Why is my dog so itchy and scratching nonstop?

Overview
If your dog is scratching nonstop, mange is one possible cause, but it’s not the only one. Fleas, other parasites, skin irritation, allergies and infection can all make a dog very itchy, so the main job is to look for patterns and visible changes rather than trying to guess the cause straight away.
Things To Check
1. Check whether the itching is worse after walks, time outdoors, grooming or at night.
2. Look closely for bald patches, red skin, scabs, dandruff or areas your dog keeps rubbing or chewing.
3. Part the coat and check for fleas, flea dirt, mites or any signs of other insects on the skin.
4. Notice whether the itching seems localised to one area, such as the ears, belly, chest, paws or face, or whether it’s more general.
5. Check for any smell, moist skin, discharge or thickened skin, which can suggest irritation or infection alongside the itching.
6. Think about any recent changes, such as new shampoo, bedding, food, grooming products or contact with other animals.
7. Watch for changes in behaviour such as restlessness, poor sleep, reduced appetite or discomfort when touched.
Common Causes
Fleas and flea allergy are very common causes of intense itching, even if you do not spot many fleas at first.
Mange, caused by mites, can also lead to heavy scratching, hair loss, scabby skin and a dog that seems very uncomfortable.
Other parasites or biting insects can cause short-term irritation, especially if the itching started after time outdoors.
Skin allergies, dry skin and contact irritation from something your dog has touched can all look similar at home.
In some dogs, scratching nonstop leads to a secondary skin infection, which can make the itching worse and the skin look sore or greasy.
What To Do
Keep a simple note of when the itching happens, where your dog is scratching and what the skin looks like. That can be very helpful if you need advice later.
Try to avoid bathing or using new products on sore skin unless you know they’re suitable, as over-washing can sometimes make irritation worse.
Wash bedding regularly, vacuum soft furnishings and check other pets too, especially if fleas or mites could be involved.
If your dog is scratching hard enough to break the skin, try to prevent more trauma by limiting rubbing, licking and chewing as much as you reasonably can.
If the itching is persistent, spreading or clearly making your dog miserable, a vet can help work out whether parasites, mange, allergy or infection is the more likely cause.
Products That May Help
If your dog’s skin is sore or itchy, simple grooming and coat-care routines can help you keep the skin clean, spot changes sooner and support day-to-day comfort.
