Bacterial folliculitis in dogs is usually caused by a staphylococcus. It is more common to occur in the lower part of the body, especially in the armpits, abdomen and English.

Folliculitis can be a disorder primary or secondary to other diseases such as scabies, seborrhea or pyoderma. This is because, in general, a healthy animal will have a good immune system and a skin barrier that defends it from pathogens. It is when there is a failure in these protection mechanisms, as in a dermatological pathology, that an access path is opened for the appearance of disorders such as folliculitis. In puppies and young dogs it can be explained by a still immature immune system.

Causes of folliculitis in dogs

Among the causes we can talk, as we have said, about others diseases that affect the skin.

To prevent it, it is advisable that we use a brush adapted to the characteristics of our dog. The dog groomer or the veterinarian can recommend the best tools.

A poor hygiene, seborrhea, parasitosis by fleas or mites, as well as a poor quality diet can be related to the appearance of canine folliculitis.

In its center the hair shaft is located. These hairs will end up falling, leaving an injury called epidermal collar. This would be the typical picture of superficial folliculitis in dogs, a very common infection.

When deeper skin involvement occurs, large boils are formed that eventually open, releasing pus, after which a scab forms on them. In the most severe cases of deep folliculitis they develop fistulasdrainage. If folliculitis is chronic we will see alopecia, hyperpigmentation, that is, a darkening of the skin, and lichenification, which is its thickening.

In contrast, in deep folliculitis, both topical and systemic products must be used. In addition, if the dog is long-haired, it is recommended to cut it in all areas that have been affected by folliculitis. In these races it is possible that the density of the mantle does not allow us to observe the initial symptoms. We will detect only peeling and matte hair.

Baths in these more serious cases are recommended more frequently, even a couple of times a day until improvement is observed, at which time we can follow the pattern we have commented for cases of mild folliculitis. Treatment should continue until full recovery. In addition, it is recommended that antibiotics that are prescribed are chosen on the basis of a crop and that its administration be continued a couple of weeks after healing, since withdrawing it early may cause a relapse.

As we have seen in the sections for the most common causes, poor hygiene or improper feeding can lead to the appearance of this infection, which is why paying attention to these factors is so important. Likewise, although canine folliculitis is caused by a disease, apart from veterinary treatment, as a home remedy we recommend offering an adequate diet to the animal as well, since this will not only favor its speedy recovery, but will also provide a better state of health For the rest of his life. For this, we can opt for a homemade diet, based on natural food with quality ingredients, such as meats, fish, fruits and vegetables.

On the other hand, and continuing with home remedies for folliculitis in dogs, chamomile or any other natural painkiller like tea or oatmeal They can be applied on damaged skin, always consulting with our veterinarian. Of course, they do not replace the prescribed drug treatment.
