Doodle owners learn the same lesson the hard way: a curly coat can look fine on the surface for weeks while it quietly felts underneath. Curved cutting blades set in rows are what get into that, slicing a knot open from the side instead of yanking it out whole. Nothing is dragged through to the skin, so the dog is not braced against you the entire session.

The handle is moulded with a ridged spine along the top, which is why people call it the dinosaur comb, and those ridges are there to stop a wet or soapy hand sliding forward onto the blades mid-stroke. Grip matters more here than on an ordinary brush, because dematting is done with a short, controlled pull rather than a long sweep, and control is what keeps the blade away from skin. Green, white and blue are offered.

• Rows of curved cutting blades
• Slices knots open rather than pulling them out
• Ridged non-slip handle
• Suits long, curly and double coats
• Usable on dogs and cats
• Three colours: green, white and blue

Not a brush, and not self-cleaning. This is a bladed dematting comb, and the blades are sharp enough to cut skin if dragged across a fold. Keep it away from armpits, the belly and behind the ears, and keep it out of reach of children.

Who it's for: Owners of doodles, spaniels, long-haired cats and any coat that mats quietly between professional grooms.
