Reaches through the topcoat and pulls out the dead undercoat, which is the hair that ends up on your sofa. Sizing and light pressure are everything.

Best for Double-coated dogs over 50 lb with long hair
Key highlight Up to 90% less loose hair with regular weekly use

Brushes move loose hair around. This does something else: the stainless steel edge reaches past the topcoat and pulls out the dead undercoat that is actually responsible for the drifts of fur under your furniture.

What it does differently

A normal slicker brush works on the surface. The FURminator edge has fine teeth designed to pass through the guard hairs and catch the soft undercoat underneath, without cutting the coat or scraping skin. The first time you use it on a double-coated dog the quantity that comes out is genuinely startling, and that is hair that would otherwise have ended up on your clothes.

FURminator says regular use reduces loose hair from shedding by up to ninety per cent. Weekly is the recommended rhythm; during a seasonal coat change you will want to do it more often and outdoors.

Getting the right one

These are sized by animal weight and coat length, and buying the wrong one is the most common mistake. The large long-hair model is for dogs over fifty pounds with a coat longer than two inches, with a four-inch edge. There are short-hair versions, medium versions, and separate cat tools. Using a long-hair tool on a short coat is uncomfortable for the animal and ineffective.

Technique

Light pressure, in the direction the coat lies, in short strokes. The temptation is to press hard and rake, and that is how you get skin irritation. It is a tool for removing loose undercoat, not for detangling — work mats out with fingers or a proper dematting comb first, or you will hurt the dog.

Do not use it on a dog without an undercoat. Single-coated breeds and poodle crosses get nothing from it except a damaged coat.

The FURejector

A button on the handle pushes the collected hair off the edge in one motion, so you are not picking clumps out of the teeth every thirty seconds. It is a small mechanism that makes a long grooming session tolerable.

Should you buy it?

Buy it if you have a double-coated dog or a heavy-shedding cat and you are tired of the hair. Skip it if your animal is single-coated, if their coat is matted and needs proper detangling first, or if you cannot commit to using it weekly — occasional use does very little.

Frequently asked questions

Match your animal's weight and coat length. The large long-hair model is for dogs over 50 pounds with coats longer than two inches. The wrong size is uncomfortable and ineffective.

No. Breeds without an undercoat, including poodles and many crosses, get no benefit and the tool can damage the coat.

Weekly for most dogs, more often during a seasonal coat change. Occasional use does very little.

Not with light pressure in the direction of the coat. Pressing hard or raking the same spot repeatedly causes skin irritation, which is the usual complaint.

No. Work mats out with fingers or a dematting comb first. Dragging this through a mat is painful.
