Key takeaways
- Pin length: Look for extra-long pins around 25 to 30 mm so they penetrate the guard coat and reach the undercoat rather than skimming the surface.
- Pin flexibility: Slightly flexed, angled wire pins glide over skin instead of digging in, which matters on a Shepherd’s thinner belly and flank areas.
- Self-cleaning mechanism: A retractable-pin button that ejects trapped hair with one press saves several minutes per session when the fur comes out in clumps.
- Handle ergonomics: A cushioned, non-slip grip prevents wrist fatigue during the 15 to 20 minute sessions a full-coat brush-out demands.
- Head size: A wider head covers a large dog faster, but keep a smaller head on hand for the legs, ears, and behind the joints where mats hide.
What's inside
A German Shepherd is a double-coated breed that blows its undercoat twice a year, and during those weeks a single dog can shed enough loose fluff to fill a grocery bag. A quality slicker brush is the single most effective tool for pulling that dead undercoat out before it ends up on your sofa, because its fine, angled wire pins reach down past the guard hairs to the dense insulating layer underneath.
Not every slicker is built for a coat this thick, though. Short-pinned brushes made for a Yorkie will skate over a Shepherd’s dense fur without grabbing anything, and pins that are too stiff can scratch skin. Below we break down what actually matters for a working double coat and review five brushes that hold up to twice-weekly deshedding on a 70-pound dog.

The Best Picks Reviewed
Paw Brothers Professional Grade Extra Long Slicker Brush
This is the workhorse of the group. The extra-long pins are the real draw for Shepherds because they reach the dense undercoat that standard slickers miss entirely, and the ergonomic handle keeps your wrist neutral through a long session. It has no self-cleaning button, so you clear the pad by hand, but the trade-off is a sturdier head that survives daily use on coarse fur.
Chris Christensen Big G Dog Slicker Brush
Designed originally for Poodles and doodles, the Big G’s large head and long, springy pins make short work of a Shepherd’s coat too. It is the premium pick and priced accordingly, but groomers reach for it because the pins flex just enough to fluff and detangle without raking the skin. If you want one brush to last a decade, this is it.
Professional 3PCS Self Cleaning Slicker Brush and Grooming Rake Set
This kit pairs a self-cleaning slicker with a double-sided dematting rake and a flea comb, which covers the full deshedding workflow in one purchase. The retractable pins are genuinely useful during a coat blow when you are emptying the pad every 30 seconds, and the included rake handles the deep undercoat the slicker loosens.
Professional Deshedding Dog Brush Grooming Kit (3-in-1)
Sold as a gift-box set for long-haired breeds, this combines a deshedding edge and a slicker so you can loosen, lift, and finish with one product. It is a strong value choice for a first-time Shepherd owner who wants to try both tool styles before committing to a single premium brush.
Tweezerman Slicker Brush for Large Pets
The coated bristles are the standout feature here, adding a touch of protection so the pins are gentler on skin during aggressive deshedding. The large-pet sizing suits a Shepherd’s frame, and it is a good middle-ground option for owners who found bare-wire slickers too sharp for their dog’s comfort.
Frequently Asked Questions
How often should I brush my German Shepherd’s undercoat?
During normal weeks, two brief slicker sessions a week keep loose hair under control. When the coat blows in spring and fall, brush every day or every other day for two to three weeks to move the dead undercoat out quickly.
Will a slicker brush hurt my dog’s skin?
Not if you use a light touch and let the pins do the work. Hold the brush at a shallow angle, use short strokes, and never bear down. Angled or coated pins reduce the risk of the scratchy irritation groomers call slicker burn.
Is a slicker brush enough, or do I need an undercoat rake too?
For a heavy coat blow, pairing the two works best. The rake pulls the deep, loosened undercoat while the slicker lifts and finishes the outer coat. Several picks above bundle both tools for that reason.
Can I use these brushes on a wet coat?
Brush a dry, fully detangled coat. Wire pins drag on wet fur and can tighten mats instead of removing them. Bathe and blow-dry first, then brush the dry, fluffed coat.
Final Thoughts
For most German Shepherd owners the Paw Brothers extra-long slicker is the practical everyday choice, while the Chris Christensen Big G justifies its price if you want a brush that will outlast several dogs. Whichever you pick, pair short regular sessions with a deeper twice-yearly routine during coat-blow season and you will keep both your dog comfortable and your floors far cleaner.
