Overview
Dry skin and dandruff in dogs can be caused by several common things, including grooming habits, bathing too often or not enough, dry indoor air, diet issues, parasites, allergies, or an underlying skin problem. In many dogs it’s not serious, but flaky skin is worth keeping an eye on so you can spot any changes early.
Things To Check
1. Check whether the flaking is all over the body or just in one area.
2. Look for redness, soreness, scabs, hair loss, odour, greasy skin, or signs of scratching.
3. Think about whether anything has changed recently, such as food, shampoo, bedding, grooming routine, or home heating.
4. Check for fleas, flea dirt, or other signs of parasites, especially around the base of the tail and belly.
5. Notice whether the skin seems worse after bathing, brushing, or time outdoors.
6. Pay attention to your dog’s general comfort, appetite, and behaviour, as skin irritation can sometimes make dogs restless.
7. If the coat looks dull, brittle, or hard to manage, consider whether grooming has become less regular or the dog is shedding heavily.
Common Causes
One of the most common causes is simple dryness from the environment, especially during colder months or when indoor heating is on. Over-bathing, harsh shampoos, or not rinsing well enough can also leave the skin flaky.
Allergies are another common reason. These may be linked to food, pollen, house dust, or something in the dog’s environment, and they often come with itching or redness as well as dandruff.
Parasites such as fleas can cause irritation and flaky skin, even if you don’t see many of them. Some dogs also develop dandruff because of skin infections, poor coat condition, or an underlying health issue that affects the skin and coat.
In some cases, diet or poor nutrient balance can contribute to a dull coat and dry skin. Less commonly, hormonal or other medical conditions can be involved, especially if the skin change is persistent or getting worse.
What To Do
Start by noting when the flaking appears and whether anything seems to trigger it. This can help you spot patterns and decide whether it’s improving or spreading.
Use a gentle grooming routine and avoid over-washing. If you do bathe your dog, make sure the shampoo is suitable for dogs and that the coat is rinsed thoroughly.
Keep an eye on the home environment too. Dry air, dusty bedding, and strong cleaning products can sometimes make skin feel worse, so small changes to the dog’s routine or sleeping area may help.
Make sure parasite control is up to date and check the coat regularly for fleas or irritation. If your dog has a balanced diet but the skin still looks poor, it’s sensible to discuss it with your vet, especially if the problem keeps coming back.
