Matted dog hair is more common than many pet owners realize, and it can happen faster than you might expect.

Our pet groomers at Impawsible Pups have seen it before: what may start as a small tangle can quickly turn into tight, dense mats that are difficult and sometimes painful to brush out. While matting is often seen as a grooming issue, it can also impact your dog’s comfort, skin health, and overall well-being.

Understanding why matting happens, how to prevent it, and when to seek professional help can make a big difference in keeping your dog comfortable and cared for!

What is Matted Dog Hair?

Matted dog hair is made up of knots that tangle together to create dense, tightly clumped areas of fur. While small tangles can usually be brushed out, matted fur typically can’t. Some coat types naturally mat more easily than others, and a big part of that comes down to the difference between hair and fur.

Dogs with hair (like poodles) typically have single-coated, continuously growing strands that stay rooted in the follicle rather than shedding out. Because this hair doesn’t fall away on its own, loose strands get caught in the surrounding coat, making it much easier for tangles to form and tighten into mats over time. Coats that are curly, dense, or cotton-like are especially prone to matting, as curly hair naturally wants to clump together. Brushing through these knots can also cause discomfort due to pulling and tugging.

Dogs with fur (often double-coated breeds like Australian Shepherds) have a shedding cycle. Their undercoat naturally releases, which can help prevent some matting, but only if that loose fur is properly brushed out. If not, it can get trapped in the topcoat and create dense tangles or what’s known as pelting. While these dogs may be less prone to matting overall, they still need regular brushing or blow drying to help release that undercoat. The undercoat naturally wants to come out, which can make brushing easier, but severe matting can still happen.

The Most Common Causes of Matted Dog Hair

The number one cause of matting is not brushing your dog.

That said, even your pups’ daily habits can result in their hair matting. For example:

  • Sleeping more frequently on one side
  • Friction in areas like the armpits while walking
  • Letting a dog air dry after a bath or swim without brushing

Any type of friction can contribute to tangles forming. The key to minimizing the risk of matted hair is to brush your dog regularly.

The Hidden Risks to Skin and Health

Matting isn’t just a cosmetic issue, it can actually impact your dog’s health, too.

When fur becomes matted, it can block your ability to see your dog’s skin. This makes it harder to notice things like warts, fleas, injuries, or skin conditions.

In more severe cases, tightly matted fur can restrict blood flow. This is most commonly seen on the ears, where matting on the thin skin of the ear (the pinna) can become too tight. When the matting is shaved away, blood flow returns quickly, which can cause blood vessels to burst and lead to hematomas. It’s also important to note that shaving a double-coated dog can damage their natural coat, which plays an important role in regulating body temperature.

While rare, there are extreme cases where prolonged restriction from matting has led to serious complications, including loss of circulation in extremities.

Can Matted Fur Impact a Dog’s Behavior?

Matted fur can be very uncomfortable and restrictive for your dog.

It can interfere with their natural ability to regulate body temperature and, in more severe cases, even limit movement or blood flow. Mats can form anywhere there is fur, between the toes, in the armpits, around the face, and near the ears, making everyday movement uncomfortable.

While we can’t say exactly how this affects behavior, it’s easy to imagine that a dog who feels restricted or uncomfortable may become more easily irritated or frustrated.

Why At-Home Brushing Isn’t Always Enough

Brushing at home is the only way to prevent matting, but it has to be done correctly.

If brushing isn’t thorough or the right tools aren’t used, matting can still happen. For most long-coated dogs, a slicker brush and comb are effective tools.

To properly prevent matting, brushing should be:

  • From root to tip
  • From head to toe (nose to tail)

When done the right way and consistently, matting shouldn’t occur. However, it’s important to understand that thorough brushing can take a significant amount of time, sometimes even hours, depending on the coat.

When Professional Grooming is Required

There are a few clear signs that it’s time to bring your dog to a professional groomer. If you’re feeling thick, dense clumps of fur, can no longer see your dog’s skin, or your dog seems uncomfortable when being brushed, matting has likely progressed beyond what can be safely handled at home.

When matting reaches this point, the safest and most comfortable way to remove it is typically by shaving it off. But when done at home, trying to cut or brush out matting yourself can lead to injury or create negative associations with grooming, which can make future care more stressful for your dog.

That’s where many pet owners rely on a trusted dog groomer to take care of their pet’s grooming needs. Clippers alone can’t cut through matted fur, they can only go underneath it. This is why your groomer may need to shave your dog shorter than expected, even if the matting seems isolated to just a few areas.

In some cases, minor knots can be worked through using tools like mat splitters and slicker brushes. However, your dog’s comfort is always the top priority when deciding the best approach.

The good news is: hair grows back!

How to Prevent Matted Fur Between Grooming Appointments

Preventing matting comes down to consistency and technique.

We recommend using a slicker brush and comb, starting from the feet and working your way up, parting the fur and brushing from root to tip in small sections. Then run a comb through your work to check it.

Areas that often get missed (but are important to include):

  • Armpits (lift the legs to reach underneath)
  • Between the toes
  • Around the face, mouth, and chin
  • Under and behind the ears
  • Around private areas
  • The stomach

You don’t have to keep every part of your dog’s fur long. If you prefer a shorter body, you can focus brushing on areas like the face, ears, and tail. But if you want a fuller coat, more thorough brushing is needed.

Creating a routine makes a big difference over time. Most dogs benefit from brushing every 1–3 days, depending on coat length. While some dogs may resist at first, consistency (paired with positive reinforcement) helps them adjust. When done properly, brushing should not be painful, and staying consistent will benefit both you and your pup!
