Let me tell you about the worst forty dollars I ever spent: a bargain slicker brush from the pet store that bent its pins within a month, scratched Winston's skin, and ultimately ended up in the donation pile. I bought it because I didn't know any better. You shouldn't have to make the same mistake.
After three years and more trial-and-error than I'd like to admit, I've settled on a specific set of tools that actually work on double-coated dogs. Some are investment pieces that will last years. Others are affordable workhorses. All of them earn their keep during coat blow season.


The Core Arsenal: Tools You Can't Skip
These are the non-negotiables. Every double-coat owner needs these tools, and buying quality versions upfront will save you money and frustration in the long run.
The Slicker Brush
A slicker brush has fine wire pins on a flat or curved pad and is your everyday go-to for maintaining the coat between deep grooming sessions. The cheap ones have pins that bend, rust, or scratch. The good ones last decades.


I use the Chris Christensen Big G Slicker Brush for Winston and the slightly smaller Original version for Maggie. At around $50-60 each, they're not cheap. But the pins are stainless steel, the cushion is firm enough to reach the undercoat without being harsh, and I've been using my Big G for nearly three years with zero issues. The groomers at my local shop use the same brand.
The Undercoat Rake
This is where coat blow gets conquered. An undercoat rake has long, rounded teeth that reach through the guard coat to grab the loose undercoat beneath. Without one, you're only grooming the surface while the real problem builds underneath.
The Paw Brothers Double Row Undercoat Rake is my desert-island grooming tool. The double row of teeth covers more area per stroke, the rounded tips don't scratch skin, and the teeth are long enough to actually reach Winston's dense undercoat. I bought mine for under $15, and it's performed better than rakes costing three times as much.
Some people swear by the single-row rakes for precision work around the legs and face. I keep a Safari Undercoat Rake (single row) for those areas, but the double-row handles probably 90% of my undercoat removal.
The Greyhound Comb
A metal comb with both fine and coarse teeth, the greyhound comb is your finishing tool and your mat detector. Run it through after brushing, and if it catches, you've missed something. If it glides through, you're done.
I use a 7.5-inch greyhound comb from Chris Christensen with half fine teeth and half coarse teeth. The coarse side handles the body coat; the fine side checks the delicate areas behind the ears and in the armpits where mats love to hide. Around $25 and worth every penny.
| Tool | Brand/Model | Price Range | Primary Use |
|---|---|---|---|
| Slicker Brush | Chris Christensen Big G | $50-60 | Daily maintenance, topcoat care |
| Undercoat Rake | Paw Brothers Double Row | $12-18 | Undercoat removal, coat blow |
| Greyhound Comb | Chris Christensen 7.5" | $20-28 | Finishing, mat detection |
| Dematting Tool | Safari Dematting Comb | $8-12 | Breaking up mats safely |
The Upgrade Tools: For Serious Grooming
These tools aren't strictly necessary, but they make grooming significantly more effective. If you're managing two double-coated dogs like me, or if your dog has particularly dense fur, these are worth the investment.
The High-Velocity Dryer
This single tool transformed my grooming routine more than anything else I've purchased. A high-velocity dryer blows room-temperature air at high speed, literally blasting loose undercoat out of the coat. No heat damage, no effort required beyond pointing the nozzle.
I have the K-9 III Dog Grooming Dryer, which runs around $400. Yes, that's a lot. But consider that each professional blow-out session costs $40-60 in my area. By doing it myself, the dryer paid for itself within the first year. Our dedicated high-velocity dryer buying guide covers budget-friendly home options starting around $230. During coat blow, I use it after every bath, and the amount of fur that comes out is honestly alarming. Handfuls. Bags worth.
If the K-9 III is out of budget, the Flying Pig High Velocity Dryer is a solid alternative at around $200. Slightly less power, but still far more effective than trying to brush out a wet double coat by hand.
The Line Brushing Station
Once I got serious about grooming, I set up a dedicated space with a grooming table and arm. My table is a Flying Pig 36-inch adjustable height model with a grooming arm to keep Winston and Maggie from wandering off mid-session. Total setup cost around $180, and it's made grooming so much easier on my back.
You don't need this to start. I groomed on the floor for my first year. But if you're committed to maintaining double coats for the long haul, being able to stand upright and have your dog at a comfortable height makes the whole process more sustainable.
The Mat Splitter
Even with regular grooming, mats happen. Behind the ears after a rainy walk. In the armpit area during coat blow. Between the toes if you're not vigilant. A mat splitter lets you break up mats safely without cutting out chunks of coat.
The Hertzko Mat Remover is what I keep in my grooming kit. The curved blades slice through mats while the protective edges prevent skin cuts. It's saved me multiple trips to the groomer for mat removal and costs under $15.
Tools I've Abandoned
Not everything marketed for double coats actually works. Here's what I bought, tried, and eventually set aside.
The FURminator (Controversial Take)
I know the FURminator is wildly popular, and I owned one for about six months. The deshedding blade does remove an impressive amount of undercoat. The problem is how it does it. The blade is essentially cutting the undercoat rather than pulling out loose fur, and with extended use, I noticed it was also cutting guard hairs and leaving Winston's coat looking thinner and less healthy.
Some groomers use the FURminator carefully and effectively. But for home use, I found it too easy to overdo it and damage the coat. The undercoat rake achieves similar results without the risk of cutting healthy hair.
Rubber Curry Brushes
Great for short-coated dogs. Useless for double coats. The rubber teeth don't penetrate past the guard hairs to where the actual shedding is happening. I tried the Kong ZoomGroom on Winston, and all it did was smooth down his topcoat while the undercoat continued building up underneath.
Shedding Blades
These loop-shaped metal tools with serrated edges are way too harsh for double coats. They're designed for horses and extremely short-coated dogs. On Winston's coat, the shedding blade just pulled and snagged. Another donation pile resident.
Maintaining Your Tools
Good grooming tools are an investment. Taking care of them extends their life and keeps them working effectively.
After every session, I clean the hair out of my brushes and rakes. Built-up fur reduces their effectiveness and can harbor bacteria. A quick wipe with a dry cloth handles most cleanup.
Monthly, I wash my slicker brush and combs with warm soapy water, rinse thoroughly, and let them air dry completely before storing. Metal tools can rust if put away damp.
The high-velocity dryer gets its filter cleaned after every use. The owner's manual has specific instructions, but basically: clean filter equals happy motor equals dryer that lasts for years instead of dying during peak coat blow when you need it most.
