Overview
If your dog has dandruff but is otherwise well, the first things to check are grooming, washing habits, dryness in the home, and whether there are any signs of irritated skin underneath the flakes. In many cases it’s something simple, but there can be several possible causes, so it’s worth keeping an eye on the bigger picture rather than just the flakes themselves.
Things To Check
1. Check whether the dandruff is new or has been building up over time, and whether it seems worse after grooming, bathing or exercise.
2. Look closely for redness, scabs, broken skin, greasy patches, thinning coat, swelling or areas that seem sore or itchy.
3. Check how often your dog is being bathed, and whether a very frequent wash routine or harsh shampoo might be leaving the skin dry.
4. Run your hands through the coat to see if the flakes are just on the surface or if the coat also feels dull, brittle or oily.
5. Think about the home environment, especially central heating, dry air, recent changes in bedding, or colder weather that may make skin drier.
6. Check whether your dog is otherwise normal in themselves, with a good appetite, normal energy and no signs of discomfort.
7. Review any recent changes in food, treats, supplements, grooming products or parasite control, as these can sometimes be linked with coat changes.
Common Causes
The most common cause is simple dry skin, often linked to weather, indoor heating, or a coat that needs more regular grooming.
Over-bathing, using the wrong shampoo, or not rinsing thoroughly can also leave the skin flaky.
Some dogs get dandruff alongside mild skin sensitivity, mild allergies, or a coat condition that needs better routine care.
Less commonly, dandruff can be part of an underlying skin problem, hormone issue, or parasite concern, especially if there are other signs as well.
What To Do
Start with gentle, regular brushing if your dog tolerates it, as this can help lift loose flakes and spread natural skin oils through the coat.
Keep bathing sensible rather than frequent, and use a dog-friendly shampoo if you do wash them. Make sure the coat is rinsed thoroughly and dried properly afterwards.
If the air indoors is very dry, try to keep your dog’s resting area comfortable and avoid over-heating rooms where they sleep.
Keep a short note of when the dandruff appears, where it shows up, and whether anything else changes, such as scratching, licking or redness.
If the flakes are mild and your dog is bright, eating well and not itchy, you can often monitor things for a short period while keeping up a sensible grooming routine.
When To Contact A Vet
Speak to your vet if the dandruff is persistent, getting worse, or comes with itching, hair loss, redness, odour, scabs, pain or changes in your dog’s behaviour or appetite. It’s also sensible to get advice if the skin looks sore or if home care doesn’t seem to make any difference.
