Types of Dermatitis in Dogs
There are several types of dermatitis in dogs, each with its own specific characteristics and causes.
Knowing the different types can help you better identify the problem and seek the most appropriate treatment.
Remember that consulting a specialist vet is the best way to identify and treat your pet correctly. Never diagnose or treat dermatitis without a specialist's opinion.
The most common types include:
1. Atopic Dermatitis
Atopic dermatitis is a chronic allergic condition that results from an exaggerated immune system response to environmental allergens such as pollen, dust mites, fungi and dust.
It is more common in certain breeds, such as Bulldogs, Labradors and Terriers.
The main symptoms include intense itching, redness and lesions on the skin, especially on the paws, face and ears.
The diagnosis of canine atopic dermatitis is challenging, as there is currently no reliable biomarker that distinguishes this disease from other dermatological disorders.
2. Contact dermatitis
Contact dermatitis occurs when a dog's skin comes into contact with irritating or allergenic substances. Cleaning products, pesticides, certain plastic materials and even some plants can trigger this condition.
Typical signs include areas of redness and irritation, usually located on parts of the body that have come into direct contact with the irritating substance.
3. Seborrheic dermatitis
Seborrheic dermatitis is caused by an imbalance in the production of oil by the dog's skin. It can result in oily skin, dandruff and an unpleasant smell.
There are two main forms: oily seborrhea (excess oil) and dry seborrhea (dry skin).
This condition can be primary (hereditary) or secondary to other illnesses such as infections or allergies.
4. Flea Allergy Dermatitis (FAD)
Flea bite allergic dermatitis is a severe allergic reaction to flea saliva. Even a single bite can cause an intense allergic response.
Symptoms include extreme itching, redness, swelling and scabs, especially on the lower back, base of the tail and back of the legs.
Strict flea control is essential to prevent this condition.
5. Trophallergic dermatitis
Trophallergic dermatitis, also known as alimentary dermatitis, is caused by an allergic reaction to certain ingredients in the dog's diet. Proteins of animal origin such as beef, chicken or dairy products are the most common allergens.
Symptoms include itching, redness, rashes and digestive problems such as diarrhea or vomiting.
Treatment involves identifying and eliminating the allergen from the dog's diet.
6. Pododermatitis
Pododermatitis is inflammation of the dog's paws, usually caused by allergies, bacterial or fungal infections, parasites or injuries.
Symptoms include swelling, redness, lesions and itching on the paws.
Treatment can include antibiotics, antifungals, parasite control and dietary changes, depending on the underlying cause.
7. Dermatological lesion
Dermatological lesions can result from various factors, including trauma, infections, allergies or autoimmune conditions. They can manifest as ulcers, sores, scabs or nodules on the dog's skin.
Veterinary assessment is essential to determine the cause of the lesions and the appropriate treatment, which can range from topical medication to more complex therapies.
8. Scabies in Dogs(Mange)
Scabies is a skin condition caused by mites that infest a dog's skin. There are two main types of mange: sarcoptic (caused by the Sarcoptes scabiei mite) and demodectic (caused by the Demodex canis mite).
Symptoms include intense itching, redness, hair loss and scabs on the skin.
Treatment usually involves the use of specific medication to eliminate the mites and relieve skin irritation.
9. Malassezia dermatitis
Malassezia dermatitis is caused by an overgrowth of the fungus Malassezia pachydermatis on the dog's skin. This condition is most common in moist, warm areas of the body, such as the ears, folds of skin and between the toes.
Symptoms include itching, redness, an unpleasant odor and darkening of the skin.
Treatment can include the use of antifungal shampoos and oral or topical medication to control the infection.
10. Dermatitis Pyodermatitis (Acute Wet Dermatitis)
Pyodermatitis, also known as acute moist dermatitis, is an inflammation of the skin that occurs rapidly and is characterized by moist, red areas, often caused by excessive licking or biting.
This could be the result of an allergy, insect bite or other irritation.
Treatment can include cleaning the affected area, using anti-inflammatory medication and, in some cases, antibiotics to prevent secondary infections.
11. Allergic Contact Dermatitis
Allergic contact dermatitis is an inflammatory skin reaction that occurs when a dog comes into contact with an allergenic or irritating substance. This can include cleaning products, certain types of plants, or even flea products.
Symptoms include redness, itching and lesions in the contact area. Treatment usually involves identifying and removing the allergen, as well as topical care and medication prescribed by the vet.
12. Acral dermatitis due to licking
Acral lick dermatitis is a chronic condition where the dog licks a specific area of the body excessively, usually the paws, causing lesions and infections. This can be triggered by stress, boredom or anxiety.
Treatment includes addressing the underlying cause of the behavior, as well as topical care and, in some cases, the use of Elizabethan collars to prevent licking.
13. Coppery dermatitis
Coppery dermatitis is caused by an overgrowth of bacteria or fungi in damp, poorly ventilated areas of the skin, such as the skin folds. It is common in breeds with many skin folds, such as Bulldogs and Shar Peis.
Symptoms include itching, redness, bad smell and discharge. Treatment involves keeping the affected area clean and dry, as well as using antibacterial or antifungal medication.
14. Solar dermatitis
Solar dermatitis is an inflammatory reaction of the skin caused by excessive exposure to the sun. It is more common in dogs with short coats and fair skin.
Symptoms include redness, scaling and, in severe cases, ulcers. Prevention is the best approach, including the use of animal-specific sunscreen and limiting sun exposure time.
Diagnosis
Well, how is canine dermatitis diagnosed? As I said earlier, in order to diagnose dog dermatitis, it is essential to consult a vet. And it can vary from professional to professional.
The veterinary specialist can carry out physical examinations, allergy tests, skin scrapings, blood tests and other procedures to identify the exact cause of the dermatitis.
Treatment
The diversity of causes of canine dermatitis means that treatment must also be varied and adapted to the specific origin of the problem.
The vet is the professional qualified to determine the best approach, which may include a combination of different methods, such as:
- Shampoos and Lotions
- Ointments and creams
- Oral Medicines
- Parasite Control
- Diet adjustments
For successful treatment, it is essential to simultaneously address the various factors that influence the pruritus threshold, especially during flare-ups.
It is important that treatment is always individualized and adjusted as necessary, taking into account crises, seasonality and the patient's general health.
Effective communication between veterinarian and guardian is fundamental to the successful treatment of any dog with atopic dermatitis.
How to Avoid
Preventing dermatitis in dogs involves several practices:
- Maintain your pet's regular hygiene, including bathing with suitable shampoos.
- Control parasites with products recommended by the vet.
- Offer a balanced and adequate diet to avoid food allergies.
- Avoid contact with irritating or allergenic substances.
- Have regular check-ups at the vet to monitor your dog's health.
Canine dermatitis can range from mild conditions to more complex problems. However, with regular monitoring by a veterinarian, these conditions can be effectively controlled or even resolved.
