FURminator vs Undercoat Rake: Which One Actually Stops the Shedding?

Both promise to end shedding. Both cost about the same. I tested both on Rex and Luna for 6 months. Here's which one actually works, and why most people pick wrong.

You walk into Petco. Two tools claim to “stop shedding 90%.” Both cost $25-35. One has plastic teeth that look like a comb. The other has a metal blade.

Which one actually works?

I’ve used both on Rex (German Shepherd, sheds enough fur to build a second dog) and Luna (Golden Retriever, somehow worse) for over a year.

The answer: they’re not the same tool. They do different jobs.

The 30-second verdict

Undercoat rake: breaks up the dense undercoat layer. Use first, more often, on double-coated breeds.

FURminator-style deshedding tool: removes loose surface hair after the rake has done its work. Use less often, more carefully.

Best practice: own both. Use the rake first, FURminator second. Together they remove 80%+ of dead coat. Either alone is half the job.

What each tool actually does

Undercoat rake

Long metal teeth, widely spaced, designed to penetrate through the topcoat into the dense undercoat layer where most shedding originates.

Mechanism: pulls dead undercoat hair out without cutting. Similar to combing.

Risk to dog: low. As long as you don’t dig hard into the skin, dogs find this comfortable.

Best for: Golden Retrievers, German Shepherds, Huskies, Akitas, Newfoundlands, Border Collies. Any breed with a dense undercoat.

FURminator (deshedding tool)

Short metal blade with tiny teeth, similar to a horse currycomb but finer. Designed to grab loose surface hair from the topcoat.

Mechanism: a small blade cuts and captures loose hair as you stroke. The cutting action is gentle but real.

Risk to dog: moderate if overused. Can damage the topcoat with too-frequent use or too-aggressive technique. Don’t use on undercoat directly. It’s designed for surface hair.

Best for: most shedding breeds, but especially short-coated dogs (Labs, Beagles, Boxers).

Head-to-head test

I tested both during peak shedding season on Rex. Same week. Same dog. Different tools.

Day 1: Undercoat rake only. 8-minute session. Pulled out an entire pile of dead undercoat about the size of a small dog. Coat felt dramatically lighter.

Day 2: FURminator only on Luna (no prior rake). 10-minute session. Pulled out a moderate amount, but the densely packed undercoat was still trapping the deeper layer. Coat still felt heavy.

Day 3: Rake + FURminator on Rex. 15-minute session. Massive output, about 1.5x what each tool produced solo. Coat felt completely different. Visible reduction in shedding for the next 5-7 days.

Conclusion: They’re complementary, not competitive. Used together, the result is roughly 40% better than either alone.

When the FURminator wins

  • Short-coated dogs (Beagles, Labs, Pit Bulls)
  • Dogs with single coats (Poodles get a slicker brush, not either of these)
  • Light-shedding breeds where surface hair is the only issue
  • You want one tool, not two

When the undercoat rake wins

  • Double-coated breeds (Goldens, GSDs, Huskies)
  • Heavy shedding seasons
  • Dogs whose coat looks “fluffy” and stays that way even after grooming
  • You’re new to grooming and want the safer option

When you need both

  • Heavy double-coated breeds
  • Spring or fall shedding peaks
  • Shedding has gotten worse recently
  • You’re committed to actually managing the shedding instead of just slowing it

What about brushing alternatives?

Slicker brushes: great for surface mat prevention, not for serious deshedding. A slicker is the daily tool; the rake/FURminator are the weekly heavy lifters.

Rubber grooming mitts: decent for short-coated dogs and bath time. Not effective on double coats.

Pin brushes: good for long, flowing coats (Afghan Hounds, Maltese). Not for shedding management on double coats.

For my full breakdown across 6 brush types, see the deshedding brush review.

The actual technique

This matters more than the tool:

  1. Brush dry, never wet. Wet hair stretches and breaks.
  2. Start with the rake. Long, slow strokes with the grain of the coat. 5-8 minutes for a large dog. Stop when you feel the rake gliding without pulling much.
  3. Switch to the FURminator. Same direction, lighter pressure. Small areas at a time. 5-7 minutes.
  4. Stop while there’s still some coming out. Don’t go until “nothing comes out”, that means you’ve damaged the coat.
  5. Bath after. Heavy deshedding sessions before a bath help loosen even more.

Total time: about 15 minutes once a week during shedding season. Worth it.

The bottom line

Buy both. They’re $25-35 each. Together they save you from owning a Roomba you have to empty 4 times a day.

If you can only buy one and have a double-coated breed: undercoat rake. If you can only buy one and have a short-coated breed: FURminator.

Don’t buy a $10 deshedding tool. The blade is dull, it pulls hair, and your dog will hate every session.

Frequently Asked Questions

The real questions I get from other dog dads.

Is a FURminator or an undercoat rake better for double-coated dogs?
An undercoat rake is better for the deep undercoat layer. The FURminator is better for the surface loose hair on the topcoat. For maximum shedding control on a double-coated dog (Golden, German Shepherd, Husky), use the rake first to break up the undercoat, then the FURminator on top to capture loose hair. Each tool does a different job.
Can the FURminator damage my dog's coat?
Yes, if overused. The FURminator has small blades that cut surface hair if used too often. Limit to once a week max for short coats, every 1-2 weeks for double coats. Don't use it on dogs with delicate single coats (Yorkies, Poodles) at all.
How often should I use an undercoat rake?
2-3 times a week during shedding seasons (spring and fall), once a week the rest of the year. Unlike the FURminator, the rake doesn't cut hair. It just pulls loose undercoat out, so it's safe to use more frequently.
What's the difference between an undercoat rake and a slicker brush?
An undercoat rake has long, widely-spaced metal teeth designed to penetrate deep into a thick coat. A slicker brush has short, fine wire bristles for surface grooming. For Golden Retrievers, German Shepherds, and Huskies, you need the rake. For shorter or curly-coated breeds, the slicker is plenty.
Are FURminator alternatives worth the money?
Some are. The Furbliss and Wahl deshedding tools are roughly equivalent at a lower price. Avoid super-cheap '$8 deshedding tools' on Amazon. Most have dull blades that pull hair instead of releasing it, which hurts the dog.
