Ridding your dog of external parasites (ticks, lice, mites)

All dogs are likely to be infested with external parasites. We need to make sure that they are well protected against them, because it's about their well-being and their health.

The dogs can be infested by different types of external parasites . Some are a little bigger and therefore more visible than others, but whatever their size, they must all be removed to preserve the well-being and health of our canine companions. Those around them - including ourselves - can also suffer from these infestations that cause illness and inconvenience .


The ticks feed on the blood of the animal host on which they are fixed. By being numerous to infest a dog, they can cause anemia in the latter. The consequences of an animal infestation with ticks can be even more serious: these mites are vectors of serious diseases for the dog, such as piroplasmosis , ehrlichiosis or Lyme disease (or borelose). In some cases, their misdeeds are likely to be fatal .

It is therefore necessary to protect the dog and protect himself by acting first as a preventive . For this, the environment of the animal must always be clean and healthy . The dog should be brushed regularly to detect and remove any larvae and prevent them from multiplying.

An anti-tick spray or pipette treatment can prevent, but also treat infestations. Sometimes ticks must be removed manually. This operation should be done with the help of a pull-tick , because it avoids leaving the "head" of the parasite in the skin of the dog.

The lice of the dog

The dog lice are specific to the canine species. They are not transmitted to other living beings, but can be transmitted to other congeners by close contact.

Lice and eggs (nits) feed on skin debris (this is the case of Trichodectes canis) and blood (Linognathus setosus) of the host dog.

To eradicate them, we use a specific insecticidal shampoo whose application is to be repeated several times in order to be sure to eliminate all the eggs. If several dogs share the same environment, all must be treated.


In addition to ticks, other species of mites can infect dogs, such as chiggers and scabies . These tiny parasites settle on the skin of their hosts and feed on their blood. The infested dog then suffers from redness and itching . Significant hair losses are also observed, as is the appearance of crusts .

The treatments consist of repeated administrations of acaricides in liquid form on the affected areas. Again, it is essential to clean up the dog's environment to prevent new infestations.


The fleas are external parasites most common in dogs. These can be infested at any time of the year. Fleas, the main species of which is Ctenocephalides felis , cause irritation and pruriginous (itchy) papules by pricking the animal. In addition, some dogs are allergic to their saliva, injected into the skin during the bite.

To treat fleas , you must wash your dog using anti-flea and anti-tick shampoo to eliminate a good part. The use of a spray or a pipette may be necessary if this was not enough. It is important to apply the instructions of the instructions to the letter (possibility or not to bathe the dog, minimum delay between 2 applications, etc.), to ensure that the environment of the animal is clean and to treat other animals that rub shoulders with it.
