Long-haired dogs shed in a way that coats furniture, clothing, and the very air of your home, and no amount of vacuuming keeps pace during a seasonal blowout. The FURminator Large Dog Undercoat deShedding Tool for Long Hair has become the reference standard for pulling loose undercoat before it lands on your couch, and we spent a full shedding season testing it on a Golden Retriever and a Bernese Mountain Dog.
The premise is simple: a stainless steel edge reaches through the topcoat to catch the dead, downy undercoat that ordinary brushes glide over. In this review we cover how well it works, how it is built, and whether it earns its higher price against cheaper deshedding rakes.

Design & Build

The tool centers on a fine stainless steel edge set into a wide head sized for large breeds. The handle is contoured rubber that stays grippy even when your hand is damp from a post-bath session, and a FURejector button pops the collected fur off the teeth with one press, which is oddly satisfying and keeps you from picking clumps out by hand. Build quality feels premium, with no flex in the head and a securely seated edge. This is the long-hair version, meaning the teeth are longer to penetrate a deeper coat than the short-hair variant.
Performance
Results are dramatic on the first pass. Working in the direction of hair growth, the tool lifted visible handfuls of undercoat within minutes, and a ten-minute session noticeably reduced the fur left on our test blanket over the following days. The key is restraint: because it is so effective, over-brushing the same spot or pressing too hard can irritate skin, so short, gentle strokes are the right technique. It is not a detangler, so badly matted coats should be worked out with a rake or comb first, then finished with the FURminator.
Pros & Cons
- Removes loose undercoat far more effectively than standard brushes
- FURejector button clears trapped fur instantly
- Comfortable non-slip handle sized correctly for large dogs
- Durable stainless edge holds up over years of use
- Higher price than basic deshedding rakes
- Can irritate skin if used too aggressively or on the same area repeatedly
- Does not remove mats, so pre-detangling is needed on tangled coats
Alternatives to Consider
If your dog has stubborn tangles as well as shedding, pair or replace it with the FURminator Dog/Cat Grooming Rake, which is built specifically to work through knots. Budget shoppers can look at the Maxpower Planet Dog Grooming Rake at $13.99 for basic undercoat removal, though it lacks the FURejector and refined edge. For matted long coats, the Docrok Pet Grooming Combo pairs a deshedding brush with a metal dematting comb.
Frequently Asked Questions
How often should I use it?
Once or twice a week during normal periods, stepping up to every couple of days during spring and fall coat blows. Limit each session to 10 to 20 minutes to avoid over-brushing.
Will it cut or damage my dog’s coat?
Used correctly on the undercoat with light pressure, no. Problems arise only from digging into the skin or repeatedly stroking one spot. Let the tool do the work rather than forcing it.
Is the long-hair version right for my dog?
Choose the long-hair model for coats over about two inches, such as Goldens, Bernese, and Collies. Short-haired breeds like Labs and Beagles do better with the short-hair edge.
Can I use it on a wet coat?
It works best on a clean, dry coat. Bathe and fully dry your dog first, since wet fur clumps and reduces how much undercoat the edge can catch.
Verdict
The FURminator long-hair deshedding tool remains the gold standard in 2026 for a reason: nothing in our test pulled undercoat as efficiently. At around $35 it costs more than a basic rake, but its durability and results make it a genuine long-term investment for any long-haired dog owner tired of living in a fur storm. Just use a light touch and detangle first, and it will earn its keep every shedding season.
