Long-Haired Dog Grooming: Brushing, Mats & Coat Care

Long-haired dogs can look beautiful, soft, and elegant, but their coats need consistent care.

A long coat can hide tangles underneath the surface. It can collect dirt, moisture, loose hair, burrs, and debris. It can also mat around high-friction areas like the ears, armpits, belly, tail, legs, and paws.

Long-haired dog grooming is not just about keeping the coat pretty. It is about comfort, skin health, and preventing mats before they become painful.

This guide explains how long-haired coats work, which tools may help, how often to brush, what areas to check, and when professional grooming may be needed.

Quick Answer: How Do You Groom a Long-Haired Dog?

Brush the coat in small sections, then follow with a metal comb to check your work. Focus on high-risk areas such as behind the ears, under the collar, armpits, belly, tail, legs, and paws. Brush before bathing, dry the coat fully, and call a professional groomer if mats are tight, painful, damp, smelly, or close to the skin.

The goal is not to pull through every tangle.

The goal is to keep the coat clean, comfortable, and manageable.

What Counts as a Long-Haired Dog Coat?

A long-haired dog coat is any coat that grows long enough to tangle, drag, feather, form furnishings, or require regular brushing to stay manageable.

Long-haired dogs may have:

silky coats
flowing coats
drop coats
feathered coats
double coats
dense undercoats
long mixed coats
long curly or wavy coats
long hair around the ears, legs, tail, chest, or belly

Examples may include breeds and mixes such as Shih Tzus, Maltese, Yorkshire Terriers, Havanese, Lhasa Apsos, Cocker Spaniels, Collies, Shetland Sheepdogs, Afghan Hounds, Old English Sheepdogs, long-haired Dachshunds, and many mixed-breed dogs.

Breed can help you understand the starting point, but the dog’s actual coat condition matters more.

A long coat that is brushed daily may be easy to manage. The same coat, ignored for two weeks, may become difficult.

Why Long-Haired Dogs Mat Easily

Long hair moves, rubs, and tangles.

When your dog walks, plays, sleeps, scratches, wears a collar, or rolls outside, the coat shifts against itself. Loose hair can get trapped in the longer coat instead of falling away. Moisture can make the hair clump together. Over time, small tangles can tighten into mats.

Long-haired dogs often mat because of:

missed brushing
brushing only the surface
not using a comb after brushing
long hair around moving body parts
collars, harnesses, sweaters, or coats rubbing the hair
moisture from baths, rain, snow, or swimming
air-drying a tangled coat
dirt, burrs, seeds, or debris in the coat
coat changes as puppies mature
skin sensitivity or pain that makes brushing harder
grooming appointments spaced too far apart

The ASPCA notes that regular brushing and combing can help remove dirt, spread natural oils, prevent tangles, and keep the skin cleaner. ASPCA Dog Grooming Tips

Best Tools for Long-Haired Dog Grooming

Long-haired dogs usually need more than one grooming tool.

The best tool setup depends on coat type, length, thickness, sensitivity, and whether the coat is already tangled.

Slicker brush

A slicker brush can help separate hair, remove loose coat, and work through small tangles.

Use gentle pressure. Do not scrape the skin or repeatedly brush one spot until it turns red.

A slicker brush may be useful for:

long fluffy coats
feathered areas
coats that tangle easily
removing loose trapped hair
preparing the coat before a comb check

Pin brush

A pin brush can be helpful for longer flowing coats, silky coats, and dogs with feathering.

It may be gentler than a slicker brush for some dogs, but it may not remove hidden tangles as well on dense coats.

Metal grooming comb

A metal comb is one of the most important tools for long-haired dog grooming.

A brush can make the coat look smooth on the outside while tangles remain underneath. The comb helps you check whether the coat is actually clear.

Use the wider side first. Use the finer side only when the coat is already moving freely.

Detangling spray

A dog-safe detangling or conditioning spray may help with small loose tangles.

It should not be used to force through tight mats. If the mat is close to the skin, painful, damp, smelly, or difficult to separate, stop and contact a groomer.

Undercoat rake

Some long-haired dogs also have a thick undercoat. An undercoat rake may help remove loose undercoat when used properly.

Use care. The wrong tool used too aggressively can irritate the skin or damage the coat.

Grooming dryer

A dryer can help separate the coat after bathing, especially on thick or long coats.

Avoid high heat. Watch the dog’s comfort closely. Stop if the dog becomes overheated, frightened, or distressed.

The AKC notes that longhaired dogs often need pin brushes, while slicker brushes can be used to remove mats and dead hair. AKC: How to Groom a Dog at Home

How to Brush a Long-Haired Dog

The safest brushing method is slow and section-by-section.

Do not start by dragging a brush from head to tail. That often smooths the surface and misses the problem areas underneath.

Try this method:

Place your dog on a safe, non-slip surface.
Choose a small section of coat.
Use your fingers to separate the hair.
Hold the coat near the skin to reduce pulling.
Brush gently from the ends of the hair toward the roots.
Use short, light strokes.
Check the same section with a metal comb.
Move to the next section only when the comb passes through gently.

If the comb catches, do not yank. Stop and inspect the area.

A calm brushing session is better than a long battle.

High-Risk Matting Areas on Long-Haired Dogs

Some areas mat faster than others because they move, rub, or hold moisture.

Check these areas often:

behind the ears
under the collar
under harness straps
armpits
chest
belly
inner legs
groin
tail base
tail feathering
feet and toes
sanitary area
beard or mouth area
anywhere clothing rubs

Harness areas need special attention. A dog can look brushed on the back but still have mats hiding under the straps.

Feet and toes also matter. Long hair between the toes can collect dirt, moisture, and debris.

Should You Brush Before Bathing?

Yes, in most cases.

Bathing a tangled long-haired dog can make mats worse. Water can tighten knots, and shampoo may not reach the skin properly when the coat is packed.

Before bathing:

check the coat with your hands
brush in small sections
comb-check the coat
remove loose tangles
do not bathe over tight mats
ask a groomer for help if the coat is already difficult

After bathing:

rinse thoroughly
blot gently with a towel
avoid rough rubbing
dry the coat fully
brush and comb-check once the coat is ready
pay extra attention to ears, belly, legs, paws, and tail

VCA Animal Hospitals notes that matted fur can block airflow to the skin and retain water after rain or swimming, creating conditions where hot spots may develop. VCA: Hot Spots in Dogs

How Often Should You Brush a Long-Haired Dog?

There is no single schedule for every dog.

A long silky coat may need daily attention. A long double coat may need regular brushing plus seasonal undercoat care. A long coat kept in a shorter trim may be easier to maintain.

A practical starting point:

Daily

Check high-risk areas with your fingers.

Several times per week

Brush in small sections and follow with a comb.

Before every bath

Brush and comb-check before water touches the coat.

After rain, snow, swimming, or outdoor play

Dry the coat and check for clumps, burrs, or tangles.

Every grooming appointment

Ask the groomer which areas are matting fastest.

If mats keep returning, the coat length, brushing routine, drying method, or appointment schedule may need to change.

Long Coat vs Shorter Trim

A long coat can be beautiful, but it has to be realistic.

A shorter trim may be better when:

the coat mats between appointments
the dog dislikes brushing
the owner cannot keep up with comb checks
the dog swims often
the coat stays damp
harnesses keep causing mats
the dog is elderly or sensitive
the groomer repeatedly finds hidden tangles

A shorter coat is not giving up. It can be a kinder choice.

The best coat length is the one your dog can comfortably maintain.

When You Should Not Brush Mats Out

Not every mat should be brushed out at home.

Stop and contact a groomer when:

the mat is tight against the skin
the comb cannot enter the coat
the mat feels hard or packed
the dog cries, growls, snaps, freezes, or panics
the area smells bad or feels damp
the skin is red, raw, swollen, bleeding, or painful
several mats are connected
mats are near the ears, armpits, groin, feet, tail, or face

Do not cut under mats with scissors. Skin can be pulled into the mat and may be cut accidentally.

Professional Grooming for Long-Haired Dogs

Many long-haired dogs need regular professional grooming.

A groomer can help with:

bathing
drying
coat trimming
sanitary trims
paw and toe hair
mat removal
undercoat removal
coat shaping
brushing technique
finding hidden problem areas

Ask your groomer:

How often should this dog come in?
Is this coat length realistic?
Which areas are matting first?
What brush and comb should I use?
Should we use a shorter trim?
What should I do after baths or wet weather?
When should I stop brushing and book help?

The Dog Groomer Interview Assistant can help you prepare questions before calling or booking.

Common Long-Haired Dog Grooming Mistakes

Avoid these mistakes:

brushing only the top layer
skipping the comb check
bathing before removing tangles
letting the coat air-dry while tangled
rubbing the coat roughly with a towel
leaving harnesses on too long
using scissors under mats
using harsh brushing pressure
waiting too long between grooming visits
keeping the coat long when it repeatedly mats

Long-haired dog grooming works best when the routine is realistic.

Simple Long-Haired Dog Grooming Routine

Here is a simple routine many owners can follow:

Daily

Check ears, collar area, armpits, belly, tail, legs, and paws.

Several times per week

Brush in small sections and comb-check.

Before bathing

Remove tangles before the coat gets wet.

After bathing

Dry thoroughly and check the coat again.

Monthly or as recommended

Schedule professional grooming based on coat length and condition.

Anytime mats return

Review the haircut, tools, brushing frequency, drying method, and appointment schedule.

Final Thoughts

Long-haired dog grooming takes patience and consistency.

The coat may look smooth on the surface while tangles are forming underneath. That is why brushing and comb-checking matter so much.

Focus on small sections, high-risk matting areas, proper drying, and regular professional grooming when needed.

A long coat is only worth keeping long if the dog can stay comfortable.

The goal is a clean, healthy, manageable coat that supports the dog’s comfort — not a style that becomes painful to maintain.
