Overview
Contact a vet if the matting is tight against the skin, looks painful, is linked with redness, sores, swelling or smell, or if your dog is very uncomfortable when you try to brush it. A vet is also a good idea if the coat is so badly tangled that you can't safely remove it at home. In many cases, matting is caused by coat type, shedding, moisture, dirt, rubbing or not grooming often enough, but the skin underneath may need checking too.
Things To Check
1. See whether the matting is just on the surface or packed down close to the skin.
2. Look for redness, damp patches, scabs, broken skin, discharge, swelling or a bad smell under the mat.
3. Check if your dog seems sore, flinches, hides, scratches, licks or resists being touched in that area.
4. Think about whether the coat gets wet, muddy or tangled after walks, swimming or time in long grass.
5. Check if the matting is around friction areas such as behind the ears, under the collar, in the armpits, around the tail or between the legs.
6. Look at how quickly the coat is tangling and whether your usual grooming routine has changed recently.
7. Check for signs your dog isn't coping well with handling, such as trembling, snapping, tail tucking or trying to get away.
Common Causes
The most common cause is simple coat tangling that has built up over time, especially in longer or curly coats. Moisture, mud and debris can make knots tighten quickly. Mats often start in friction areas where the coat rubs against collars, harnesses or bedding. Less commonly, skin discomfort, excess shedding, a skin condition or reduced grooming because your dog feels unwell may make matting more likely.
What To Do
Start by checking how severe the matting is and whether the skin underneath looks normal. If the coat is only lightly tangled, gentle regular brushing may help, but stop if your dog seems sore. If the mat is tight or close to the skin, don't pull at it, as that can hurt and may damage the skin. Keep the coat as clean and dry as you can, especially after walks or wet weather, and build grooming into your routine before tangles have a chance to set in. If the matting keeps coming back, it may help to review the coat length, brushing frequency and any areas where friction or moisture build up.
When To Contact A Vet
Speak to a vet if the matting is pulling on the skin, there is redness, swelling, discharge, scabbing or a smell, or your dog seems painful or distressed. Also get advice if the coat is so matted that you can't remove it safely, because the skin underneath may need treatment or the coat may need to be clipped professionally.
