Because brushing out a coat that has matted to the skin hurts, and a groomer's first job is not to hurt your dog. A mat is not a tangle: it is dead hair felted tight against living skin, and every brush stroke pulls on it. Where a comb cannot reach the skin, the kind answer is to clip beneath the mat and start again.
What is the difference between a knot and a mat?
A knot is a few hairs twisted together that a comb can work through in a minute. A mat is what a knot becomes when it is left: shed hair that should have fallen out gets trapped, new hair grows into it, moisture and friction felt the lot together, and the whole mass tightens down toward the skin. Run a comb into it and the comb stops well short of the body. That gap between where the comb stops and where the skin is tells the groomer everything. A coat that combs through to the skin, even slowly, can be brushed out. A coat that does not is matted, and the question is no longer how to save it but how to remove it safely.
Why does brushing out a mat hurt?
Think about a tight knot in your own hair at the scalp, then imagine someone working a brush through it for an hour. That is the dog's experience of a brush-out, except the mats are in the armpits, behind the ears, along the inside of the legs and around the tail, all the places where skin is thin and movement pulls on it constantly. Under a heavy mat the skin is often already sore: it has been pulled taut, kept warm and damp, and starved of air for weeks. Dogs put up with a great deal, but a long brush-out on skin like that is where patient dogs start to snap, and once a dog has learned that grooming means pain, every appointment after it is harder. That is the trade the groomer is refusing to make: a longer coat today for a dog that dreads the salon for years.
Why can't the groomer just clip through it?
Because a mat is a solid felt and a clipper blade will not pass through it. The blade has to go underneath, in the narrow space between the mat and the skin, which means the length of the coat afterwards is decided by how tight the mat was, not by the style you asked for. It is also slow, careful work. Matted skin is pulled up into the mat and can lift into the blade's path, so the groomer moves in short passes, checking constantly, and takes far longer over a matted dog than over a well-kept one. A teddy cut is not possible on a coat that has to be clipped to a few millimetres, however much everyone would prefer one.
What happens when a matted dog arrives at the salon?
At check-in the groomer will show you what they have found, usually with a comb in hand so you can see for yourself where it stops. Then you agree a plan before anything is done. If the mats are confined to a few friction spots, those can be clipped short and the rest of the coat blended in. If the matting is across the body, the coat comes off short and evenly, and the head, ears and tail are tidied so the dog looks finished rather than shorn. Matted coats take longer and are priced accordingly, which the groomer should explain up front rather than at pick-up. Afterwards the skin will be pink and tender for a few days, and your dog may scratch or shake as they get used to the air on it. Keep them out of strong sun, skip the beach until the skin has settled, and if there is any swelling or persistent head shaking, particularly after matted ears have been clipped, call your vet. Our salons at Jandakot and O'Connor take dogs of all sizes, and every groom starts with this kind of honest check of the coat.
Why do Perth coats mat so quickly?
Water and friction, and Perth has plenty of both. A cavoodle that swims at the river or the dog beach every weekend through summer, dries in the sun and goes home in a harness is being felted on a schedule. Spring brings grass seeds that catch in feathering and pull hair into knots around them. Winter brings damp coats that never quite dry between walks. Doodle and oodle coats mat fastest of all, because their soft, curly hair holds shed coat instead of dropping it, and the change from puppy coat to adult coat somewhere around their first birthday catches most owners out. Even a well-kept coat can go from fine to matted in the three or four weeks between a missed appointment and the next available one, which is why keeping to a grooming schedule matters more for these coats than for any other.
How do you stop it happening again?
Brush to the skin, not over the top of it. Most matted dogs are brushed regularly, but only the outer layer is being touched, and the felt builds underneath where nobody looks. After brushing, check with a comb: if it does not glide through to the skin, keep going or book in. Dry the coat properly after every swim and bath, because damp hair felts faster than dry. Choose a practical length for the season, since a shorter clip through summer is far easier to keep in good order on a dog that lives in the water. And if you have fallen behind, resist the urge to cut mats out with scissors: skin is pulled up into a mat and it is very easy to cut it. Book the appointment instead. Our guides to looking after an oodle coat and brushing at home cover the routine that keeps the comb passing through.
Frequently asked questions
Can you save some of the coat and just clip the matted bits?
Sometimes. If the mats are only in a few friction spots such as the armpits, behind the ears or under the collar, those areas can be clipped short and the rest of the coat left longer and blended in. If the matting runs across the body or sits close to the skin all over, the coat has to come off evenly, because a patchwork of short and long looks worse than a tidy all-over clip.
Why does my dog look so different after a matted groom?
Because the length was set by the mat, not by the groomer. The clipper has to travel between the mat and the skin, so the coat ends up as short as the mat was tight. Dogs also carry more weight in a matted coat than owners realise, and a slim, short dog appears almost overnight. It grows back, usually within a couple of months.
Why is my dog scratching and shaking their head after the groom?
Skin that has been covered by a mat is suddenly exposed to air and touch, and the sensation is new. Mild scratching for a day or two is common. Persistent head shaking after matted ears were clipped, or any swelling of the ear flap, needs a call to your vet, because the blood vessels in a freshly released ear can be fragile.
How do I stop the coat matting again?
Brush to the skin, not over the top, and check with a comb: if it will not pass through to the skin, the coat is not brushed out. Dry the coat properly after every swim or bath, keep the grooming schedule short enough for the coat you want, and if you have fallen behind, book an appointment rather than reaching for the scissors.
