What this symptom means clinically

Thin skin means reduction or degeneration of epidermal and dermal support such as collagen and subcutaneous fat, making skin fragile. Long-term glucocorticoid exposure, endocrine imbalance, and age-related collagen loss are common mechanisms.

🐱 In cats

In cats, thin skin is more often linked to chronic medication exposure or rare endocrine disease and may show visible vessels and small wounds.

🐶 In dogs

In dogs, thin skin is often related to chronic systemic or topical steroid exposure, Cushing’s disease, or other endocrine disorders.
