Collie Grooming Guide

The Collie Coat

What kind of coat does a Collie (Rough Collie) have?

Last updated October 8, 2026

The Rough Collie has one of the most dramatic coats among herding breeds: a dense, flat undercoat topped by a harsh, straight outer coat that stands off the body, with a particularly profuse mane and frill around the neck and chest. The smooth Collie variety has the same double coat in a short, dense form and requires far less maintenance. This guide focuses primarily on the Rough Collie coat, which is the more common variety and the most grooming-intensive.

Grooming Tools You'll Need

• Pin brush — primary tool for the outer coat; prevents damage to the harsh outer guard hairs
  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.
• Undercoat rake — 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.
• Wide-tooth steel comb — for checking the mane, frill, and feathering for tangles
• Slicker brush — for finishing and removing fine debris
  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.
• Dematting tool or mat splitter — for working out tangles before they develop into mats
• Dog-safe shampoo and conditioner formulated for double 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 dryer (strongly recommended for this coat volume)

Grooming Reality: Daily or Professional

A Rough Collie in full coat maintained at home requires daily brushing — not weekly, not "a few times a week." Owners who don't brush daily typically choose professional grooming every 6–8 weeks to keep the coat manageable. Both approaches work; the key is committing to one of them and maintaining it consistently.

Regular Routine

How often should you groom a Collie (Rough Collie)?

Daily Brushing

• Work through the coat section by section with a pin brush, starting at the base of the coat and working outward — this lifts the coat off the undercoat rather than sliding over the surface
• The mane and frill are the highest priority areas — these mat fastest and most severely. Brush them first at every session
• Check behind the ears, in the armpits, and along the hindquarters — secondary mat-risk areas
• Follow with an undercoat rake through the body coat to remove loose undercoat
• Finish with a steel comb through the mane and frill to confirm the coat is tangle-free to the skin

Professional Grooming Alternative

Many Rough Collie owners use professional groomers every 6–8 weeks. A groomer familiar with the breed will provide a thorough deshedding bath, blow-dry, and light tidying without cutting the coat length. Specify that the coat should not be shaped or clipped — the Rough Collie coat should not be trimmed, only maintained.

Monthly

• Full bath every 6–8 weeks. Conditioner is essential — the coat tangles significantly when wet and dried without conditioning
• Blow-dry completely. The dense undercoat holds moisture and can take hours to dry naturally — damp skin under the coat is a hot spot risk
• Trim nails monthly

Coat Blow Season (Twice Per Year)

Collies blow their undercoat twice a year in spectacular volume. Daily brushing during this 3–4 week period is required. A deshedding bath session removes most of the releasing undercoat efficiently and shortens the blow duration.

Mane and Drug Sensitivity

The Mane Is the Work — and Know the MDR1 Status

The Rough Collie's most distinctive feature — the profuse mane and frill — is also the highest-maintenance part of the coat. Without daily attention, the mane mats from the inside out. Mats that reach the skin require professional dematting (expensive and uncomfortable for the dog) or shaving (which destroys the signature appearance). Daily mane brushing is the foundation of Collie coat care.

Mane Technique

• Brush the mane daily — even a 2-minute daily session is more effective than a 20-minute weekly session
• Work the mane in sections from the outside in, lifting and brushing rather than pulling through from the surface
• Apply a light detangling spray to the dry mane before brushing — it significantly reduces hair breakage and eases comb-through
• A steel comb used through the fully brushed mane confirms you've reached the skin and there are no hidden developing mats

MDR1 Drug Sensitivity

Rough Collies are affected by the MDR1/ABCB1 mutation at a high rate — up to 70% of Rough Collies may carry at least one mutant copy. This mutation makes the blood-brain barrier permeable to certain medications including some dewormers (ivermectin, milbemycin) and certain anesthetics. Responsible breeders DNA-test both parents; ask for documentation. Have your vet test your dog if breeder documentation is unavailable. The results must be in your dog's medical record and should be carried as a medication alert card.
