What to do when a dog has lice?

How to Treat and Prevent Lice in Dogs

Discovering that your dog has lice can be alarming, but with the right knowledge and care, this issue is manageable. Lice infestations in dogs, while uncommon, can still pose discomfort and health risks. This guide will walk pet owners through everything from symptoms to treatments and prevention strategies.

Understanding Canine Lice

Dog lice are tiny, wingless insects that live in the fur and feed on your dog's blood or skin debris. There are two main types:

• Chewing lice (Trichodectes canis) – Feed on skin debris and secretions.
• Sucking lice (Linognathus setosus) – Feed on the dog’s blood.

These parasites are species-specific, meaning dog lice cannot infest humans or cats, and vice versa.

Signs Your Dog May Have Lice

Lice infestations are often visible to the naked eye, especially in short-haired breeds. Look for these signs:

• Frequent scratching or biting at the skin
• Dry, matted coat
• Irritated or red skin
• Presence of white or yellow lice or eggs (nits)
• Hair loss, especially around the neck, ears, shoulders, and groin

Immediate Steps to Take

1. Isolate the Infected Dog
Keep the affected pet away from other animals until the infestation is under control. 2. Consult With a Veterinarian
A vet can confirm the diagnosis and prescribe the appropriate treatment. 3. Use Medicated Treatments
Options include:

• Prescription spot-on treatments
• Anti-parasitic shampoos containing pyrethrin or permethrin
• Oral medications for moderate to severe cases

Always follow the vet's dosage and frequency instructions for safe and effective treatment.

Comprehensive Cleaning Measures

To prevent re-infestation, it’s crucial to clean your dog’s environment:

• Wash all bedding and soft toys in hot water
• Vacuum carpets, furniture, and car interiors thoroughly
• Disinfect grooming tools and collars

Preventing Lice in Dogs

Even though lice are spread mainly through direct animal contact, prevention remains key:

• Avoid letting your dog interact with stray or infested animals
• Regularly groom and inspect your dog's coat
• Maintain a clean living space
• Use monthly parasite preventatives as recommended by your veterinarian

When to Seek Further Help

If symptoms persist beyond 2–3 weeks or if your dog shows signs of secondary infections (e.g., increased redness, pus, fever), consult your vet. Some dogs, particularly puppies or immunocompromised animals, can suffer more severe effects from lice infestations.
