Skin Disorders (Pigment-Related Dermatitis & Sun Sensitivity)
Dogs with white coats and lack of pigment are prone to sunburn and related skin disorders, including chronic dermatitis and increased risk of skin tumors.
Detailed Description
Lack of skin pigment increases susceptibility to UV-induced skin damage, leading to sunburn, chronic dermatitis, and a higher risk of skin tumors such as squamous cell carcinoma. Chronic exposure can cause thickening, ulceration, and secondary infections, especially in breeds with predominantly white coats.
Common Symptoms
- Redness
- Scaling
- Hair loss
- Ulceration
- Chronic thickening
- Non-healing wounds
Management Options
- Sun avoidance
- Protective clothing
- Dog-safe sunscreens
- Topical or systemic antibiotics for secondary infections
