If you own a heavy-shedding dog, you’ve probably heard of the Furminator. Maybe you’ve watched videos of groomers using it and wondered, “Is that tool actually worth it, or is it just hype?”
I tested the Furminator deshedding tool extensively with my own heavy-shedding dogs. Here’s the honest truth.
What Is the Furminator?
The Furminator is a specialized grooming tool designed to remove loose undercoat hair from dogs and cats. Unlike regular brushes that mainly tackle surface fur, the Furminator’s stainless steel blade penetrates deep into the undercoat to grab hair that’s ready to shed but still attached.
The company’s claim: Reduce shedding by up to 90% with regular use.
Reality: For most heavy-shedding breeds, this isn’t far from the truth.
How the Furminator Works
The Furminator uses a patented blade design with tiny teeth that reach through the top coat into the dense undercoat. As you pull the tool, it grabs loose hair that would otherwise end up on your furniture, floor, and clothes.
Key features:
- Stainless steel deshedding blade
- Ergonomic handle for comfort
- Curved edge follows pet’s body
- Self-cleaning rake button
- Various sizes for different breeds

My Testing Process
I used the Furminator Large Dog DeShedder on two dogs over 8 weeks:
- Max: 6-year-old Golden Retriever (heavy shedder)
- Bella: 4-year-old German Shepherd mix (moderate-heavy shedder)
Week 1-2: Initial Assessment
First sessions were… shocking. In 20 minutes with Max, I collected what looked like enough fur to make another small dog. Bella’s session produced similar results.
Week 3-4: Establishing Routine
After three sessions per dog (about 15-20 minutes each), I noticed the fur balls were getting smaller. The tools were still pulling out plenty of hair, but less than the initial sessions.
Week 5-6: Results Evaluation
Furniture fur decreased noticeably. Vacuum bags lasted longer. My black jeans were actually wearable again.
Week 7-8: Long-term Effects
Weekly 15-minute sessions kept both dogs well-groomed. Shedding didn’t stop—nothing stops shedding completely—but it became manageable.
Pros of the Furminator
Dramatically Reduces Shedding
This is the main event, and the Furminator delivers. Regular brushing with this tool removes an enormous amount of loose fur before it ends up everywhere else.
Reaches Deep Undercoat
Regular brushes and combs don’t reach the undercoat effectively. The Furminator’s teeth penetrate where it matters.
Self-Cleaning Feature
The ejector button releases collected hair from the blade. No more picking fur out with your fingers.
Multiple Sizes Available
From tiny cats to giant breeds, there’s a Furminator designed for your pet’s size.
Cost-Effective Over Time
The tool pays for itself quickly. One Furminator replaces multiple brushes and reduces vacuum bag/filter replacements.
Professional Results at Home
Groomers use Furminators because they work. Now you can get similar results without professional grooming costs.
Cons of the Furminator
Requires Proper Technique
Using too much pressure or going against the grain can irritate your pet’s skin. You need to learn the right approach.
Not for All Coat Types
The Furminator works best on double-coated breeds. Single-coated dogs with continuously growing hair (Poodles, Shih Tzus) should use different tools.
Can Cause Skin Issues If Overused
Daily use is too much. Even heavy shedders need breaks. Over-brushing can cause skin irritation or remove too much protective undercoat.
Some Dogs Hate It
The sensation is intense. Some dogs tolerate it well; others learn to hide when they see you grab it.
Hair Gets Everywhere
Despite the ejector button, brushing releases fur into the air. Brush outside or in an easy-to-clean area.
Cheap Imitations Don’t Work
Only genuine Furminator products have the proper blade technology. Cheap knockoffs can damage coats or fail to work.
How to Use the Furminator Correctly
Using the Furminator properly makes a huge difference:
Step 1: Choose the Right Size
Too small = inefficient. Too large = hard to control. Match blade size to your pet’s body.
Step 2: Brush in the Right Direction
Always brush WITH the fur growth, never against it. Go with the natural direction of the coat.
Step 3: Use Light Pressure
Let the blade do the work. Pressing too hard doesn’t remove more fur—it irritates skin.
Step 4: Work in Sections
Divide your pet’s body into sections. Work methodically so you don’t miss areas.
Step 5: Don’t Overdo It
Limit sessions to 15-20 minutes. Skip areas you’ve already covered in a session. Use every 1-4 weeks depending on shedding intensity.
Step 6: Reward Your Pet
Make grooming a positive experience. Treats, praise, and patience go a long way.

FAQ: Furminator Questions
How often should I use the Furminator?
For most heavy shedders, every 1-2 weeks is ideal. Daily use is too much. During heavy shedding seasons (spring/fall), weekly may be necessary.
At what age can I start using the Furminator on my puppy?
Wait until your puppy’s adult coat comes in fully, usually around 6-9 months. Puppies have softer undercoats that the Furminator can damage.
Does the Furminator hurt my dog?
When used correctly with light pressure and with-the-grain strokes, the Furminator shouldn’t hurt. It may feel intense, but shouldn’t cause pain. Stop immediately if your dog shows signs of discomfort.
Can I use the Furminator on wet fur?
No. Always use on dry fur. Wet fur tangles and can damage the tool and your pet’s coat.
How do I know if my Furminator blade is dull?
Dull blades don’t pull out hair effectively—they just push fur around. You’ll notice decreased performance even with proper technique.
What’s the difference between the Furminator and a regular de-shedding tool?
Genuine Furminator products use patented blade technology specifically designed for undercoat removal. The tooth spacing, blade angle, and materials are engineered for this purpose. Cheap imitations often lack the proper design and can damage coats.
Final Verdict
Rating: 4.5/5
The Furminator deshedding tool genuinely works. If you live with a heavy-shedding double-coated dog, this tool can transform your relationship with pet hair.
It’s not magic—nothing stops shedding completely—but it removes the bulk of loose undercoat that would otherwise coat your home.
Bottom line: If you’re tired of fighting a losing battle against dog fur, the Furminator is worth the investment. Your vacuum (and your black pants) will thank you.
