Dog matted: what to do about knots, mats and a short clip

You can carefully work out single, still loose knots at home: start from the outer edge, hold the matted fur with one hand, and work in short sessions. Solid mats belong in the salon, as the PDSA advises against tackling matting at home. Here in Charlottenburg, we'll quote you the price after a personal assessment. We charge 15 € per started 15 minutes on top of the booked groom. The Full Groom starts at 79 €.

How does matting form in a dog's coat, and why is it a problem?

Matting often forms where fur rubs against itself. The American Kennel Club gives the example of where the front legs meet the chest. Sometimes matting starts at a damp spot or from a bit of dirt picked up on a walk. According to this description, the tangle turns into a clump of hair that's barely possible to work through.

Matted fur can irritate the skin and lead to infections, according to the MSD Veterinary Manual. It also notes that regular brushing removes loose hair and helps prevent matting. This is especially important for thick or long coats. The PDSA points out that pets shed more in spring and autumn and need extra grooming during these times.

How to spot matting in your dog's coat

You can spot matting by firm clumps of hair that feel like hard patches when you stroke your dog. The American Kennel Club describes matting as a clump of hair that's barely possible to open up. So start by checking the friction points, such as where the front legs meet the chest. Also check any areas that have gotten wet or where dirt has stuck in the fur.

When checking, keep an eye on the skin too. The American Kennel Club describes irritated spots as bald or thinly-haired patches with red, dry, flaky or smelly skin, sometimes with scabs. If a spot like this hasn't healed within a few days, it needs a vet's attention. The PDSA generally recommends discussing any changes to skin and coat with your vet.

We'll tell you the price for the groom after a personal assessment. The six steps of an appointment are described on our What to expect at your appointment page.

Gently working out small knots at home

You can work out a single knot yourself, as long as your dog stays relaxed while you do it. The American Kennel Club describes the technique like this: start at the outer edge of the matted fur and work your way towards the body. Hold the mat firmly with one hand and loosen the edge with a de-matting tool, such as a mat pick. The hand holding the fur absorbs the pull, so your dog doesn't feel it on their skin.

A knot doesn't need to disappear in one day. The American Kennel Club recommends working on it for a few minutes at a time, spread over several days. The PDSA suggests taking it slowly and stopping as soon as your dog seems restless or stressed. Reward them during and afterwards, so the experience stays a positive one.

That said, the PDSA advises against tackling matted fur yourself and recommends a qualified groomer instead. In practice, this means: you can gently work out single soft knots yourself, but firm mats are best left to experienced hands.

Mistakes to avoid with matted fur

Three things matter when it comes to matted fur: no scissors near the skin, keeping an eye on damp patches in the coat, and using a tool suited to the coat type.

The MSD Veterinary Manual specifically advises against removing mats with scissors, as it's easy to accidentally cut the skin. Electric clippers for pets are recommended instead.

The second point concerns water. According to the PDSA, curly coats on poodle mixes like cockapoos and labradoodles tend to mat more easily when wet. The American Kennel Club also notes that matting can start at a damp spot in the coat.

The third point is the tool itself. The American Kennel Club matches it to coat type: rubber brushes for short coats, slicker brushes for dense coats, combs for long coats. If your dog is shedding a lot of undercoat, the soft layer beneath the topcoat, they also recommend an undercoat rake or a de-shedding brush.

When does a matted dog need to go to the salon?

It's time to bring your dog to the salon once the matting is more than just a few loose knots. The PDSA advises against dealing with matted fur yourself and points you towards a qualified groomer. These signs suggest it's time for an appointment:

1. The matting lies flat against the skin and can no longer be moved by hand.
2. Several knots have formed in sensitive areas such as the armpits, belly or base of the tail.
3. Your dog pulls away or shows discomfort as soon as you touch the area.
4. The coat got wet and then tangled up as it dried.
5. Your comb and detangling tool just can't get through anymore in that spot.

If the skin under the matting is red, smells unusual, or is weeping, the first step is a trip to the vet. Only after that do we plan the grooming. The MSD Veterinary Manual says the same applies if there's severe itching or hair loss.

Dematting or clipping: what's better for severe matting?

With very severe matting, we often recommend a short clip, as it's gentler on the dog and more affordable. We only offer clipping for breeds whose coat allows it, such as poodles, doodles, bichons, Maltese or Yorkshire terriers. We don't shave breeds with an undercoat, like spitz, Pomeranian, husky or golden retriever. For those, we work the mats out by hand.

We never pull on mats. We work carefully, step by step, with breaks along the way, and if the coat is badly matted, we'll talk through the best solution with you. The products we use depend on coat type and skin condition. For the cut lengths possible after a short clip on poodles and doodles, have a look at our article Teddy-Cut for poodles and doodles.

How much does de-matting cost at a dog groomer in Berlin?

Light knots are included in the price of the groom. For badly matted coats, we charge €15 per 15 minutes started on top of the booked service. You'll find all our starting prices on the Prices page.

We let anxious dogs settle in first, no pressure, no force. You can read how an appointment with a nervous dog goes in our article Anxious dog at the groomer's. You can book round the clock here: Book an appointment online.

How do you stop new mats from forming?

You can prevent new matting with regular brushing and fixed salon appointments. The PDSA recommends daily brushing for long-haired breeds, several times a week for medium-haired breeds, and once a week for short-haired breeds. Poodle crosses like cockapoos and labradoodles are specifically mentioned as prone to matting, needing brushing several times a week.

You'll find the right interval between salon visits for your breed in our article How often to visit the dog groomer. For a detailed guide on which brush to use, how to use it, and which spots to check daily, see Preventing matting.
