Dog Matting: Why Groomers Shave Matted Dogs and How to Prevent It

If the comb already stops at the skin, severe dog matting hurts and traps moisture, so groomers often shave rather than brush out tight knots. So the “humanity over vanity” rule means a shorter welfare clip beats hours of painful dematting. Prevent mats with regular brushing between professional grooms.

If you’ve picked up your dog and found them shaved when you expected length, you’re not alone. When mats are tight to the skin, shaving is often the only safe option.

What is matting?

Matting occurs when loose, dead hair tangles with live hair and forms tight knots close to the skin. These knots become progressively tighter over time, pulling on the skin and creating painful pressure points.

Where matting happens:

• Behind the ears – Friction from collars and movement
• Armpits – Rubbing from leg movement
• Under the tail – Friction from sitting and movement
• Belly – Rubbing against the ground when lying down
• Legs – Especially the “feathers” on long-haired breeds
• Chest – Where the collar or harness sits

According to the RSPCA Australia, matting is a health problem that can cause pain, skin infections, and restricted movement.

Why groomers shave matted dogs

The grooming industry uses a rule called “humanity over vanity” – meaning a dog’s comfort and safety always come before their appearance. Here’s why shaving is necessary:

The shaving process:

• Groomers use a #10 or #7 blade (very short) to get under the mat
• The mat is shaved off in one piece, minimising pulling
• The process takes 30 – 60 minutes (vs 4–6 hours of painful brushing)
• Your dog can have minor nicks or irritation, but this is far less painful than brushing

If a groomer says they must shave, they’re usually choosing welfare over the photo you saved. Dematting and welfare clip-downs are part of a full groom when the coat is felted; see what is included in dog grooming. Argue after the dog is comfortable, not while they’re still on the table.

Health risks of severe matting

Severe matting causes serious health problems:

• Skin infections – Trapped moisture and bacteria lead to infections
• Hot spots – Irritated skin can develop into painful sores
• Restricted movement – Tight mats on legs or joints limit mobility
• Parasites – Fleas and ticks can hide under mats
• Pain – Constant pulling on the skin causes discomfort
• Circulation issues – Tight mats can restrict blood flow

According to the RSPCA Australia, severe matting can lead to medical complications requiring a vet.

Mats pull skin, hide sores, and turn a collar into a tourniquet. That’s welfare, not a cosmetic fail. A short clip can look shocking on pickup and still be the kind option. Owners who insist on “just brush it out” while the dog screams are asking for injury.

How to prevent matting

Prevention is always better than cure. Regular brushing plus a professional groom on a sensible schedule (see how long between dog grooms and how often to wash your dog) keeps most coats mat-free. Here’s how:

Brushing frequency by coat type

How to brush properly

Step 1: Start with a slicker brush

• Brush in the direction of hair growth
• Work in small sections, starting at the skin and brushing outward
• Pay attention to high-friction areas (behind ears, armpits, under tail)

Step 2: Use a comb to check

• After brushing, run a comb through the coat
• If the comb gets stuck, there’s still a mat, so go back with the brush
• The comb should glide smoothly through the entire coat

Step 3: Use detangling spray if needed

• Spray a pet-safe detangling spray on tough areas
• Work the spray into the coat with your fingers
• Brush gently to remove tangles

Where to focus your brushing

Spend extra time brushing these areas:

• Behind the ears – Brush daily, as this area mats quickly
• Armpits – Lift the leg and brush thoroughly
• Under the tail – Check and brush after each bathroom break
• Belly – Brush when your dog is lying on their back
• Leg feathers – Long hair on legs tangles easily

What to do if your dog is already matted

When you discover mats in your dog’s coat:

• Don’t try to brush them out if they’re tight to the skin. That causes pain and can tear skin.
• Book a grooming appointment – Groomers have the tools to safely remove mats
• Be prepared for shaving – If mats are severe, your groomer will need to shave them
• Expect extra costs – Dematting fees range from $15-$30 per 15 minutes of work
• Be patient – Hair will grow back, usually within 2–3 months

When your dog is severely matted and you can’t afford a groomer, contact your local RSPCA for guidance.

The cost of matting

Preventing matting is much cheaper than treating it:

Regular brushing at home costs nothing and prevents these expensive problems.

Demat blocks at $15–$30 per 15 minutes add up faster than a 5-week Cavoodle diary. A welfare shave may cost less than two hours of combing a felted coat. Budget the interval, not the rescue. That’s the only way the invoice stays boring.

Tools for preventing mats

Invest in quality grooming tools:

• Slicker brush – Main tool for removing tangles ($15-$30)
• Metal comb – Use to check for remaining tangles ($10-$20)
• Undercoat rake – For double-coated breeds ($15-$25)
• Detangling spray – Helps with tough tangles ($10-$20)
• Pin brush – For long, silky coats ($15-$30)

Total investment: $50-$100 for tools that will last years and save you hundreds in dematting fees.
