Understanding Ear Margin Hyperkeratosis in Dogs: Symptoms, Causes & Treatment

Ear margin hyperkeratosis is a condition often observed in dogs, presenting as waxy, scaly gray or yellow skin adhering to the hair bases along the ears' edges. The hair plugs can be easily pulled out, leaving behind shiny skin. Both ears typically get affected and the condition can, in severe cases, spread from the tips of the ears, eventually covering the entire pinna.

Symptoms and Detection

While visually discomforting, this condition doesn't usually cause itching or pain. However, the ears may become swollen and heavy, prompting dogs to shake their heads. Depending on the type of the dog — dogs with long, floppy ears versus those with pointy ears — the severity of these symptoms and their apparent visibility may differ. Therefore, it is crucial for dog owners to monitor any changes in their dogs' ears in order to prevent a more grave scenario of ear margin hyperkeratosis.

Hyperkeratosis in Dogs

Hyperkeratosis is a state where the skin's outer layer thickens excessively due to overproduction of keratin. Besides ear margin hyperkeratosis, dogs may also experience nasal hyperkeratosis and footpad hyperkeratosis. Some of the symptoms include dry and thickened paw pads, crusty and flaky skin on the nose, thickened and discolored nails, skin lesions, and noticeable changes in behavior.

Cause and Handling the Condition

The exact cause of ear margin hyperkeratosis remains unknown. However, it is usually common in Dachshunds and dogs with pendulous pinnae. In extreme cases, this condition can lead to edematous and fissured ear margins, thereby adding to the discomfort of your pet. Diagnosis usually involves various methods, including physical examination, skin biopsy, blood tests, culture, and sensitivity testing. Early detection and proper treatment of hyperkeratosis in dogs can prevent adverse effects like infections, pain, and mobility difficulties.

Treatment and Prevention

Prescribed topical treatments, antiseborrheic shampoos, keratolytic products, and moisturizers are usually recommended for treatment. In the case of underlying medical conditions, medications like systemic drugs, Vitamin A, essential fatty acids, and glucocorticoids or pentoxifylline for severe inflammation and fissures may also be required. Ongoing care includes a combination of medications, lifestyle changes, and high-quality pet supplements like those offered by Rogue Pet Science.

Observation is key in managing this condition. Regular monitoring can allow early detection, thereby increasing the efficacy of the treatment and preventing the undue discomfort caused to your pet. It is always advisable to consult a veterinarian for an accurate diagnosis and the best treatment plan.
