Why is my dog scratching with flaky skin?

Overview
If your dog is scratching and their skin looks flaky, it’s often linked to dry skin, coat build-up, allergies, irritation or an underlying skin condition such as seborrhoea. The flakes themselves don’t point to one single cause, so it’s worth checking for other signs rather than assuming it’s just dandruff.
Some dogs just need better coat care or a gentler wash routine, while others may have something more ongoing going on. A careful look at the skin, coat and any changes in scratching habits can help you decide what to do next.
Things To Check
1. Check whether the scratching is mild and occasional, or frequent enough to disturb sleep, exercise or settling down.
2. Look closely for redness, scabs, sores, broken skin, hair loss, greasy patches or a strong smell.
3. Feel for hot, sore or thickened skin, especially around the ears, back, belly, armpits and base of the tail.
4. Think about whether anything has changed recently, such as shampoo, bedding, diet, grooming routine or time outdoors.
5. Check for parasites, even if you don’t spot them straight away, especially if the scratching seems to have started suddenly.
6. Notice whether the flakes are dry and fine, or mixed with oil, crusting or discharge.
7. See if your dog seems otherwise well, or if there are signs like lethargy, ear irritation or licking paws more than usual.
Common Causes
Dry skin is a common reason for flaking, especially after too much washing, harsh shampoo, winter heating or low humidity.
Allergies can also cause itching, with flaky skin sometimes showing up alongside rubbing, licking, ear irritation or skin redness.
Build-up of natural skin oils and dead skin, which can happen with seborrhoea, may lead to flakes, greasiness, odour or a patchy coat.
Parasites such as fleas or mites can make dogs scratch a lot, even when the signs are subtle at first.
Less commonly, infections or other skin conditions may be involved, especially if the skin looks inflamed, sore or keeps coming back.
What To Do
Start by keeping a simple record of where the flakes appear, how often your dog scratches and whether anything seems to trigger it. That makes it easier to spot a pattern.
Use a gentle grooming routine and avoid over-washing, as too much bathing can sometimes make dry skin worse. Brush carefully to lift loose flakes and check the coat at the same time.
Keep bedding clean and make sure your dog’s environment isn’t unusually dusty or dry. If you’ve changed food, shampoo or grooming products recently, consider whether that lines up with the problem.
If your dog is licking, rubbing or scratching so much that skin is being damaged, it’s sensible to get veterinary advice rather than waiting for it to settle on its own.
Products That May Help
A gentle grooming and cleansing routine can be useful when you’re trying to manage flaky skin, coat build-up or skin odour at home.
