Do you want to know all the aspects of ringworm in dogs? In the following article, we explain the causes, symptoms, and treatments of this disease that can affect your dog.
The ringworm in dogs or dermatophytosis is a superficial mycosis whose etiological agents are varied. These invade our pets’ keratinized tissues (skin, hair, and nails), giving lesions known as ringworms.
Normally this infection is cutaneous without going through the stratum corneum, so it does not affect deep tissues or organs in animals with a good immune system. The genera of fungi involved in this process are:
These dermatophytes feed on keratin (a protein whose function is protection). They have keratinolytic activity; that is, they can use keratin as nutrients by means of enzymes (keratinases). The dermatophytes are classified as:
Regarding its epidemiology, we can say that it is a disease with worldwide distribution. It affects more young animals, and its transmission mechanism is direct. In addition to age, other risk factors are overcrowding, poor diet, handling, and hygiene or not complying with the quarantine periods.
Yes, ringworm in dogs is considered a zoonosis. According to the World Health Organization (WHO), a zoonosis is “that disease that is transmitted naturally from vertebrate animals to man and vice versa.” The contagion is carried out through direct contact with the fungus spores from the skin of dogs with the skin of humans.
In most people, these infections are mild and do not have many complications. The problem is when people have a depressed immune system, for example, people with AIDS. In these cases, the infections will be more persistent.

The severity of these symptoms depends on the virulence of the strain, the place where the disease will occur, or the individual himself. The clinical signs are highly variable and can be seen between 2 and 4 weeks.
This period may decrease in animals with a suppressed immune system. The most characteristic symptom is alopecia (circular lesions), due to the affected hairs’ breakage. Sometimes there is inflammation, and the itching is variable.
If the diagnosis is made in the initial stages, it will be much more favorable for the treatment and in animals, as well as to avoid a public health problem and spread it to humans. So, do not hesitate to go to your vet whenever you see an anomaly in your pet.
The veterinarian must take an anamnesis, that is, the data of the animal’s medical history. A thorough physical examination is also performed in order to see the physical condition of the animal and the possible injuries that it may present. Once these steps have been completed, the assertive diagnosis is carried out using different tools:

Dermatophytosis is a self-limiting infection; that is, the symptoms resolve on their own after a while, in this case, between 1 and 3 months. So just by improving the animal’s immune system, it ends up remitting on its own. In addition to this, the treatment will consist of symptom relief and isolation to avoid contagion to other animals and humans.
In dogs or dermatophytosis, ringworm is an infection caused by fungi that produce lesions in the keratinized tissues of both animals and humans, being a zoonotic disease. It is very important to be aware of the importance of going to the veterinarian to make the diagnosis and dictate the treatment guidelines for possible diseases. With this, we will improve our animals’ health;
we can avoid possible infections to other animals and a public health problem by avoiding contagion to people. For that, give your pet a good quality of life, a good diet, physical exercise, and comply with the vaccination guidelines and deworming. Also, keep your dog and the areas where it will live in good cleanliness and hygiene conditions.
