Overview
If your dog is shedding more than usual and has dandruff, it’s often linked to dry skin, seasonal coat changes, grooming habits, or something in the environment. It can also happen alongside skin irritation, parasites or underlying health issues, so it’s worth checking the coat closely rather than assuming it’s just normal shedding.
In many cases, you can narrow it down with a few simple checks at home and then use sensible grooming and care steps to support your dog’s coat.
Things To Check
1. Check whether the shedding is seasonal or has started suddenly.
2. Look closely for redness, scabs, broken skin, greasy patches or bald areas.
3. Run your hands through the coat to see if the dandruff is fine and dry, or if the skin feels oily, sore or flaky.
4. Check for scratching, licking, rubbing, head shaking or signs that your dog seems uncomfortable.
5. Make sure you’re using a grooming routine that suits your dog’s coat type and how often they’re brushed or bathed.
6. Check for fleas or other signs of parasites, especially around the tail base, belly and neck.
7. Think about any recent changes in diet, bedding, shampoo, household cleaners or where your dog sleeps.
8. Notice whether your dog’s drinking, appetite, weight or energy have changed as well.
Common Causes
Seasonal coat changes are one of the most common reasons for heavier shedding, especially in dogs that blow their coat at certain times of year.
Dry skin can cause visible flakes and more loose hair, particularly if the air indoors is dry, your dog is bathed too often, or the wrong grooming products are being used.
Build-up of dead hair and skin can also make dandruff look worse if the coat isn’t being brushed regularly enough for that dog’s coat type.
Fleas, mites and other skin irritants can lead to shedding, dandruff and itching, even when the skin problem is still fairly mild.
Less commonly, allergies, hormonal changes, infections or other health conditions may affect the coat and skin together.
What To Do
Start with a steady grooming routine that suits your dog’s coat, using a brush that removes loose hair without irritating the skin.
Keep an eye on how often you’re bathing your dog, because over-washing can leave the coat dry and flaky in some dogs.
Try to keep bedding clean and comfortable, and note whether the dandruff is worse after time in certain rooms, outdoors or on particular surfaces.
If your dog seems itchy or uncomfortable, monitor the pattern for a few days and write down what seems to make it better or worse.
If the shedding is persistent, the flakes are heavy, or there are signs of skin irritation, it’s sensible to get a vet’s advice so the cause can be checked properly.
When To Contact A Vet
Contact your vet if the dandruff and shedding are getting worse, your dog is very itchy or uncomfortable, or you notice bald patches, sores, redness, odour or skin thickening. It’s also a good idea to ask for advice if there are other changes such as weight loss, low energy, drinking more than usual or a poor appetite.
Products That May Help
If your dog’s coat and skin are looking a bit dry or flaky, a gentle grooming and care routine can sometimes help support day-to-day coat maintenance.
