Overview
If you suspect lice on your dog, it’s worth calling the vet if the scratching is heavy, the skin looks sore, your dog is losing coat condition, or the problem keeps coming back. Many dogs with lice are itchy and uncomfortable, but similar signs can also happen with other skin and parasite issues, so it’s sensible to check rather than assume.
In mild cases, you can first look closely at the coat and skin, keep notes on what you’re seeing, and arrange advice if things don’t settle quickly.
Things To Check
1. Look for constant scratching, nibbling, rubbing or restlessness, especially after walks, grooming or contact with other animals.
2. Part the coat in good light and check for small moving insects, pale eggs attached to hair, or flakes that don’t brush away easily.
3. Check for red, sore or broken skin, because itching can quickly lead to self-trauma.
4. Notice whether the coat looks dull, patchy or greasy, or whether your dog is shedding more than usual.
5. Think about whether any other pets in the home are scratching too, as close contact can matter.
6. Review recent grooming, boarding, kennelling, rescue history or contact with animals that may have had skin issues.
7. Watch for signs that your dog seems generally unwell, such as tiredness, poor appetite or unusual irritability.
Common Causes
The most common reason owners notice lice is actual lice infestation, which can cause irritation, coat changes and visible eggs or insects in the fur.
Other common possibilities include fleas, mites, allergies, dry skin, dirty coat conditions or general skin irritation from grooming products or the environment.
Less commonly, more widespread skin disease or another underlying health issue can make the coat look poor or make itching seem more severe than expected.
What To Do
Keep your dog comfortable and avoid overhandling any sore areas. Use a fine comb if your dog will tolerate it, and check the coat in bright light so you can note what you’re seeing.
Wash bedding, brush regularly, and keep an eye on any other pets that may have close contact. If the itching is mild, a short period of monitoring may help you see whether it is improving or spreading.
Book a vet appointment if you’re not sure what you’re seeing, if the skin is getting worse, or if more than one pet is affected. Lice can be difficult to distinguish from other parasite problems at home, so a proper check can save time and repeated guesswork.
