Dog Brushes Explained: Which Tool for Which Coat
A slicker on a smooth coat does nothing, and a deshedding blade on a doodle does damage. Here's which brush matches which coat, and which ones to skip.

Walk into any pet shop and there are thirty brushes on the wall, most of them promising to solve shedding. The reason people end up with a drawer full of them is that brushes aren’t better or worse than each other. They do different jobs, on different coats, and a tool that transforms one dog does nothing at all on another.
This is a guide to matching the tool to the coat. It’s based on how each type works and what groomers and veterinary sources say they’re for, not on a bench test of particular brands; picking a specific model is the easy part once you know which category you actually need.
Key Takeaways
- Coat type decides the tool. A brush that’s perfect for a Golden Retriever is useless on a Whippet.
- The undercoat rake does the real work on heavy shedders; the slicker finishes.
- Bladed deshedding tools cut hair. Keep them off curly, wool and single coats entirely.
- Never brush a wet mat, and never cut one out with scissors.
Work Out Your Dog’s Coat First
Everything follows from this, and it isn’t always obvious.
Short and smooth — Labradors, Beagles, Boxers, Whippets, French Bulldogs. Hair lies flat, sheds steadily, doesn’t mat.
Double coat — German Shepherds, Golden Retrievers, Huskies, Corgis. A soft dense undercoat under a coarser topcoat. These are the heavy seasonal shedders, and our guide to why dogs shed covers what’s normal.
Curly or wool — Poodles, doodles, Bichons. Hair grows continuously instead of shedding much, which is why they’re often called hypoallergenic. It mats readily and needs professional clipping.
Silky long — Cocker Spaniels, Yorkshire Terriers, Setters. Long fine hair, feathering on the legs and ears, mats behind the ears and in the armpits.
Wiry — Terriers, Schnauzers. Coarse, harsh topcoat, traditionally hand-stripped rather than clipped.
The Tools, and What Each One Is For
Slicker Brush
Fine, bent wire pins on a flat or curved head. The general-purpose brush for anything with length to it: double coats, silky coats, curly coats. It lifts loose hair, works out small tangles and finishes the coat.
Use it on: double, curly, wool, silky. Not much use on: short smooth coats, where it mostly scratches skin. The mistake: pressing hard. Slicker pins are fine wire and enough pressure abrades skin, which is what groomers call brush burn. The brush should sit on the coat, not be driven into it. Look for pins with rounded tips.
Undercoat Rake
A single or double row of long, widely spaced rounded teeth, designed to reach through the topcoat and pull loose undercoat out.
Use it on: double coats. This is the tool that actually reduces the hair in your house. Never on: curly, wool or single coats — nothing to rake, and it drags on skin. The mistake: carrying on past the point of usefulness. Rake until it stops bringing out loose fluff and then stop. Repeated raking of a coat that has nothing left to give thins it.
Bristle Brush
Natural or synthetic bristles set close together. Doesn’t remove much loose hair; distributes skin oils and puts a shine on the coat.
Use it on: short smooth coats as a finisher, and long silky coats after detangling. Honest assessment: it’s a finishing tool. If you bought one hoping to fix shedding, that was never its job.
Rubber Curry or Grooming Mitt
A flexible rubber pad or glove with short nubs. Loose hair sticks to it, and most dogs find the sensation pleasant.
Use it on: short smooth coats. This is the right tool for a Labrador or a Beagle, and it’s cheap. Bonus: it doubles as a bath brush, which pairs with our guide to how often to bathe your dog.
Deshedding Tool with a Blade
The category that includes the well-known branded ones. A fine-toothed metal edge that pulls undercoat out and, unavoidably, cuts some hair as it goes.
Use it on: heavy double coats, sparingly, during a coat blow. Keep it away from: curly, wool, silky and single coats. On a doodle it shreds the coat. On a thin-coated dog it reaches skin. The mistake: using it weekly as a normal brush. It removes coat faster than the dog replaces it.
Metal Comb
A plain comb with fine teeth at one end, wider at the other. Unglamorous and the most useful diagnostic tool you own.
Use it on: everything with length. After brushing, run the comb through. If it passes freely, you’re done. If it snags, the mat is still there and the brush was skating over the top of it.
This is the single most useful habit in this article. Most owners who think their dog is well brushed are brushing the surface of a coat that’s matting underneath.
Dematting Rake
Hooked blades that cut through a mat to break it up.
Use it on: a mat that a comb and fingers can’t work out. Carefully: the blades cut, and skin can be pulled into a tight mat closer than you’d think. For anything large, tight or close to the skin, a groomer or vet is the right call, not a tool.
Matching Tool to Coat
| Coat | Main tool | Finisher | Avoid |
|---|---|---|---|
| Short smooth | Rubber curry | Bristle brush | Slicker, rake |
| Double | Undercoat rake | Slicker, comb | Nothing, but go gently |
| Curly / wool | Slicker | Metal comb | Any bladed deshedder |
| Silky long | Slicker | Metal comb, bristle | Bladed deshedder |
| Wiry | Slicker, stripping knife | Metal comb | Bladed deshedder |
The Rules That Matter More Than the Brush
Never brush a wet mat. Water tightens it. Dry the dog first.
Never cut a mat out with scissors. Skin lifts into a tight mat and this is a common way owners cut their dog. If it must come off, clippers under the mat, or a groomer.
Work in small sections, holding the hair at the base so you’re pulling against your own hand rather than the dog’s skin.
Check the trouble spots, which the topcoat hides: behind the ears, under the collar, armpits, between the back legs, under the tail.
Short sessions, ending well. Two calm minutes beats ten that end in a fight. A dog who tolerates handling is also a dog whose ears you can check and whose nails you can trim without a struggle.
A dog who suddenly hates being brushed may be sore. In an older dog, new objection to being handled around the back end is worth mentioning to your vet, because arthritis is easy to miss.
Frequently Asked Questions
What is the best brush for a dog that sheds a lot? For a double-coated shedder like a German Shepherd or Golden Retriever, an undercoat rake does most of the work, with a slicker brush for finishing. The undercoat is what sheds heavily, and a rake reaches it where a surface brush only tidies the topcoat. Use the rake gently and stop when it stops producing loose fur.
Can I use a deshedding blade on any dog? No. Bladed deshedding tools cut hair as well as pull it, and on a single-coated or curly-coated dog such as a Poodle, doodle or Bichon they damage the coat with no benefit. They are for heavy double coats only, used sparingly, and never on a dog with thin or sensitive skin.
How often should I brush my dog? Curly and wool coats need brushing several times a week or they mat, regardless of season. Double coats want two or three times a week, and daily during a seasonal coat blow. Short smooth coats are fine with a weekly rubber curry. Frequency is set by coat type, not by how dirty the dog looks.
Why does my dog hate being brushed? Most often because a tool is being used on the wrong coat, a slicker is being pressed too hard, or an existing mat is being pulled. Brush burn from over-worked slicker bristles is a real and painful thing. Sudden new dislike of brushing in an older dog can also be pain, and arthritis is worth ruling out with a vet.
The takeaway
Two tools cover most dogs: the right main brush for the coat, and a plain metal comb to check your work. Everything else on that shop wall is either a finisher or a specialist. If you own a heavy shedder, spend on a good undercoat rake and use it gently. If you own a doodle, spend on a slicker and a comb and keep every bladed deshedder away from the coat entirely.
