keep in mind that their exercise needs can affect coat condition.

Step 3: The Dematting Process (Step by Step)

Work in a quiet, well-lit space. Give your dog a chance to sniff the tools and give them a treat. Then follow these steps:

  • Spray the mat: Liberally apply a detangling spray to the mat and the surrounding hair. Let it sit for 30 seconds to soften the hair.
  • Hold the mat at the base: Use your non-brush hand to hold the mat firmly against your dog’s skin. This prevents the brush from pulling the skin.
  • Start at the edges: Using the slicker brush, work from the outer edges of the mat inward. Use short, gentle strokes. Never yank or saw at the mat.
  • Use the comb to separate: Once the outer edges loosen, use the wide-toothed comb to gently tease apart the hair. If you hit a snag, go back to the slicker brush.
  • For stubborn mats: Use the dematting tool or mat splitter. Insert the blade into the mat (parallel to the skin, never pointing down) and gently slice through the mat in a sawing motion. This cuts the mat into smaller sections that are easier to brush out.
  • Reward frequently: Give a treat and praise after every successful section. If your dog shows signs of stress (whining, lip licking, trying to move away), stop and take a break. Forcing the process can create a negative association with grooming.
Pro Tip

If you have a multi-pet household, consider how different pets interact. For example, if you also have a cat, a dog’s matting can sometimes be caused by a cat kneading or sleeping on them. It’s worth checking out resources like Are Norwegian Forest Cats Good With Dogs? What to Know if your cat and dog share a bed. A cat’s claws can snag loose hair and create tangles.

Step 4: When to Use Clippers

For mats that are too tight, too close to the skin, or located in sensitive areas (armpits, belly, behind the ears), clippers are the safest choice. Use a #10 or #7 blade, which is short enough to get under the mat without cutting the skin. Never use scissors near the skin. If you don’t own clippers or are nervous about using them, a professional groomer can do this quickly and safely. After clipping, the area will look a bit patchy, but the hair will grow back. It’s far better than leaving a painful mat. If your dog has a double coat, be aware that shaving can sometimes damage the coat’s ability to regulate temperature.

Step 5: Aftercare and Prevention

Once the mats are gone, give your dog a gentle brush all over to catch any remaining tangles. Then reward them with a favorite activity or toy. To prevent future mats, brush your dog at least three times a week, or daily during heavy shedding seasons. Focus on high-friction areas like behind the ears, under the collar, and the back legs. Use a conditioner spray before brushing to reduce static and tangling. Also, check your dog’s diet and overall health. Poor nutrition can lead to dry, brittle hair that mats more easily. If your dog has persistent matting despite regular brushing, ask your vet to rule out skin allergies or hormonal issues. And remember, if you ever feel overwhelmed, a professional groomer is always a great resource.
