The FURminator Undercoat deShedding Tool for medium long-haired dogs is a stainless steel edge on an ergonomic handle: a curved skin guard rides the dog while the comb reaches through the topcoat for loose undercoat, and a FURejector button pushes collected hair off the teeth. FURminator, a Spectrum Brands brand that dates its start to 2002, sells this size as SKU P-92914 for dogs 25 to 50 pounds and claims up to 90 percent less loose hair with regular use. Amazon charged $33.57 on 2026-10-04 — In Stock, shipped by Amazon and sold by Amazon.com, with a free 30-day refund or replacement.
Everything about the tool is a matching exercise: edge to weight band and coat length, session to the once-or-twice-weekly cadence, coat condition to the dry-and-mat-free requirement. A guarded edge used on the wrong dog or the wrong coat still meets skin it should not.
Our verdict
Buy the $33.57 Medium Long Hair tool for a 25-to-50-pound shedding dog and keep the weekly cadence; matted coats need a dematter first, and dogs outside the band need a different edge.
- A good fit for
- Owners of 25-to-50-pound long-haired shedding dogs who will run 10-to-20-minute sessions once or twice a week, on a dry, brushed-out coat.
- We would skip it if
- Skip it for non-shedding breeds, particularly sensitive skin, or a matted coat — the teeth can bend — and match dogs under 25 or over 50 pounds to the small or large edge instead.
Reasons to consider it
- The stainless steel edge carries a curved skin guard that the brand says glides over skin, keeps the tool from digging in at the edges of a stroke, and conforms to the dog's natural build
- A FURejector button pushes collected hair off the teeth mid-session, and pressing it while pulling back locks the built-in Edge Guard over the edge for cap-free storage
- Sizing is published as a clean matrix — small under 25 pounds, medium 25 to 50, large over 50, each with a Long Hair and a Short Hair edge — so matching the tool to the dog takes two facts, not guesswork
The compromises
- The no-cut claim is asterisked "when used as directed," and the directions themselves concede that deep or rough brushing can still irritate skin — pressure discipline stays with the hand holding the tool
- Undercoat is the whole scope: the FAQ excludes non-shedding breeds and particularly sensitive skin, and a matted or tangled coat needs a dematter or rake first or the teeth can bend or break
- The brand's anti-counterfeit page says the sold-by line is what to read before ordering, and the anchored offer's seller changed from Monster Pets on 2026-09-18 to Amazon.com by 2026-10-04, within about two weeks
What we have not verified: The edge's working width in inches appears nowhere — not on FURminator's product pages, not on the listing — so sizing rests entirely on the weight bands. Amazon's style menu shows the current edge, labeled "long hair - new model", beside older styles and a bundle, and nothing maps those styles to SKUs; the link to P-92914 rests on the matching weight band and coat length. The up-to-90-percent figure rests on the brand's regular-use wording, with no independent test behind it. The seller moved from Monster Pets on 2026-09-18 to Amazon.com on 2026-10-04 and 2026-10-05, and FURminator publishes no reseller list to check other sellers against.

A closer look at the products, who they may suit, and what to check before buying.

Undercoat deShedding Tool (Medium Dog, Long Hair)
$33.57 from Amazon on 2026-10-05 — In Stock, shipped and sold by Amazon.com — buys a guarded stainless edge sized to dogs 25 to 50 pounds with long hair, a FURejector button that clears hair mid-session, and an Edge Guard for cap-free storage.
Before you buy: The no-cut claim holds only when used as directed: dry coat, mats removed first, gentle strokes, no sensitive skin. Dogs outside the weight band need the small or large edge.
Price checked September 19, 2026. Retailer prices can change.The edge and the asterisk
The headline claim runs: a stainless steel deShedding edge that reaches through the topcoat to safely and easily remove loose hair and undercoat without damaging the topcoat or cutting the skin — with an asterisk, when used as directed. The same page defines directed use. Work like a brush, in the direction of hair growth, teeth angled toward the coat, starting at the head and working back, with extra care near the stomach, legs, genitals and anus. Fewer long, gentle strokes up and away from the skin; no excessive stroking in one spot.
The asterisk points at real conditions. The directions concede that deep or rough brushing can still irritate pet skin even with the skin guard, so pressure stays limited and any redness or irritation ends the session. That curved guard is the engineering under the promise — it glides over skin, keeps the edge from digging in at the ends of a stroke, and conforms to the dog's build — but a guard plus a heavy hand still lands on the dog. The FAQ draws the boundary around the claim: most animals that shed qualify, while non-shedding breeds and particularly sensitive skin do not.
One design, six dog variants
Three sizes, two coat lengths: small for dogs under 25 pounds (SKU P-92924), medium for 25 to 50 (P-92914), large for over 50 (P-92926), each offered with a Long Hair and a Short Hair edge; cats get their own small and medium-to-large pairs. Toy and giant dog sizes survive only in the legacy catalog. Nowhere on these pages does an edge width in inches appear — the weight band and the coat length are the whole published sizing system.
Amazon's listing arranges the same choice as style and size menus. The render showed "long hair - new model" as this tool's style, older "long hair" and "short hair" styles beside it, a Deshedding Bundle, one option with no featured offers, and sizes running Small, Medium, Large and a Large Pack of 12. FURminator's instruction is blunt — match the weight band, then match the coat length. A 40-pound short-coated dog belongs on the Short Hair edge in the same listing; a 60-pounder on the large page.
Ten to twenty minutes, once or twice a week
The FAQ schedule reads one to two sessions a week, 10 to 20 minutes each, varying with breed, coat condition and thickness, with more frequent sessions during heavy shedding seasons; a shorter line on the same page reads deShed weekly. Timing carries a condition: any time on a completely dry coat, ideally immediately after washing or drying. Preparation comes first in the directions — a full inspection for sores, bruises and skin conditions, with a veterinarian before brushing if any turn up, and tangles or mats removed with a dematting tool or grooming rake before the edge touches fur.
Mats are the teeth's stated enemy: work the tool over matted or tangled fur and the teeth can bend or break, besides hurting the dog. Aftercare is short — warm water and mild soap when dander collects on the edge, a complete dry before storage, and the built-in Edge Guard locked over the teeth by pressing the FURejector button and pulling back, which stores the tool without a cap. The FURejector does double duty mid-session, pushing accumulated hair off the teeth so the session keeps moving.
Fakes, sellers, and a recall next door
Counterfeit deShedding tools circulate on auction, forum and marketplace sites — the brand's Stop the Fakes page names eBay, Craigslist and Amazon marketplaces — and in its words often do not work properly and are known to break easily, creating the potential to seriously injure both pets and people. The page's advice is seller hygiene: beware resellers whose inventory is mostly non-pet goods, sellers moving only deShedding tools, discount-FURminator marketing, and domains that misspell the brand. Its sharpest tool is the sold-versus-shipped distinction: Amazon may ship an order while an unrelated store is the one actually selling it.
On the anchored offer that check now comes back clean: as read on 2026-10-04 Amazon ships and sells it. The warning still earns its place, because the same listing carries older style entries and a bundle, and the brand publishes no reseller list to check a different seller against. The brand cannot refund counterfeits and asks buyers who suspect one to send purchase details and photographs through its Catch the Crooks form. One scoping note for blurred search results: the June 2024 CPSC recall covered the one-gallon deShedding Ultra Premium Dog Conditioner, about 102,000 containers over bacteria risk — a liquid, not this tool.
Who should skip it
FURminator's exclusions write most of the skip list: non-shedding breeds and pets with particularly sensitive skin should not use the tool at all; a dog with sores or a skin condition needs a veterinarian before any brushing; a matted coat goes to a dematter or rake first, and heavy matting is a groomer's job rather than a weekly edge's. Sizing cuts another slice — dogs under 25 or over 50 pounds belong on the small or large version, not this one.
Scope does the rest. This edge pulls loose undercoat on the dog, and the up-to-90-percent reduction figure is the brand's regular-use claim — the weekly session above is what regular means. Hair already on the couch is the couch tool's problem; a reusable roller covers that side without involving the animal. An owner unwilling to spend twenty minutes a week on the coat is outside the condition the claim is written on.
