Also, some diseases of the skin and hair are congenital (manifested from birth or shortly after). While many others are acquired throughout the life of the animal.

Types of canine dermatoses:

Skin diseases in dogs can be classified according to the cause that causes them, or the symptom and main location of the lesions:

Infectious: pyoderma (infection of the skin) is caused by bacteria such as Staphylococcus spp. Viruses such as feline leukemia or yeasts such as Malassezia spp, also cause skin problems.

Parasitic: the most frequent are mange, caused by mites, such as Sarcoptic or Demodex.

Allergic and immune-mediated:

The immune system sometimes overreacts to foreign substances or substances, as in the case of atopy, food allergy. Allergic dermatitis to flea bite (DAPP), pemphigus or canine lupus.


Benign tumors, such as basophilia, may appear on the skin, or malignant ones, such as squamous cell carcinoma.


Some dermatopathies are characterized by partial or total loss of hair. And maybe of inflammatory, endocrine (hypothyroidism, sex hormones), or non-inflammatory congenital (follicular dysplasia) origin.


Affects the most superficial layer, causing peeling. Some examples are sebaceous adenitis or primary seborrhea.

1. Predisposing factors to dermatological problems according to the races

Some dog breeds are more likely to suffer dermatopathies.

A) Yes:

It is easy to diagnose atopy in the West Highland white terrier or the French bulldog. Deep pyoderma is typical of the German shepherd. Keratinization disorders are common in Cocker Spaniel or Schnauzer. The tumors such as melanoma appear as the Golden retriever dogs.

Dog Skin diseases: Causes, Symptoms, and Treatment of  the Most Common Canine Dermatoses

There are many diseases that affect the dog’s skin. In some cases, they can be manifestations of other health problems. Know the causes, symptoms, and treatment of the most common canine dermatoses.

Dermatological lesions in dogs: symptoms and diagnosis

Since the dog’s skin is an external organ. It is easy to recognize changes in it. The difficulty lies in the accurate diagnosis of canine dermatopathy. Since these diseases share signs and symptoms and can be confused with each other. therefore, the first step in the consultation of the veterinarian is to collect information about the symptoms and injuries. That we have seen in our pet, the time of appearance. If there is itching (itching). What are the dog’s habits (feeding, habitat)? If you are worm correctly, and even if we have observed similar lesions on our skin. Which may be indicative of an infectious or parasitic process.

Canine dermatological injuries and associated diseases

The signs and symptoms of a disease that can be found in canine dermatological problems are given specific names. These are the main ones:


It is synonymous with itching, which induces the dog to scratch to relieve it. Typical of allergic or infectious dermatopathies such as pyoderma, Malassezia overgrowth, or otitis.


Is the loss of hair, derive from scratching or a failure in the growth cycle of the follicle. As in endocrine dermatopathies (hypothyroidism, Cushing’s syndrome).


Reddening of the skin, a sign of inflammation, frequent in allergic dermatoses, and infectious or parasitic.


Are small rounded elevations of the skin. They appear in allergic or parasitic dermatoses such as scabies.


Similar to papules but with purulent content typical of pyoderma and bacterial folliculitis.


Are superficial hardened scales resulting from wound healing or keratinization disorders? They can be visualized in allergic and immunomodulated dermatoses. Such as pemphigus, and even parasitic, such as leishmaniasis.

Nodules and masses:

They are rounded or flattened, on the skin or below it. We usually find them in fungal infections and neoplasms.

Erosions and ulcerations:

Areas where the skin is destroyed, exposing deeper layers, usually painful and exudative.

Diagnosis of skin diseases

Diagnosis of skin diseases or canine dermatoses. After collecting data and scanning the dog for dermatological lesions. The next step is to perform tests to guide and confirm the diagnosis of canine dermatosis:

Cutaneous cytology:

Consists of taking a small sample of the lesion, using a fine needle puncture (FAP) or opposition. It is fixed and stains and observe under the microscope to visualize inflammatory or tumor cells, bacteria, fungi or parasites.

Skin scraping:

Sample of the skin is taken with the help of a scalpel. Then observe under a microscope. Some mange mites can be diagnosed by this technique.


Consists of pulling out complete hair follicles to detect structural anomalies (dysplasia’s) or the presence of dermatophyte fungi or scabies mites.

Culture and antibiogram:

In the case of a bacterial or fungal infection, a sample is sent to the laboratory to determine. The pathogen and choose the most appropriate drug to eliminate it.


It is the taking of a sample of the skin in all its extension to study it under a microscope. Essential for the diagnosis of neoplasms.

Detection of antibodies and intradermal reaction:

Commonly known as “allergy tests”, to detect the reaction against allergens.

Skin diseases in dogs

There are many diseases that affect the dog’s skin. In some cases, they can be manifestations of other health problems. Know the causes, symptoms, and treatment of the most common canine dermatoses.

Treatment of skin diseases in dogs

The therapeutic approach of skin diseases in dogs must be multimodal. Gathering all means to alleviate the symptoms suffered by the pet. And eliminate, primarily, the primary cause that causes them. To achieve this, there are several options that we explain below from drugs to hygiene products through nutritional changes.

Pharmacological treatment and immunotherapy

Anti-inflammatories and immunosuppressants:

For the treatment of atopic dermatitis, allergic reactions, and autoimmune diseases. The use of corticosteroids or ciclosporin is resorted to.


Are drugs to relieve pruritus specifically, such as oclacitinib and lokivetmab.

Antibiotics and antifungals:

For the treatment of bacterial or fungal infections, respectively. In topical infections. Topical application is sufficient but in severe cases, it is necessary to administer them systemically.


Are Medicines to Treat scabies.

Traditionally, ivermectin’s are used topically. In the form of a pipette. Currently, isoxazolines are modern and innocuous drugs that are administered orally to treat external parasites: fleas, ticks and some scabies mites.


It is an individual treatment against environmental allergy that consists in the application of small amounts of allergens so that the organism accepts them and does not generate a defensive response to them.

Hydrotherapy and shampoo therapy

In many dermatological conditions, water is lost through damaged skin. Therefore, baths with water and the application of shampoos are very beneficial. There are emollient shampoos (soften skin), moisturizers (create a barrier to prevent water loss), antipruritic (control the itching), or antiseptics (slow the growth of microorganisms).

Initially, several weekly baths are applied, to then carry out one or two monthly maintenance baths. They can be combined with the use of foams, gels or creams, with the same therapeutic properties.

Food and nutritional supplements

A bad diet can negatively influence the skin health of our dogs. In order to make your hair and skin look healthy and shiny. We must look for a feed without preservatives or colorings. With a source of reliable protein, avoiding by-products. A complete feed without cereals and with a novel protein is essential for the treatment of food allergies. Additionally, we can use essential fatty acids, such as EPA and DHA, already present in many commercial feeds or in the form of capsules, oral solution or pipettes. Some minerals and vitamins for dogs, such as biotin (or vitamin H), vitamin C, zinc and copper help maintain strong hair and prevent skin oxidation. Your usual veterinarian will show you the perfect combination for your best friend.
