The catch: Give it a few sessions to get the stroke down.
The maker states: Made in USAThe maker states: it is made in the USA, with no qualifier. Under FTC rules, that claim has to mean all or virtually all of it is made here.
For a double-coated dog, yes: Huskies, shepherds, goldens, labs, corgis: the FURminator's steel edge reaches through the top coat and pulls out the loose undercoat a regular brush slides right over. That's the fluff that otherwise ends up woven into your couch.
Single coats: No. For a poodle, a doodle, a terrier or any single coat, there's no undercoat to pull, and the edge can rough up the coat that's there.

Your first session will look alarming
Expect a pile of fur big enough to build a second dog. Your dog is not going bald. That's dead undercoat that was headed for your floor anyway, just collected in one place instead of spread across the living room.
How to use it without overdoing it
Start with a dry coat. After a bath, wait until it's fully dry.
Work out any mats first with a slicker brush or a dematting comb. Never run the edge over a mat.
Brush with the grain, head to tail, in long strokes.
Light pressure. Let the tool's weight do most of the work. Pressing hard scrapes skin and cuts the top coat.
Stop when much less fur comes out per stroke. That's the signal, not the clock.
About once a week is plenty. More often can thin the top coat.
Skip it entirely on hot spots, scrapes or irritated skin. If the skin under the coat looks red or sore, that's a vet question; see when shedding isn't normal.
Get the right version
FURminator sells different sizes and two edges: one for short hair, one for long hair. The one on this page is the large-dog, short-hair version. Match both the size of your dog and the length of the coat, or the edge won't reach the undercoat properly.
Signs you're using it wrong
Cut guard hairs on the tool instead of soft, fluffy undercoat. Ease up.
A patchy or thin spot where you went over and over. Spread the strokes around.
Your dog leaves the room when you pick it up. Shorter sessions, more treats.
If the FURminator isn't the right fit
SleekEZ: for short and medium coats
A wave-pattern blade that pulls loose hair and debris from short and medium coats. The catch: it takes some technique to use well.
Maxpower Planet undercoat rake: for coat-blowing season
A two-sided rake with 9 teeth on one side for stubborn tangles and 17 on the other for thinning, with rounded teeth. Good for double coats when the undercoat is coming out in clumps. The catch: overuse can over-strip, and it's not for single coats.
Generally no. Shaving takes off both layers, and a double coat can grow back patchy. Deshedding removes only the loose undercoat and leaves the top coat in place. If you're thinking about a shave for a specific reason, ask your groomer or vet first.
FURminator makes cat versions. The same rules apply: dry coat, light pressure, short sessions, and stop the moment your cat objects. Cats will let you know.
How often during heavy shedding season?
Stick close to once a week, and pick up a regular brush between sessions. If you're tempted to go daily, the edge is the wrong tool for that job.
Bottom line
In short
Double coat: buy the right size and edge, go light, once a week. Single, curly or wiry coat: leave it on the shelf and get a brush made for that coat.
