Symptoms and Treatment of Seborrheic Dermatitis in Dogs

Symptoms of Seborrheic Dermatitis in Dogs

Seborrheic dermatitis is a skin disease where the skin, hair follicles or outer claw layer show defective keratinization and overactive oil glands, seen as a layer of yellow greasy material on the affected skin, mild itch, and in severe cases mild hair loss. It has dry and oily forms: dry signs include heavy dandruff and thinning coat; oily signs include large amounts of grease or sticky yellow-brown oil, oily dandruff stuck to the coat, and a foul odor.

The condition is more common in breeds like the Pug and Bulldog, often starting on the face, behind the ears and scalp oil glands. Without prompt treatment it easily leads to secondary inflammation and infection.

Causes of Seborrheic Dermatitis in Dogs

It is divided into primary and secondary forms. Primary seborrheic dermatitis has no underlying cause but is breed-specific — Cocker Spaniels, West Highland White Terriers, German Shepherds and Shar-Peis are prone, often appearing between 18 and 24 months. Secondary seborrheic dermatitis commonly stems from hormonal imbalance and allergies. Poor nutrition and an unclean coat can trigger it, and it often occurs alongside or follows external parasites, pyoderma and fungal skin infection due to abnormal hormones, hypothyroidism, chronic liver disease or atopy. Diagnosis is therefore complex and requires ruling out many possible causes.

Treatment of Seborrheic Dermatitis in Dogs

1. First control concurrent and secondary infections. Before the primary cause is found, treat the secondary infection, then address the specific cause. Management focuses on antibacterial and anti-inflammatory action plus supplementing missing nutrients to boost resistance. Apply an antiseptic solution to the affected area to reduce crusts and sebum, relieve itch, and promote skin renewal.

2. For pyoderma, use an antibiotic effective against Staphylococcus aureus; for Malassezia infection, apply itraconazole locally or systemically by severity.

3. For hormone-related oil secretion, take the dog to the vet for treatment and regulation, adjust the diet to reduce oily food, and supplement vitamins A and D.

4. For diet-related cases, adjust the food promptly — avoid greasy food and keep nutrition balanced, especially avoiding vitamin B deficiency.

5. For external parasite infection, fully deworm and medicate to relieve inflammation and symptoms.

Note: if the dermatitis is genetic, it’s best not to breed the dog.

The above introduces canine seborrheic dermatitis. Feed your dog sensibly, avoid overly greasy food, keep nutrition balanced, and maintain a clean environment to lower the risk.
