Pediculosis (Parasitic Infection with Lice, Lice Infestation) in Dogs
- Occurrence: rarer
- Location of illness: Skin/Fur
Pediculosis in dogs is a parasitic infection caused by lice infestation. These small insects live on the surface of the dog’s skin and feed on blood, dander, or other bodily fluids.
The most important facts at a glance
Pediculosis in dogs is a parasitic infestation caused by lice, which are wingless insects that spread through direct contact. There are two main types of lice that infest dogs: sucking lice, which feed on the dog’s blood, and chewing lice, which feed on dander. The life cycle of a louse includes the egg, nymph, and adult louse stages and lasts about three to four weeks. Lice are specialized parasites and usually only infest their specific hosts, which is why dog lice usually do not infect humans.
Symptoms of a lice infestation include Itching, poor coat quality, Scratching, and Hair loss, especially in the area of the ears, neck, and shoulders. In rare cases, anemia may occur. Diagnosis is made by a thorough examination of the dog’s coat and skin by the veterinarian, often with the aid of a magnifying glass or microscopic examination. Blood tests can provide additional information about the state of health.
Treatment includes insecticidal shampoos, sprays, or spot-on preparations that kill all stages of the lice. It is important to thoroughly clean the dog’s environment to prevent re-infection. In cases of Skin infections, antibiotics or anti-inflammatory drugs may be necessary. The prognosis is generally good if the infestation is detected and treated early. Regular grooming and physical examinations, as well as a clean environment, help to prevent infestation.
Causes
Lice are wingless insects that spread through direct contact from one host to another. There are two main types of lice that can infest dogs: sucking lice (Anoplura) and chewing lice (Mallophaga). The sucking lice feed on the host’s blood, while the chewing lice feed on dander and other superficial materials.
The life cycle of a louse consists of three stages: egg, nymph, and adult louse. The eggs, also called nits, are attached to the hairs of the host and hatch into nymphs after about a week. These go through several molts before they mature into adult lice, which in turn are able to reproduce. The entire life cycle takes about three to four weeks.
Lice are highly specific parasites, meaning that they usually only feed on a specific host type. Therefore, lice that infest dogs are usually not able to infect humans or other animals. Lice infestations are more common in environments where many dogs live together in close quarters, such as in kennels or animal shelters.

The most common symptoms of a lice infestation in dogs are Itching and discomfort. Dogs with pediculosis often Scratching and bite themselves intensely to relieve the Itching. This can lead to skin irritation, Inflammatory conditions, and even secondary Skin infections.
In severe cases, Hair loss may occur, especially in areas that have been heavily scratched or bitten. In some cases, small, red papules or Crusts may also be visible on the skin. Anemia can occur with sucking lice, especially in young or weakened dogs.
To recognize the lice themselves, you have to examine the dog’s hair carefully. The lice are small, but visible to the naked eye, and appear as tiny, moving dots on the skin or in the coat. The nits are visible as small, white or yellowish eggs on the hair strands.
Diagnosis
The diagnosis of a lice infestation is usually made by a thorough physical examination of the dog. The veterinarian will carefully examine the dog’s coat and skin to look for adult lice or nits. A magnifying glass can be helpful to make the parasites more visible.
In addition, the veterinarian may take a sample of the coat or skin to examine it under a microscope. This can help identify the type of lice and rule out other possible causes for the symptoms.
In some cases, blood tests may also be performed, especially if there are signs of anemia or other health problems. These tests can help assess the dog’s general health and detect any concomitant diseases.
Therapy
Treatment for pediculosis in dogs typically involves the use of insecticidal shampoos, sprays, or spot-on treatments specifically designed to kill lice. It is important to follow the veterinarian’s instructions carefully and continue treatment for the entire recommended period to ensure that all stages of the lice, including the nits, are killed.
In addition, it is important to thoroughly clean the dog’s environment. Bedding, blankets, pillows, and other items that the dog has come into contact with should be washed or disposed of to prevent re-infection. Regular vacuuming and cleaning of living areas can also help eliminate any remaining lice.
In cases of secondary skin infections or other health problems, the veterinarian may prescribe additional treatments such as antibiotics or anti-inflammatory medications. These help to relieve the symptoms and promote healing of the skin.
Prognosis and follow-up care
The prognosis for dogs with pediculosis is generally very good, especially if the infection is detected and treated early. With appropriate treatment and care, most dogs recover completely and show no long-term health problems.
In rare cases, especially with severe infestations or in dogs with weakened immune systems, it may take longer for all symptoms to disappear. It is important to follow the veterinarian’s instructions and have regular check-ups to ensure that the treatment is effective and that there is no re-infection.
Prevention
To prevent a lice infestation in dogs, it is important to perform regular grooming and physical examinations. Be sure to brush your dog regularly and look for signs of parasites, especially if he comes into contact with other dogs.
In situations where many dogs live together in close quarters, such as in animal shelters or breeding facilities, regular checks and preventive treatments should be considered. The use of prophylactic agents can help reduce the risk of lice infestation.
In addition, the dog’s environment should be kept clean and free of parasites. Regular cleaning of sleeping areas and living areas can help minimize the risk of infection. If a lice infestation is suspected, it is important to act quickly and consult the veterinarian to ensure appropriate treatment.
