Overview
If your dog keeps scratching at night, it often means something is irritating the skin, coat or ears. Common reasons include parasites, allergies, dry skin, contact irritation or a reaction to grooming products. The pattern can be helpful, but it doesn’t point to one single cause on its own.
Things To Check
1. Notice whether the scratching is worse after evening walks, bedtime, grooming or coming in from outside.
2. Look closely for redness, scabs, dandruff, bald patches, broken skin, swelling or any discharge.
3. Check the ears, paws, belly, armpits and base of the tail, as these areas often show irritation first.
4. Think about any recent changes to shampoo, bedding, laundry detergent, treats, food or cleaning products.
5. Part the coat and look for fleas, flea dirt or signs of other biting insects, even if you don’t see live fleas.
6. Note whether your dog is also licking, chewing, rubbing the face or shaking the head, as that can suggest a broader irritation issue.
7. Check whether the room is warm, dry or dusty at night, as that can sometimes make skin feel more uncomfortable.
Common Causes
Fleas are one of the most common reasons dogs scratch more at night, especially if the skin is reactive or the irritation is building up over time.
Allergies are another frequent cause. These may be linked to food, pollen, grass, house dust or something your dog has contacted recently.
Dry skin or an irritated coat can also make dogs itch more once they’ve settled down and are no longer distracted by daytime activity.
Sometimes the issue is localised to the ears, paws or belly, which can happen with yeast, minor skin irritation or other skin sensitivity.
Less commonly, skin mites, infections or other skin conditions may be involved, especially if the itching is persistent or the skin looks sore.
What To Do
Start by checking the coat and skin carefully, then keep a brief note of when the scratching happens and what seems to make it worse.
Use only dog-safe grooming and washing routines, and avoid adding new products one at a time if you’re trying to spot a trigger. If you suspect bedding or laundry could be part of the problem, switch to plain, fragrance-free options.
Make sure your dog’s parasite control is up to date if that’s part of their normal routine, and follow the product instructions you’ve been given.
If the skin looks dry, gently managing the coat and keeping the sleeping area clean and comfortable may help reduce everyday irritation.
If the scratching is continuing, spreading, or affecting sleep, arrange a vet check so the cause can be assessed properly.
When To Contact A Vet
Speak to your vet if the scratching is ongoing for more than a few days, your dog has broken skin, sores, hair loss, a strong smell, ear discharge, head shaking, or seems generally uncomfortable. It’s also sensible to get advice sooner if the itching is suddenly severe or your dog is losing sleep.
