A Shih Tzu’s double coat is its crowning glory — and its single biggest grooming liability. Without daily attention, silky top hair and soft undercoat fuse into painful mats that pull at sensitive skin and force drastic shave-downs. The right brush does more than remove loose fur; it reaches the undercoat before tangles set, distributes natural oils, and keeps your dog comfortable rather than resentful of grooming time.
I’m Mohammad Maruf — the founder and writer behind WellFizz. I’ve spent hundreds of hours analyzing grooming tool specifications for double-coated toy breeds, cross-referencing pin density, tip coating, and bristle angle against real owner feedback to separate genuinely effective designs from shelf-warmers.
After evaluating dozens of models against the specific needs of a Shih Tzu’s coat, I’ve narrowed the field to the five brushes that actually perform. Whether you need a gentle daily slicker, a detangling rake, or a complete kit, this guide covers the best dog brush for shih tzu options available today.
How To Choose The Best Dog Brush For Shih Tzu
A Shih Tzu’s coat is unique — it’s a double coat with a silky outer layer and a dense, soft undercoat that mats quickly if not addressed daily. Choosing the wrong brush can cause breakage, skin irritation, or simply fail to remove the undercoat before it tangles. Here’s what to look for.
Pin Length and Tip Coating
Pins shorter than ¾ inch cannot reach the undercoat of a full-coated Shih Tzu. Look for brushes with pins at least ¾ inch long that reach deep enough to lift loose undercoat hair. Coated tips (plastic or nylon balls on each pin) prevent scratching the dog’s sensitive skin — bare metal pins can cause micro-abrasions, especially on the belly and inner legs where the coat is thinnest.
Bristle Firmness vs. Coat Sensitivity
Shih Tzus have fine, silky hair that breaks more easily than wiry or coarse coats. A medium-firm slicker brush removes tangles without snapping strands, while a soft slicker works best for puppies or dogs with particularly thin coats. Firm brushes are ideal for areas where mats are already forming, but using them on dry, tangle-free coat can cause unnecessary wear.
Ergonomics and Grip
Daily grooming sessions can last 10–15 minutes. A brush with a contoured, non-slip handle reduces hand fatigue. The shape of the head also matters — a slightly curved or tapered head reaches the Shih Tzu’s face, ears, and tail more easily than a perfectly flat, wide head.

In‑Depth Reviews
1. Ryan’s Pet Supplies Paw Brothers Flat Slicker Brush
The Paw Brothers Flat Slicker Brush strikes the most difficult balance in Shih Tzu grooming — it is firm enough to remove undercoat before mats form yet gentle enough that dogs tolerate daily use. The stainless steel pins are coated at the tips, which prevents the scratching and pinching that bare-metal slickers cause on fine-skinned breeds. The flat head gives maximum coverage per stroke, which is critical when you are brushing a full double coat every day.
Professional groomers in the customer feedback specifically highlight this brush for its ability to work through small tangles without pulling. At 3.5 inches across the brush face, it covers a useful amount of coat without being so wide that it skips the Shih Tzu’s legs and tail. The oblong shape allows you to angle the brush into the curve of the neck and behind the ears — the exact spots where Shih Tzus mat first.
Some users note that the brush is larger than expected, which can be awkward on puppies or very small adults under eight pounds. For standard-size Shih Tzus in the nine- to sixteen-pound range, the head size is ideal. The coated pins hold up well over months of daily use without bending or losing their tips.
Why it’s great
- Coated pin tips protect sensitive Shih Tzu skin
- Flat head design removes undercoat efficiently across large areas
- Sturdy build from a brand established since 1959
- Works well on small to medium Shih Tzus without pulling
Good to know
- May feel too large for puppies or dogs under 8 pounds
- Not self-cleaning — hair removal requires manual picking
2. Jelly Pet Universal Slicker Brush
The Jelly Pet Universal Slicker Brush is built specifically for double-coated breeds like the Shih Tzu, with pins that extend more than ¾ inch into the coat to lift dead undercoat before it becomes a mat. The angled pins grip loose hair more effectively than straight bristles — each stroke pulls shedding fur out rather than pushing it deeper. The manufacturer explicitly lists Shih Tzu among the compatible breeds, which is a green flag that the pin spacing and firmness were calibrated for this coat type.
The plastic pins are firmer than the coated wire found on many slickers, giving you more torque when working through tangles without the risk of scratching. The head is contoured, which helps maintain contact with the dog’s body when brushing the rounded ribcage and shoulders. The plastic body is waterproof, making it suitable for use during bath time when wet hair mats most aggressively.
A small number of owners report that the brush does not pull as much loose undercoat as they expected on very dense coats. This may be because the pins, while long, are spaced slightly wider apart than some competitive models, allowing finer undercoat hair to slip between them. On the other hand, this wider spacing means the brush is less likely to snag and pull, making it a strong choice for Shih Tzus who are nervous about grooming.
Why it’s great
- Pins over ¾ inch reach deep into the double undercoat
- Angled design grabs loose hair without aggressive pulling
- Waterproof body works well during wet grooming sessions
- Lightweight and easy to maneuver for extended brushing
Good to know
- Pin spacing may miss very fine undercoat on some coats
- Firm pins require careful pressure to avoid discomfort on thin coat
3. Hertzko Self Cleaning Slicker Brush
The Hertzko Self Cleaning Slicker Brush offers a practical solution for owners who brush daily but hate the tedious work of picking hair out of bristles. The push-button mechanism retracts the fine wire pins into the brush head, allowing you to wipe the collected fur off in one motion. For a Shih Tzu owner brushing every day, this feature alone can save minutes per session and keep the brush performing like new rather than clogged with undercoat.
The bristles themselves are fine and closely spaced, which makes the brush effective at capturing the delicate undercoat hair that wider-spaced pins miss. The angled bristles create a massaging sensation that many dogs enjoy — several owners report their dogs come running when they see the brush. The handle has a soft grip that reduces hand strain during longer grooming sessions, which is important when you are brushing a full Shih Tzu coat from head to tail.
The trade-off is that the fine wire bristles are less effective at breaking up established mats. If your Shih Tzu has gone a few days without brushing and small tangles have formed, the Hertzko may glide over them rather than working through them. The plastic build also feels lighter and less premium than metal-backed brushes, though the mechanism itself holds up well with regular use.
Why it’s great
- One-button retraction makes hair removal fast and easy
- Fine wire bristles capture delicate undercoat effectively
- Comfortable grip reduces hand fatigue during daily grooming
- Gentle massaging action helps dogs tolerate brushing
Good to know
- Fine bristles struggle with established mats and tangles
- Plastic body feels less durable than metal-backed alternatives
4. 3PCS Pet Grooming Rake & Metal Comb & Flea Comb
This three-piece kit addresses the reality that a single brush cannot handle every stage of Shih Tzu coat maintenance. The double-sided undercoat rake uses nine teeth on one side for breaking up stubborn mats and seventeen teeth on the other side for thinning and removing loose hair. The metal comb has a wide-tooth side for smoothing and a dense side for removing loose hair from sensitive areas like the face, legs, and tail — exactly where slicker brushes are too large to work effectively.
The rake is the standout piece. Its stainless steel teeth are blunt-tipped, which reduces the risk of scratching the skin when working through mats near the armpits and groin. Multiple customer reviews note that the rake removes mats in two strokes where other tools require repeated passes. The flea comb is a bonus for owners who want to check for debris or dandruff during grooming, though it is not essential for everyday coat maintenance.
Some owners report that the racket-style handle of the rake can feel a bit bulky in smaller hands. The rubber grip helps, but the overall shape is better suited to owners with average to large hands. Additionally, the metal comb tends to accumulate loose hair between its teeth quickly, requiring frequent wiping during use.
Why it’s great
- Double-sided rake tackles both stubborn mats and loose hair
- Fine-tooth comb reaches face, ears, and tail where slickers cannot
- Blunt rake tips reduce skin irritation risk
- Comprehensive kit covers all grooming stages for one price
Good to know
- Rake handle may feel bulky for owners with small hands
- Comb teeth catch hair quickly and need frequent cleaning
5. 3PCS Self Cleaning Slicker Brush & Grooming Rake & Flea Comb
This kit combines the two most useful grooming tools — a self-cleaning slicker brush and a double-sided undercoat rake — into a single purchase. The slicker brush uses the same push-button retraction design as the Hertzko, with fine wire bristles that capture shedding undercoat hair efficiently. The rake mirrors the nine-tooth and seventeen-tooth configuration of the previous kit, giving you both dematting and deshedding capabilities in one set. The flea comb included rounds out the kit for owners who want a single source for all grooming needs.
Customer feedback emphasizes the quality of the materials. The rubber handle on the rake provides a secure grip even when wet, and the stainless steel teeth on both the rake and comb resist rust with regular use. The self-cleaning mechanism on the slicker brush works smoothly, with a firm press of the button retracting the bristles completely for easy hair removal. For Shih Tzu owners who want both a daily brush and a mat-breaking tool without buying separately, this kit delivers more value than buying pieces individually.
A minor concern raised by some buyers is the presence of a light greasy residue on the tools upon first opening, which appears to be manufacturing lubricant. A quick wash with warm soapy water resolves the issue, but it is worth inspecting the tools before first use. Additionally, the slicker brush bristles are fine and may not stand up to aggressive brushing on very dense mats — the rake is the better tool for that job.
Why it’s great
- Self-cleaning slicker brush for fast daily grooming sessions
- Double-sided rake handles mats that the slicker cannot
- Rubber grips provide secure hold even during wet brushing
- Complete set covers daily brushing and dematting needs
Good to know
- Tools may arrive with light manufacturing residue — wash before use
- Slicker brush bristles are best for maintenance, not tough mats
