Overview
Itchy skin in dogs is usually not an emergency, but it can be if it comes on suddenly, is severe, or is happening alongside swelling, broken skin, bleeding, discharge, pain, or your dog seeming unwell. In many cases it’s caused by something fairly common, such as fleas, allergies, contact irritation or a skin infection, but you can’t tell the cause for certain just by looking.
Things To Check
1. Check whether the itching started suddenly or has been building over days or weeks.
2. Look closely for redness, swelling, scabs, hot areas, hair loss, broken skin or discharge.
3. See if your dog is scratching, licking or chewing one area, or is itchy all over.
4. Check for fleas, flea dirt or signs of bites, especially around the tail base, belly and back legs.
5. Notice whether it began after grooming, a shampoo change, a walk in long grass, a new bedding product or any new food.
6. Watch for ear rubbing, head shaking, paw licking or face rubbing, which can go along with skin irritation.
7. Check if your dog seems dull, sore, restless, off food or uncomfortable when touched.
8. Look at whether the itching is keeping your dog awake or causing repeated self-trauma.
Common Causes
The most common causes are fleas, allergies and simple skin irritation from something your dog has come into contact with. Dry skin, grooming products, environmental triggers and seasonal flare-ups can also make dogs scratch more than usual.
Less commonly, itchy skin can be linked with skin infections, ear problems, mites or other underlying health issues. Sometimes more than one thing is going on at once, which is why ongoing itching can be hard to pin down without a vet check.
What To Do
If the itching is mild and your dog otherwise seems well, keep a note of when it happens, where they scratch and anything that seems to make it worse. This can help you and your vet spot patterns.
Check carefully for fleas and keep up with your usual parasite control if it’s due. If you suspect a product, shampoo or new bedding has irritated the skin, stop using it and keep the area simple and clean.
Try to stop your dog making the skin worse by scratching, licking or chewing. Calm, regular grooming can also help you notice changes early, as long as it doesn’t seem to make the itchiness worse.
When To Contact A Vet
Contact your vet promptly if the itching is severe, sudden, spreading or causing broken skin, bleeding, swelling, discharge or obvious pain. You should also seek advice if your dog seems unwell, the ears are involved, or the scratching is not settling after a short period of sensible home monitoring.
If your dog has facial swelling, trouble breathing, collapse, or a rapidly worsening reaction, seek urgent veterinary help straight away.
