 Superficial pyoderma describes '''cutaneous bacterial infection''' that is confined to the stratum corneum of the interfollicular skin and hair follicles. Normal [[Skin - Anatomy & Physiology|skin]] is colonised by a variety of resident bacterial and fungal organisms. They are not normally pathogenic and sometimes help prevent colonisation of pathogenic species through niche competition.

 Changes to the microenvironment of the skin lead to the development of conditions '''favouring the growth''' of these pathogenic staphylococci. Inflammatory reactions to bacterial products can lead to further multiplication of bacteria.

 Superficial pyodermas are '''not usually pruritic''', although some dogs exhibit marked pruritus presumably due to a hypersensitivity to the bacteria.
