Overview
Large flakes of skin in dogs are often linked to dry skin, seborrhoea, grooming buildup or an underlying skin irritation. It’s usually something that can be checked calmly at home first, but there can be more than one cause.
If the skin also looks red, greasy, smelly or sore, that can point towards a skin problem rather than simple dryness.
Things To Check
1. Check whether the flakes are dry and powdery, or greasy and stuck to the coat.
2. Look closely for redness, scabs, broken skin, swelling, discharge or a strong smell.
3. Notice whether your dog is scratching, licking, rubbing or seeming uncomfortable.
4. Think about any recent bathing, new grooming products, brushing changes or time spent outdoors in mud, dust or dry weather.
5. Part the coat in a few places to see if the skin underneath also looks flaky, oily or inflamed.
6. Check whether the problem is localised to one area or spread across the body.
7. Make a note of any change in appetite, energy or coat condition, as this can help spot a wider issue.
Common Causes
The most common reason is simple dry skin, especially in colder weather, after frequent washing, or if the coat is not being groomed through properly.
Another common cause is seborrhoea, where the skin makes too much scale or oil. This can leave the coat flaky, greasy or both.
Skin irritation from allergies, parasites or environmental triggers can also cause flaking, especially if your dog is itchy as well.
Less commonly, flakes can be linked to infection, hormonal changes or an underlying skin condition that needs veterinary assessment.
What To Do
Start by keeping a close eye on the pattern of the flakes and whether your dog seems itchy, sore or smelly as well.
Stick to a sensible grooming routine and avoid over-washing, as that can sometimes make dryness worse.
If the coat is very dusty or dirty, gentle brushing can help lift loose scale and let you see whether the skin underneath is improving or getting worse.
It can also help to note any changes in diet, environment, bedding or washing products, since these can sometimes play a part.
If the flakes are persistent, worsening, or coming with redness, odour or discomfort, it’s worth getting veterinary advice.
