Overview
If your dog’s skin is itchy, you should contact a vet if it’s lasting more than a few days, getting worse, making them sore, or affecting their sleep, appetite or behaviour. A bit of scratching can come from several common causes, but ongoing itching usually means something needs proper attention.
Things To Check
1. Notice when the itching happens, such as after walks, grooming, washing, or at certain times of day.
2. Look for red skin, broken skin, scabs, hair loss, swelling, heat, or any discharge.
3. Check your dog’s ears, paws, belly, armpits and base of the tail, as these are common itchy spots.
4. See whether they’ve been licking, chewing, rubbing or scratching the same area repeatedly.
5. Think about possible triggers such as a change in food, bedding, shampoo, grass, pollen or household cleaners.
6. Use a flea comb if you have one and check for fleas or flea dirt, even if you haven’t seen fleas recently.
7. Make a note of any smell, greasy coat, dandruff or flaky skin, as these can help your vet narrow things down.
Common Causes
The most common causes are fleas, environmental allergies, skin irritation from grooming products, and sensitivities to something your dog has touched or been exposed to. Dry skin, a dirty coat or over-washing can also make itching worse.
Less commonly, the problem may be linked to a skin infection, ear issue, mites or another medical condition that needs proper diagnosis.
What To Do
Keep a simple record of when the itching started, where your dog scratches, and whether anything seems to make it better or worse. If you can, reduce obvious triggers by avoiding new shampoos, rinsing off mud or pollen after walks, and keeping bedding clean and dry.
Try not to let your dog keep scratching until the skin is damaged. If they’re making themselves sore, or the itch is continuing despite basic care, it’s sensible to book a vet visit.
When To Contact A Vet
Contact your vet if the itching is persistent, severe, waking your dog up, or causing redness, bleeding, scabs, hair loss or a strong smell. You should also seek advice sooner if your dog is licking or chewing constantly, seems uncomfortable, or the itching starts suddenly and spreads quickly.
It’s especially important to call if you notice ear problems, paw swelling, repeated skin infections, or any change in appetite, energy or behaviour alongside the itching.
Products That May Help
If your dog’s skin is itchy or their coat needs a gentle reset, a good routine for washing and grooming can help support day-to-day skin and coat care.
