Dog Lice: Prevention & Natural Treament

Many dog owners’ first thoughts when they hear the term "dog lice" are… Oh no! First my toddler, now I have to worry about the dog getting infested?!

Let's get to the good news right up front, that way the rest won't seem all that bad. Dog lice can not be transferred to humans nor can human lice be transferred to dogs.

So...


What are Dog Lice?

Dog lice are not commonly found on dogs in the United States. Dogs that live in a clean environment and receive regular grooming have a slim chance of contracting them, while poorly nourished dogs are more likely to attract and retain them.

They are slightly smaller than fleas and are a lighter color, more like beige or tan. And fortunately they cannot jump from host to host like human lice can. They are actually very slow moving, almost motionless on the skin of the dog.

There are two main types of lice that can attach themselves to your dog. (Don’t fear the technical terms for these varmints…they are slightly scary!)

  1. Sucking (linognathus piliferus setosus) - feed on the blood of the dog and in turn can be more irritating to the dog.

The human kind like our hair because we keep it nice and clean whereas the dog kind prefer the dirt and oil on the hair of our dogs. Lice on dogs are quite easy to spot on the hair and skin, especially when you are looking for them.

The fleas attach their eggs with a type of glue substance to the hair of the dog. The eggs are the most stubborn and resistant to treatments.

How Can Your Dog Come Into Contact with Dog Lice?

As previously stated, dog lice are quite rare in the U.S., and the chance of a young, healthy dog contracting them is very small.

But... dogs do still come in contact with these varmints and it is possible for one dog to spread them to another dog. Since dog fleas can’t jump, there has to be physical contact between the dogs in order to pass them on.

What are the most common places for dogs to contract lice? It could happen anywhere, but the most likely spots are the obvious…dog parks, walking trails, grooming instruments, and other dogs' bedding, just to name a few.

What is the Life Cycle of Dog Lice?

The female lice can lay up to 100 eggs (also called nits), which are attached to the hair follicle with a glue like substance. The "glue" makes the eggs much more difficult to get rid of.

The life cycle takes just about 21 days to complete, so if they go untreated, your dog could be home to thousands of lice in a very short amount of time.

Can Dog Lice Harm Your Dog?

Dog lice are annoying, stubborn and sometimes itchy, but they are not harmful to your dog.

If your dog has contracted the kind that sucks blood, then there will be more irritation, itching and biting of the skin. All that you can do is to try to get rid of them as soon as you can! Read on...

What are the Most Effective Natural Treatments for Dog Lice?

There are a few very effective treatments for dogs with lice. Fortunately, lice are the easiest parasite to treat because they are not active in our environment like fleas and ticks.

Here are a few recommended natural treatments:

  1. Bathe your dog daily with a good natural dog shampoo such as Tropiclean Oatmeal Shampoo. Leave the lather on the hair for ten minutes.
  2. After bathing your dog, try applying a natural lemon rinse, also effective for the treatment of fleas and ticks. This lemon rinse will help to slowly kill of the remaining eggs. See our Dog Flea Medicine page to learn how to make and use an effective natural lemon rinse.
  3. Removing the eggs attached to the hair follicles is the most difficult part of eliminating them. Try rubbing mayonnaise into the hair of your dog and massaging with your fingertips. This may help to loosen the eggs and then you can follow up with a nice firm shampooing to wash the eggs down the drain.

If you have tried all of these natural treatments and you still have a problem, ask your veterinarian or one of our veterinarians for additional recommendations and possibly a stronger, more potent potion.
