Are lice in dogs?


Попробуем разобраться, действительно ли у собак могут быть вши

To begin with, lice in dogs do exist - this is a scientific fact. And they tormented four-legged friend no less than human lice people. Like humans, lice in dogs are of several different types, differing from one another in the features of biology and the structure of the body:

  • the canine louse itself (Linognathus setosus) is a small yellow-gray parasite that causes constant concern to the animal, combing the skin, and in case of severe infection, the pet's thinning;
  • canine jerk (Trichodectes canis) - about the same size as the louse, but when infecting causes hair loss, dermatitis and permanent itching.

Below the photos show the canine louse and withered:

These two parasites are very easy to confuse, but there will be no trouble, since the struggle with them is approximately the same. The main thing here is to be able to detect them on the dog even before serious consequences occur.

In addition to the fact that these parasites cause damage to the wool cover and dermatitis, withers still carry very dangerous helminths, and they are often found in dogs. Therefore, to know how to look like lice and withers in dogs, as well as how to quickly bring them out of the pet will be useful to the owner of a dog of any breed.

Infection of a dog with lice is called sifunkulatozom.

Lifestyle and appearance of lice in dogs



Lice in dogs look like very small insects of yellowish-gray or light gray with an elongated calf. Lice from withers are difficult to notice, and such differences can be noticed only with due experience and careful consideration of parasites:

  • the louse has a long, elongated and narrow body, while it is dense and wide
  • the withers have a large semi-square head, while in lice it is much narrower.

These signs are clearly visible if you hold a living adult insect on your hand.

So, for example, lice look in dogs (close-up photograph):

There are differences in the lifestyle of lice and withers. Dog lice feed on the blood of the animal - their oral apparatus is adapted only for piercing the skin and sucking blood. Vlasoids, on the other hand, feed mainly on the exfoliating skin, hair and secretions of the skin glands of the animal.

Flea lice are distinguished by a light body and an inability to jump. In addition, the louse is easily crushed between the fingers, while crushing the flea is extremely difficult because of its very durable chitinous shell.

Dog lice can not infect other animals - they are strictly specific to one type of host, and can only parasitize on dogs. This means that a person or a cat can not get lice from a dog.

Lice in dogs multiply, gluing their eggs to the hairs. The sticky shell of the egg quickly hardens in the air, and it's very difficult to remove all such construction from the wool.

An egg with a shell is called a nit, following the example of human lice. Nits are very resistant to the effects of adverse environmental factors and even tolerate the treatment of animal fur by many modern insecticides.

On a note

When a large number of lice cause the cohesion of hair hairs in the dog, resulting in the formation of collars. This is especially true for long-haired breeds: they have parasites in the wool may not be noticeable, but the appearance of felted wool is a good diagnostic sign of the presence of insects.

Lice in dogs with little infection in the eyes do not rush, but in pets of dark rocks, even at the initial stages of infection, it is usually easy to notice: lice themselves and their nits look lighter against the background of dark hair.

Vlso-eaters are more common in dogs than lice, but in general both these and other parasites are much less common than fleas.

Why are lice dangerous for dogs?

The danger of lice in dogs lies primarily in the fact that they cause constant itching with their bites. The same is true for withers - they, though they do not bite directly, but constantly scrape the skin and can gnaw it to sensitive layers.

Consequences of severe infection with lice in dogs can be:

  • loss of hair, the appearance of bald patches and general deterioration of the state of the wool cover (see photo) Признаками вшивости у собак могут быть проплешины и раны на теле
  • allergy to bites
  • dermatitis, developing on the ground permanent scratching, eczema and neurodermatitis Дерматит у собаки может появиться вследствие регулярных и массовых укусов вшей
  • anemia with a lot of daily bites
  • slimming and exhaustion of a dog
  • infection with helminths, in particular - cucumber chain.

Especially dangerous lice in puppies: in infants when infected, there may be growth retardation, weakening of the immune system, constant depression. That's why if lice have appeared in a dog, they should be removed as soon as possible.

How do dogs become infected with lice?



In most cases, lice are transferred from a sick animal to a healthy one by close contact - play, sleep, mating, in a fight.

Avoiding such contacts is very difficult, and even a sufficiently well-groomed domestic dog can be infected - until its owner has noticed the parasites.

Often, the owners themselves infect pets, bringing on the clothing of other animals' hair from the street or from the guests. When infected with lice, the dog loses individual hairs especially intensively, and therefore it is more likely that such hairs with insects or their eggs will fall on the clothes of a person's petted animal.

Treatment of a dog against lice

To deduce lice in a dog as a whole is not difficult. Since neither lice nor worm eaters, unlike fleas, can not escape from the animal, they will die by treatment with any effective insecticidal drug.

Treatment of lice in dogs can be carried out by the following means:

  • Insectoacaricidal drops on the withers - these funds are suitable for all breeds of dogs, and some - even for puppies. Especially known drops Stronghold, Frontline, Hartz, Bars. In the range of each manufacturer there are preparations for dogs of different breeds and ages, so it is not difficult to choose the most suitable drops. Apply them as follows: from the pipette, liquid drips onto the withers near the back of the dog (some preparations - in several places along the spine) and carefully rubbed into the skin. After this, through the network of subcutaneous blood vessels, the insecticide spreads throughout the body and poisons parasites that suck blood or feed on the animal's skin. Drops are the most easy to use tools that last for a long time. Only occasionally they can cause an allergy in the animal. Капли на холку Стронгхолд
  • Sprays, many of which are suitable even for puppies. These remedies are good because they rarely cause allergies, but have only a small residual effect. To remove lice with their help, spray it is necessary to treat as much as possible all the hair in the dog, to keep the drug for several hours and wash it off. Lice in a puppy can be destroyed by Front Line and Hartz sprays - these drugs even with some ingestion in the digestive tract do not lead to the appearance of side effects. In adult dogs, you can also use sprays Bars, Blochnet and Advantage. Спрей Hartz можно использовать не только против блох и клещей, но также против собачьих вшей и власоедов
  • Insecticidal shampoos - they are most suitable for puppies and dogs of decorative breeds. The most famous are the dog breeders RolfClub, Phytoelita and Lugovoi. Shampoo is simply applied to wet hair, foams, aged for 15-20 minutes and washed off. Shampoos are mostly non-allergenic, fast acting, but quite expensive and difficult to handle large dogs.

Sometimes it is recommended to use flea collars from lice and withers in dogs. Indeed, the collars will allow for a week or two to remove lice, but they often cause allergies and damage to the coat on the place of wearing. It is sensible to use collars for dogs permanently living outside the room as a preventive measure against infection with lice and fleas.

Once the lice are removed from the dog, it is necessary to etch the worms.

Safety and precautions when removing lice

When using any remedy for lice, remember about contraindications and possible side effects.

Most of the drugs can not be used for pregnant and lactating dogs, puppies under the age of up to one month, and dogs weakened by diseases - infectious or somatic.

Если собака дополнительно ослаблена болезнью, применять инсектицидные средства нужно с особенной осторожностью

In these situations, you should always choose a specialized drug.

However, in any case, pregnant women, puppies, and sick dogs from lice need to be rid of, as these parasites can aggravate any health problems in the animal. It is reasonable in these situations to seek advice from a vet.

In order to protect the pet from infection with lice (and other parasites), you should make sure that the dog does not communicate with stray animals. It is useful to wear a collar of fleas for the duration of walking. And the owners themselves after returning from the guests who have animals, or with long walks in the street with neighbors, it is worthwhile, without going into the house, to clean clothes with a thick brush. Such measures will be enough to ensure that your dog has never learned what lice and withers are.
