Overview
If you find lice on your dog, it’s worth taking it seriously, but there’s no need to panic. Lice usually cause itching, coat changes and irritation, and your dog may need treatment from a vet. It’s also sensible to check whether what you’ve seen is actually lice, because fleas, dandruff and other skin problems can look similar.
Things To Check
1. Look closely at the coat, especially around the neck, ears, shoulders and rump, for tiny moving insects or pale eggs attached to the hair.
2. Check whether your dog is scratching, rubbing, biting at the skin or looking restless more than usual.
3. Part the coat and look for redness, scabs, broken skin or areas where the hair looks thin or uneven.
4. Check other pets in the home for similar signs, since lice can sometimes affect more than one animal.
5. Think about recent contact with other dogs, grooming visits, kennels or shared bedding.
6. Make a note of how long you’ve noticed the problem and whether it seems to be getting worse.
7. Check bedding, collars, brushes and resting areas for anything that looks dirty, itchy or in need of a wash.
Common Causes
Actual lice are one possible cause, especially if you can see tiny insects or eggs in the coat. Fleas are another common cause of itching and can be mistaken for lice at a glance. Skin irritation from allergies, dry skin or another parasite can also make a dog scratch and look uncomfortable. In some cases, a matted coat or poor coat condition can make the skin look worse and harder to assess properly.
What To Do
Keep your dog away from direct contact with other pets until you’ve had proper advice. If you can, use a fine-toothed comb to look through the coat and collect anything you can show your vet. Wash bedding, blankets and grooming tools, and vacuum the places your dog usually rests. Try not to use random shop products without guidance, as the wrong product may not be suitable for your dog. Your vet can confirm whether it is lice and advise on the most appropriate treatment and follow-up care.
When To Contact A Vet
If you think your dog has lice, contact your vet for confirmation and treatment advice. It’s especially important to do this if your dog has intense itching, sore skin, hair loss, scabs, or if other pets in the home are also affected.
