The Open Knot Dematting Comb is a dematting comb for dogs with a sharp blade that cuts through hair clumps and knots, helping to keep the coat smooth and tangle-free. Suitable for long and short coats, lightweight and easy to clean, it is designed for owners who want to deal with knots at home or on the go, before they turn into bigger mats.
If you are searching for a dematting comb for dogs in the UK, this guide explains how a bladed open-knot comb differs from a brush, which dogs it suits and, most importantly, how to use it safely.
What is an open knot dematting comb?
Ordinary brushes and combs try to tease tangles apart. That works for light knots, but tighter clumps can be uncomfortable to brush out and may just get pushed further down towards the skin. An open-knot dematting comb takes a different approach: it has a blade designed to cut through hair clumps and knots, breaking them up so the rest of the coat can be combed smoothly.
Because it uses a sharp blade, technique matters. Used carefully, a dematting tool can make knot removal quicker and more comfortable. Used carelessly, any bladed tool can catch the skin, so read the safety tips below before you start.

Which dogs need a dog mat remover?
Knots form when loose hair, friction and moisture combine. Some dogs are much more prone to them than others. This comb can be particularly helpful for:
- Long-coated breeds such as Spaniels, Setters, Collies and Retrievers, especially around the ears, legs and tail.
- Curly and wavy coats, including many doodle crosses, Bichons and Poodle mixes.
- Dogs who wear harnesses or collars, which can cause friction tangles where the straps sit.
- Dogs who love water and mud, as wet coats that dry without brushing often tangle.
Short-coated dogs can benefit too, particularly in areas where fur is longer or thicker, such as behind the ears and on the "trousers".
The multi-packs (5 or 10) are handy for households with several dogs, for keeping one in every grooming bag, or for sharing with family and friends.
How to use a dematting comb safely
Take your time and keep sessions short. As a general approach:
- Work on a dry coat. Detangle before a bath, not after – water tends to tighten knots.
- Find the knot with your fingers. Feel for the clump and identify where it ends and the skin begins.
- Hold the hair at the base. Grip the fur between the knot and the skin. This protects the skin and stops you tugging.
- Use short, gentle strokes. Draw the comb through the knot in the direction of hair growth, starting at the outer edge and working gradually inwards.
- Never drag it across the skin. Keep the blade working in the hair, not pressed against your dog.
- Finish with a brush or comb. Once the knot is broken up, smooth the area with a Self-Clean Slicker Brush, then check it with a fine comb such as our Double-Sided Metal Comb with Wooden Handle.
When to call a groomer or vet
Very tight mats that sit flat against the skin, large matted areas, or mats in delicate places such as the armpits, groin or face are best handled by a professional groomer. If you find red, sore, broken or smelly skin under a mat, ask your vet to check it. A home dematting comb is best for keeping on top of knots early, before they get to that stage.
Preventing knots between grooms
- Brush little and often, especially in tangle-prone areas.
- Dry and brush your dog after swimming or wet walks.
- Check under harnesses and collars regularly.
- Keep long-coated dogs on a regular professional grooming schedule if needed.
Care tips for your dematting comb
- Remove hair from the blade after each use.
- Wipe clean and dry thoroughly before storing.
- Store safely out of reach of children and pets, as the blade is sharp.
- Check the blade before each use and replace the comb if it is damaged.

Frequently asked questions
Is a dematting comb safe for my dog?
Used carefully, yes. Always hold the hair between the knot and the skin, use short gentle strokes and never drag the blade across the skin. Leave tight mats close to the skin to a groomer.
Does it work on short-haired dogs?
It is suitable for long and short coats, and is especially useful where fur is longer, such as behind the ears.
What is the difference between a dematting comb and a brush?
A brush teases tangles apart; a dematting comb has a blade that cuts through knots and clumps so they can then be brushed out.
Why buy a multi-pack?
Packs of 5 or 10 are handy for multi-dog homes, keeping spares in grooming bags, or sharing.
