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

Dog Matting Dog matting occurs when loose hair tangles and forms tight knots close to the skin. Groomers must shave matted dogs because attempting to brush out severe mats causes pain, skin damage, and risks cutting the dog's skin. The "humanity over vanity" rule means a shaved dog is better than a dog in pain. Prevent matting by brushing your

If you’ve ever picked up your dog from the groomer and been shocked to see them completely shaved, you’re not alone. Many pet owners are surprised, and sometimes upset, when their long-haired dog comes back looking like a short-haired breed.

But here’s the truth: when a dog is severely matted, shaving is the only safe option. Attempting to brush out tight mats causes excruciating pain and can lead to serious skin damage. In this guide, we explain why groomers shave matted dogs, how to prevent matting, and what you can do if your dog is already matted.

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 tells you they must shave your dog, trust their professional judgment, as they’re prioritising your dog’s welfare over aesthetics. Dematting and welfare shave-downs are part of a full groom; see what is included in dog grooming.

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.

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

Whenou discover mats in your dog’s coat:

• Don’t try to brush them out – This causes pain and can damage the 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

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