The FURminator Undercoat deShedding Tool for medium dogs with long hair is a stainless steel edge behind a curved skin guard, with a FURejector button that pushes collected hair off the teeth. Amazon Australia lists the US version, SKU P-92914 with barcode 811794929145 from Spectrum Brands Pet LLC, sized for dogs of 25 to 50 pounds, about 11 to 23 kg. On 5 November 2026 it was A$58.87, in stock, shipped and sold by Amazon AU, in the style labelled "long hair - new model".
Petbarn sells a different medium: barcode 4048422141068, described for long-haired dogs of 9 to 23 kg with fur of 5 cm or longer, at a regular A$70. Both carry the same conditions from the maker. The coat has to be completely dry and free of mats, the dog has to shed and have an undercoat, and the no-cut promise holds only when the tool is used as directed.
Our verdict
Buy the medium long-hair tool for a shedding, long-coated dog of roughly 11 to 23 kg and use it weekly on a dry, brushed-out coat. Amazon AU's A$58.87 undercuts Petbarn's A$70 for a near-identical job.
- A good fit for
- Owners of long-haired, double-coated dogs between about 11 and 23 kg who will brush once or twice a week for 10 to 20 minutes on a dry coat.
- We would skip it if
- Your dog does not shed, has particularly sensitive skin or a matted coat, or weighs outside the band, where the small or large edge fits better.
Reasons to consider it
- The stainless edge sits behind a curved skin guard that FURminator says glides over skin and stops the edge digging in at the ends of a stroke
- The FURejector button clears hair from the teeth mid-session, and an Edge Guard locks over the teeth for storage without a cap
- Amazon AU sells and ships it at A$58.87, and Petbarn stocks a medium long-hair version for A$70 with in-store pickup, so the tool is easy to buy from a retailer that answers for it
The compromises
- The no-cut claim is conditional on use as directed, and the directions concede that deep or rough brushing can still irritate skin
- Undercoat is the whole job: a matted coat needs a dematter first or the teeth can bend or break, and non-shedding breeds should not be brushed with it
- The two mediums on sale in Australia are coded differently and sized slightly differently, 25 to 50 lb on Amazon's US unit against 9 to 23 kg on Petbarn's
What we have not verified: FURminator runs no Australian product page, so the Amazon unit's directions come from the US maker page and Petbarn's from its own copy; nothing published says whether the two mediums use an identical edge. The up-to-90-percent figure is the brand's regular-use claim, and no edge width is given anywhere.
The things in this guide
A closer look at the products, who they may suit, and what to check before buying.
Undercoat deShedding Tool (Medium Dog, Long Hair)
A$58.87 with Amazon AU as seller buys the US medium long-hair edge, its skin guard and the FURejector button, at less than Petbarn's A$70 for its European-coded medium.
Before you buy: Mats come out first with a dematter or rake, sensitive skin and non-shedding breeds are off the list, and a dog under about 11 kg fits the small edge better than this one.

FURminator's claim is that the stainless edge reaches through the topcoat to remove loose hair and undercoat without damaging the topcoat or cutting the skin, and the asterisk on it reads when used as directed. The directions are specific. Work like a brush in the direction of hair growth with the teeth angled toward the coat, start at the head and work back, take extra care near the stomach, legs, genitals and anus, and use fewer, longer, gentle strokes instead of working one spot.
The curved skin guard is what makes the promise plausible: the maker says it glides over skin and keeps the edge from digging in at the ends of a stroke. It does not make pressure irrelevant. The same page says deep or rough brushing can still irritate the skin and that redness ends the session. The FAQ limits the tool to animals that shed and have an undercoat, and rules out non-shedding breeds and particularly sensitive skin.
Two different mediums on Australian shelves
Amazon AU's unit is the US one: SKU P-92914, barcode 811794929145, Spectrum Brands Pet LLC as manufacturer, and a size band of 25 to 50 pounds, about 11 to 23 kg. The listing's style menu calls this edge "long hair - new model" and also offers a short-hair new model and small and large sizes. Petbarn's medium has a European barcode, 4048422141068, and its own chart: small for dogs of 9 kg or lighter, medium 9 to 23 kg, large 23 to 41 kg, all for fur of 5 cm or longer.
For most dogs the two bands agree. They part company between 9 and 11 kg, where Petbarn calls a dog medium and the US chart would put it on the small. Pick by coat first: long hair means fur of 5 cm or more, and a short-coated dog of the same weight belongs on the short-hair edge. Then pick by weight, and if the dog sits on a boundary, the coat's density is a better tiebreaker than a kilo either way.
Ten to twenty minutes, once or twice a week
The maker's schedule is one or two sessions a week of 10 to 20 minutes, with more frequent sessions in heavy shedding seasons. The coat must be completely dry; right after a wash and a full dry is the best time. Before the first stroke, check the skin for sores, bruises or irritation and see a vet if anything turns up, and work any tangles or mats out with a dematting tool or grooming rake.
Mats are what damage the tool. Pulled through matted fur, the teeth can bend or break, and the dog feels it. Aftercare is short: wash the edge in warm water with mild soap when dander builds up, dry it completely, then press the FURejector button and pull back to lock the Edge Guard over the teeth, which is why the tool needs no cap. Mid-session, the same button pushes collected hair off the teeth so the stroke keeps working.
Check who is selling it, not just who ships it
FURminator's anti-counterfeit page names marketplace sites, Amazon among them, as places where poorly made imitations turn up, and says genuine tools are available at most pet specialty retailers. Its main test is the SOLD BY line, because the business that ships an order is not always the one selling it. On 5 November the anchored Amazon AU offer passed that test, with Amazon AU as both seller and shipper, but the listing also showed two other new offers.
Petbarn, a pet specialty retailer, is the other low-risk route, at A$70 for the medium with store pickup. Buying from either seller puts a faulty tool under Australian Consumer Law with an Australian business, which matters because FURminator publishes no Australian warranty and no Australian reseller list. A marketplace offer from an unfamiliar third party gives up both of those protections to save a few dollars.
Who should skip it
FURminator's own exclusions write most of the list: non-shedding breeds and dogs with particularly sensitive skin should not be brushed with it, a dog with sores or a skin condition needs a vet first, and a matted coat goes to a dematter or a groomer before an undercoat edge goes near it. Weight cuts the rest. Under about 9 kg the small edge fits, and over 23 kg the large one does.
The up-to-90-percent figure is the brand's claim for regular use, and regular means the weekly routine above. An owner who will not spend 20 minutes a week on the coat is outside the conditions the claim is written on, and hair already on the couch is a lint roller's job, not this tool's.
