The reasons why short-haired dogs are relatively prone to skin diseases may be as follows:

More skin exposure : The skin surface of short-haired dogs is more easily exposed to the external environment and lacks the protection of hair.

Lack of natural barrier: Hair can play a role in isolation and protection. Short-haired dogs have shorter hair. The lack of this natural barrier increases the risk of skin diseases.

Skin is more prone to dryness: Short-haired dogs’ skin may lose moisture more easily and become dry.

More susceptible to external stimuli: The skin of short-haired dogs is more likely to come into contact with external irritants such as dust, pollen, and grass, which may cause allergic or inflammatory reactions.

Autoimmune issues: Certain short-haired dog breeds may have inherited skin problems or autoimmune diseases, making them more susceptible to skin diseases.
