Many people are familiar with human head lice, but did you know there’s such a thing as dog lice? While it’s not a pleasant topic to think about, dog lice are a reality for many pet owners.
These tiny parasitic insects feed on your dog’s blood and can cause several problems, including skin irritation, hair loss, and anemia. In severe cases, lice infestation can even be fatal. So what do you need to know about dog lice? Keep reading to find out.
What is Dog Lice?
Lice are small, wingless insects that infest the skin of dogs, cats, and other animals. Two main types affect dogs: chewing lice and sucking lice.
Chewing lice feed on skin and hair while sucking lice feed on blood. Both types can cause irritation and itching and lead to hair loss and skin damage.
Lice infestations are more common in dogs that live in crowded or unsanitary conditions. However, any dog can be affected by lice, and infestations can spread quickly from one animal to another.
Adult lice are tiny, six-legged insects measuring about 2 to 3 millimeters. They are dark brown or black and are usually found close to the base of the hair shafts, near the skin.
How Do Dogs Get Lice?
Dogs typically become infested with lice after coming into contact with another infected animal. This can happen when dogs share bedding or grooming tools or play together in close proximity.
Dogs who spend time outside and come into direct contact with other dogs are most susceptible to lice infestations. This is especially true if they brush up or tussle with an unprotected dog, like at a dog park.
In some cases, an infestation can also occur if an infected dog brushes up against furniture or walls where another infested animal has recently been.
Also, finding them on rescue dogs is quite common, particularly when they come from unclean environments. Those working at the rescue centers often have to separate these puppies and treat them for lice before they can be adopted.
What are the Signs of Dog Lice Infestation?
The most common sign of an infestation is intense itching and scratching. If your dog is constantly scratching itself or seems unusually uncomfortable, it may be because of lice.
Other dog lice symptoms of infestation include:
- Thinning hair
- Bald spots
- Reddened skin
- Restlessness
- Dry Coat
- Dark specks in your canine’s fur (these are the lice themselves)
In severe cases, dogs may also develop anemia due to blood loss from constant biting and scratching. If you think your dog may have lice, take it to the vet for confirmation. It’s essential to catch the infestation early so that it doesn’t cause any lasting damage to your dog’s health.
Two Species of Lice That Infest Dogs
If you’re a dog owner, the last thing you want to hear is that your pup has lice. But unfortunately, it’s not uncommon for dogs to get infested with these tiny insects. In fact, two different types can affect dogs. These lice are known as Trichodectes canis (the chewing louse) and Linognathus setosus (the sucking louse). Here’s what you need to know about these pests:
Trichodectes Canis: The Chewing Louse
The most common type on dogs are chewing lice. As its name implies, the chewing louse feeds on skin debris and hair, which it rasps off with its mouthparts. They then chew on the dead skin cells of the dog host.
Chewing lice are tiny (about 2 mm in length), flat, and brown. They are typically found around the base of the dog’s tail and in the area between the toes.
Chewing lice cause intense irritation and may lead to self-trauma, secondary bacterial infections, anemia, and even death in severe infestations. This species is found worldwide and can serve as a vector for the canine tapeworm.
Linognathus Setosus: The Sucking Louse
The sucking louse is similar in size and appearance to the chewing louse but feeds on blood instead of skin and hair. These lice are found primarily on the dog’s back and thighs.
Sucking lice cause irritation and make the dog’s coat look mangy. In severe infestations, they can lead to anemia. They are small creatures that cause wounds that can become infected.
Usually, the diagnosis is made by seeing either the lice themselves or their eggs on an infested pet. In addition, parting the hair of said animal often reveals the presence of these pests.
How to Safely and Effectively Treat Lice in Dogs
Many dog owners face the problem of dealing with these parasites at some point. While they are not dangerous, they are a nuisance and can cause your dog a lot of discomfort. Fortunately, several treatment options are available to get rid of lice on dogs.
Let’s explore some of the most popular methods for getting rid of lice in dogs so you can decide what’s best for your pet.
Topical Treatments
Some dog owners opt to use topical skin treatments to get rid of lice. These treatments usually come in the form of a spray or powder that is applied directly to the affected area.
Topical skin treatments are typically effective at killing lice, but they can be harsh on your dog’s skin and may require multiple applications to achieve long-lasting results.
Flea Treatments
Flea treatments are another popular method for treating lice in dogs. Many flea collars and shampoos contain ingredients that will also eliminate lice; however, flea shampoo needs to include the chemical permethrin to kill lice.
Flea treatments are often more gentle on your dog’s skin than topical skin treatments and only require one application to be effective. However, some flea treatments can be toxic to dogs if misused, so it’s essential to read the label carefully before using any products on your pet.
For best results, use a flea comb to remove dead lice and eggs from your dog’s fur before applying the flea treatment product. Follow the instructions on the product label carefully to avoid over-treating your pet.
Shaving Your Dog
Fur shaving is sometimes used as a last resort for treating lice in dogs. This method involves completely shaving off all of your canine’s fur so that the parasites have nowhere to hide.
While this method is effective, it can be stressful for you and your dog. In addition, your dog may be more susceptible to sunburn and other skin problems after being shaved.
Treatment Duration
The duration of treatment will depend on the method you choose and the severity of your dog’s infestation. Topical treatments usually need to be applied every few days until the lice are gone, while flea collars and shampoos typically only need to be used once. If you opt to shave your canine’s fur, the hair will eventually grow back, and the lice will likely return.
Risk of Treatment
All the methods we’ve mentioned come with some risks that you should be aware of before starting any treatment. For example, topical skin treatments can cause irritation and dryness if used too frequently, while flea treatments can be toxic if not used properly. Shaving your pup’s fur also carries the risk of cuts and infection if not done carefully.
How To Prevent Your Dog From Getting Lice
Fortunately, you can do a few things to prevent your dog from getting lice in the first place. Here are a few tips:
1) Keep your dog clean and well-groomed. A clean coat is less likely to attract lice. Be sure to brush your dog regularly and bathe them as needed using a medicated shampoo designed for dogs.
2) Avoid contact with other dogs who may be infested. If you must be in close proximity to other dogs, try to keep their heads away from yours as much as possible.
3) Check your own head for lice before coming into contact with your dog. If you do have lice, be sure to treat yourself before you treat your dog to avoid re-infesting them.
4) Check your dog for lice regularly, especially if they often spend time around other dogs. Inspect their fur carefully for signs of small brown bugs or eggs stuck to the hair shafts close to the skin. If your dog may have lice, consult your veterinarian for treatment options.
How to Help Your Dog Recover From a Lice Infestation
Dogs who have been affected should be isolated from other dogs and not have contact with them until the entire lice treatment process is finished.
To stop your pet from becoming ill again, you’ll need to eliminate any places where they frequently spend time. This includes carpets, rugs, furniture, flooring, and outdoor areas. All of their bedding should be promptly laundered as well.
Keep unwashable items in sealed bags for 4-6 weeks to ensure any lice eggs have hatched and died–lice only survive 3-7 days off their host. Furthermore, clean all flea combs, grooming brushes, crates, collars, and leashes used for dogs. Also, wash any dog apparel.
Dogs with a heavy infestation may need extra iron, vitamins, and minerals to counteract anemia (low red blood cell levels). Most monthly flea treatments will also keep future lice problems at bay.
Dog Lice Treatment Home Remedies
Just like human lice, dog lice are tiny insects that cling to their host’s hair. Although they don’t carry any diseases, they can still cause your dog a lot of discomfort.
Fortunately, there are a few home remedies that you can use to get rid of dog lice. We’ll look at two of the most popular methods: diatomaceous earth and coconut oil.
Diatomaceous Earth
Diatomaceous earth is a natural substance that is made up of the fossilized remains of algae. It’s safe to use on dogs and effective at killing adult lice and their eggs.
To use diatomaceous earth to treat your dog’s lice, dust their coat with it using a powder puff or brush. You’ll need to do this every day for a week to completely eliminate the infestation.
Coconut Oil
Coconut oil is another safe and effective treatment for dog lice. The lauric acid in coconut oil breaks down the waxy outer layer of the louse, causing it to dehydrate and die.
To use coconut oil to treat your dog’s lice, massage it into their coat and let it sit for 30 minutes before shampooing as usual. You’ll need to do this every day for a week to completely eliminate the infestation.
Can Humans Get Dog Lice?
Most of us have had to deal with these tiny parasitic insects at some point in our lives. While lice are generally considered a nuisance, they can sometimes cause serious skin irritation and even lead to secondary bacterial infections.
But are they contagious? Can you catch them from your family pet? The answer is no. Lice that infest dogs are not the same species as head lice, which commonly affect school-aged children. In fact, it is impossible for humans to catch lice from dogs (or vice versa).
Conclusion
Although most lice are more commonly associated with humans, they can also affect dogs. So if you notice your dog scratching or shaking his head more than usual, it’s essential to take a closer look and see if he might have lice.
The good news is that lice can be treated relatively easily, so don’t hesitate to contact your veterinarian if you think your pup might be affected. In the meantime, keep an eye on him and make sure to clean his bedding and toys regularly to help prevent any further spread of the lice. Thanks for reading!
