The best dog undercoat rake for many large, long-haired dogs is the FURminator Large Long Hair Tool because its curved stainless-steel edge, Skin Guard and fur-eject button make regular de-shedding more controlled. The Maxpower Planet Blue Grooming Rake is the stronger choice when a dense coat also needs gentle work through tangles, while Poodoodle suits owners buying specifically for poodle, doodle and other long-haired coats.
How we chose the best dog undercoat rakes
An undercoat rake is not a universal brush. It is intended to reach loose hair beneath the visible topcoat, which is why it can be useful for double-coated dogs during seasonal shedding. It can also cause breakage, pulling or skin discomfort when used too often, pressed too hard, or used on a coat that is already matted. A good purchase starts with your dog's coat, not with the most aggressive-looking teeth.
We compared the three products here by their stated purpose, working edge, control features and the coat types their listings target. The FURminator is a dedicated long-hair de-shedding tool for dogs over 50 pounds. Maxpower Planet combines a double-sided dematting and de-shedding rake in an extra-wide head. Poodoodle is a two-in-one rake marketed for poodles, doodles and other long-haired pets. Those are meaningful differences: one makes routine loose-hair removal easier, while the other two give an owner separate sides for tangles and shedding.
Before buying, part the coat with your fingers. If you can see compacted knots close to the skin, do not expect an undercoat rake to solve them safely. A professional groomer may need to assess the coat first. If the coat is clean, dry and merely releasing lots of soft undercoat, choose a tool with a head width and handle you can control. Short sessions are more sensible than trying to empty an entire coat in one sitting.

Best dog undercoat rakes: the three picks
FURminator Large Long Hair Tool
The FURminator Large Long Hair Tool is the most straightforward choice for a large dog over 50 pounds whose long coat sheds loose undercoat but is not packed with mats. Its listing specifies a stainless-steel deShedding edge for long hair, a curved edge intended to follow the body, and a Skin Guard with rounded corners. Those features matter because a long, broad grooming session is only useful if the head remains easy to guide over ribs, shoulders and haunches. The FURejector button is another practical advantage: collected hair can be released without repeatedly picking it from the edge. Choose it for a retriever, shepherd-type or similar large dog when you want a dedicated weekly shedding tool with a comfortable ergonomic handle. Its limitation is equally important: this is not a cutting comb for knots, and a sharp de-shedding edge can remove more coat than intended if used with pressure or on a dirty, tangled coat.
Pros
- Curved stainless-steel edge follows broad body contours
- FURejector button clears gathered hair without touching the edge
- Specified for long-haired dogs over 50 pounds
Cons
- Not designed to cut through compacted mats
- Requires light, infrequent strokes to avoid overworking the coat
Maxpower Planet Blue Grooming Rake
Maxpower Planet's blue rake is the better fit when loose undercoat comes with small, reachable tangles rather than a smooth coat that simply sheds. The Amazon listing identifies it as an extra-wide, double-sided comb for long-haired dogs and cats, with separate dematting and de-shedding functions. That split lets an owner use the coarser working side only where a small tangle needs attention, then change sides for a lighter pass through the undercoat. The wide head can make a dense body coat quicker to cover, and the rounded-teeth design is intended to be kinder to skin than exposed cutting edges. Choose it for a sturdy adult dog with a dense, medium-to-long coat when you can work slowly and keep the skin taut around a snag. The tradeoff is that a wide two-sided rake is less nimble around ears, legs and sensitive areas, and it must never be dragged through tight mats that resist a gentle stroke.
Pros
- Double-sided head separates dematting work from de-shedding passes
- Extra-wide comb covers dense body coats efficiently
- Rounded teeth help make careful grooming less scratchy
Cons
- Wide head is awkward around legs, ears and narrow joints
- A caught tangle must be worked gently instead of pulled through
Poodoodle 2-in-1 Undercoat Rake
The Poodoodle 2-in-1 Undercoat Rake is the focused option for owners of poodles, doodles and other long-haired dogs who want one hand tool for both loose hair and light dematting. Its Amazon listing specifically calls it a professional grooming brush that combines a dematting and shedding comb, and it explicitly names poodle, doodle and long-haired pets as its intended use. That stated coat focus makes more sense than treating every shedding tool as interchangeable: curly or long mixed coats often need small sections checked for tangles before loose hair is removed. The two-in-one format can reduce the number of tools needed for a careful home routine. Choose it if you already section and comb your dog's coat regularly and want a rake that supports that routine. The limitation is that it is not a shortcut for neglected coat care. Dense, felted areas need professional attention, and owners should use only the side that matches the task instead of repeatedly combing every area.
Pros
- Listing targets poodle, doodle and other long-haired pets
- Two-in-one dematting and shedding comb supports section-by-section care
- Useful when one grooming routine needs two distinct tasks
Cons
- Does not replace a professional assessment of felted coat sections
- Requires owners to switch techniques rather than rake every area repeatedly
Choosing the right rake for your dog
Start with coat length, density and the dog's size. The FURminator is most logical if your dog matches its large, long-hair specification and you need a controlled tool for loose undercoat. Pick Maxpower Planet if the coat is dense and you need a double-sided rake for small tangles plus shedding. Poodoodle is the more targeted selection for a long, curly or doodle-style maintenance routine.
No tool should turn grooming into a battle. Work in a calm space, offer breaks, and inspect the skin as you go. Dogs with redness, sores, fleas, severe mats or obvious discomfort should not be groomed over the problem. Routine brushing with an appropriate pin brush or comb between rake sessions is often the better way to prevent a coat from reaching that stage.
FAQ
Can I use an undercoat rake on every dog?
No. Undercoat rakes are most relevant for dogs that release a substantial undercoat, especially double-coated or dense long-haired dogs. Fine, single coats and very short coats may need a softer brush instead. Check the product's size and hair-length guidance, then use a light hand. If you are unsure about your dog's coat type, a groomer can recommend a safer tool.
Should I use an undercoat rake on mats?
Only on loose, superficial tangles that separate with gentle work. Do not force teeth through a dense mat near the skin, because pulling can hurt the dog and cut or break coat. Use your fingers to hold the hair above a small tangle, stop if it catches, and seek a professional groomer for tight, widespread or felted mats.
How often should I de-shed a long-haired dog?
Frequency depends on coat, season and the tool's instructions. The FURminator listing recommends weekly use, while a dog with a healthy, well-maintained coat may need only brief sessions. Watch the coat and skin rather than following a rigid schedule. If you see irritation, thinning or resistance, pause grooming and reassess your technique or tool.
