Bernese Mountain Dog Grooming Guide

The Berner Coat

What kind of coat does a Bernese Mountain Dog have?

Last updated October 8, 2026

The Bernese Mountain Dog has a moderately long, slightly wavy or straight double coat: a thick, dense undercoat and a longer outer coat. The tricolor pattern — jet black, rich rust, and white — is the breed's most visually striking feature. Maintaining it requires genuine commitment: without regular brushing, the coat mats quickly, particularly in friction areas.

Grooming Tools You'll Need

• Undercoat rake — primary tool for removing loose undercoat
  One option: Maxpower Planet Undercoat Rake on Amazon. A dual-sided rake: the 9-tooth side works through tangles and the 17-tooth side thins out loose undercoat in dense double coats. Work in the direction of hair growth and ease off over bony areas.
• Slicker brush — for the outer coat and mat detection
  One option: Chris Christensen Big G Slicker Brush on Amazon. The Big G has long, angled pins set in a flexible cushioned pad, built for working through double, long and curly coats. Use light strokes; slicker pins can scratch skin if pressed hard.
• Wide-tooth steel comb — essential for working through mats and checking coat completeness
• Stainless steel pin brush — finishing brush
  One option: Chris Christensen Oval Pin Brush (27 mm) on Amazon. Chris Christensen's Original Series oval pin brush: 27 mm stainless pins without ball tips in a cushioned pad, made for long, silky and double coats. Brush in layers from the skin out; a pin brush is for daily maintenance, not for working out mats.
• Dog-safe shampoo and conditioner formulated for long coats
  One option: Wahl 4-in-1 Lavender Chamomile Dog Shampoo (24 oz) on Amazon. Wahl's 4-in-1 formula cleans and conditions in one step; it's pH balanced and paraben free, with a lavender-chamomile scent. It's scented; choose an unscented formula if your vet has flagged sensitive skin.
• High-velocity pet dryer (highly recommended)
• Detangling spray for mat-prone areas

NEVER Shave a Berner

The double coat regulates body temperature in both directions. Shaving permanently disrupts this system and risks post-clipping alopecia — abnormal, patchy regrowth. In summer heat, provide shade, water, and air conditioning. The coat itself is not the problem.

Regular Routine

How often should you groom a Bernese Mountain Dog?

Mat-Prone Areas — Check These First, Every Session

Before brushing the full body, always check and work through these areas where matting develops first:

• Behind and inside the ears
• Collar and neck area
• Armpits and groin (friction zones)
• Between the rear legs
• Feathering on the back of the legs

Use the wide-tooth comb in these areas. If the comb doesn't pass through freely, work out the tangle before brushing. Never brush over a mat — it tightens the base and makes removal harder.

3–4 Times Per Week (Normal Periods)

• Undercoat rake through the entire body — neck, back, sides, belly, legs, tail
• Slicker brush over the full coat
• Comb through mat-prone areas
• Check ears; clean if needed

Monthly

• Bathe every 6–8 weeks or when dirty. The thick coat requires thorough soaking, complete lathering, and full rinse — partial shampooing leads to residue and coat dullness
• Dry completely with a high-velocity dryer. Incomplete drying in a dense coat like the Berner's creates ideal conditions for hot spots. Air drying alone can take 6+ hours
• Trim nails every 3–4 weeks
• Dental brushing 3–4 times per week — the Berner's deep breeding community emphasizes dental health given the short lifespan

Shedding Season (Spring and Fall)

Daily brushing required during the 3–4 week coat blows. A professional deshedding bath — soak, condition, blow out with high velocity — shortens the duration and removes the bulk of loose undercoat efficiently. Many Berner owners schedule professional grooming sessions timed to the coat blow for this purpose.

Managing Mats

Mat Prevention and Removal

Matting is the primary grooming challenge for Berners. The combination of the long outer coat and dense undercoat creates matting conditions whenever the coat is neglected for more than a week, especially in friction zones.

Prevention

• Never skip the mat-prone areas during regular brushing
• Use a detangling spray before brushing if the coat is dry
• Check under collar and harness regularly — these create constant friction
• After swimming or getting wet, brush the coat before it fully dries to prevent matting as the coat dries in clumps

Removing Existing Mats

• Apply detangling spray and let it work for a few minutes
• Hold the base of the mat against the skin with one hand to prevent pulling skin while working
• Use fingers to separate large mats, then use a mat splitter or dematting comb
• Work from the outer edge inward toward the skin — never pull through a mat from the skin outward
• For tight, dense mats close to the skin: consider clipping them out. A professional groomer may need to remove severe matting before regular brushing can resume

Grooming Costs

Professional grooming for Berners runs $80–$150 per session due to the size and coat. Most Berner owners groom at home between professional sessions and book professionals for full deshedding baths 2–3 times per year. Annual professional grooming costs: $200–$450.
