Professional advice recommended
Book a non-urgent veterinary appointment.
This needs a professional
Professional guidanceExtensive or tight mats must be clipped out with electric pet clippers (never scissors — you can cut the skin). Larger or tight-to-the-skin mats warrant a groomer or vet, sometimes under sedation.
Brushing by coat type
FactDouble coats: slicker brush then a comb, at least weekly — don't shave by default.
Watch for
- Severe matting can strangle a limb (circumferential mats cut off blood flow) and irritate or infect the skin — don't let it get that far.

Why this answer
Minor tangles can be brushed or combed out at home, but extensive or tight-to-the-skin mats must be clipped out with electric pet clippers — never scissors, which cut skin — and large or tight mats warrant a groomer or vet, sometimes under sedation. Severe matting is a welfare issue: mats can strangle a limb and cause skin infections. Regular brushing to the coat type (daily for long/curly, weekly for double coats) prevents it.
When this doesn’t apply
- Mats tight against the skin or around a limb are a vet visit, not a DIY job.
- There's no exact size threshold — severity is judged by how tight and extensive the matting is.
What changes the answer
- How matted the coat is (a few tangles vs. pelted).
- Coat type sets the brushing frequency that prevents mats.
- Whether mats are loose or tight against the skin.

Common questions
Can matted fur be brushed out or does it need shaving?
Small tangles brush out; extensive or tight mats must be clipped (never scissored). Large or skin-tight mats need a groomer or vet, sometimes with sedation.
Was the groomer right to shave my matted dog?
Often yes — a severely matted coat can't be safely brushed out and mats can strangle skin or limbs. The issue is usually communication, not the shave itself. Prevent it with regular coat-appropriate brushing.
