Overview
If your dog is scratching nonstop after flea bites, it usually means the skin is still irritated, there may still be fleas around, or your dog may be reacting quite strongly to the bites. Check the skin and the coat first, then focus on keeping your dog comfortable and monitoring for any worsening signs.
It’s also worth remembering that a lot of different skin issues can look similar at first, so you may not be able to tell the exact cause at home.
Things To Check
1. Look through the coat with a flea comb, especially around the base of the tail, belly, neck and inner thighs.
2. Check for black specks that turn reddish-brown on damp cotton wool, which can suggest flea dirt.
3. Look closely for redness, broken skin, scabs, sore patches or areas that feel warm.
4. Notice whether the scratching is constant or comes and goes after certain activities, such as walks, grooming or time outside.
5. See if your dog is licking, chewing or rubbing the same area as well as scratching.
6. Check whether any other pets in the home are scratching too.
7. Make a note of whether the itching seems worse at night or after lying on certain bedding.
Common Causes
The most common reason is that flea bites have left the skin irritated, especially if your dog is sensitive to flea saliva.
Ongoing flea activity is another common cause. Even a small number of fleas can keep the itch going, particularly if they’re hiding in the coat, bedding or home environment.
Sometimes the scratching is made worse by the dog’s own skin becoming sore from repeated rubbing and licking.
Less commonly, the itching may be linked to another skin problem happening at the same time, such as another allergy or a skin infection.
What To Do
Start by checking whether fleas or flea dirt are still present, and make a note of where and when the scratching is happening.
Wash or change your dog’s bedding and vacuum any areas they rest on regularly, including sofas and carpets if your dog uses them.
Try to stop the skin getting more irritated. If your dog is chewing or scratching hard, keep an eye on the area so it doesn’t become raw or infected.
Keep your dog’s routine calm and simple for a day or two so you can see whether the itch settles or keeps building.
If there are other pets in the home, check them too, because fleas can affect the whole household.
If the scratching is continuing, worsening, or the skin is starting to look sore, it’s sensible to speak to your vet for advice.
