Skin diseases

Skin diseases in dogs can range from mild dermatitis, seborrhea to pyoderma and life-threatening superficial necrolytic dermatitis.

Some skin diseases are immune-mediated, drug-reactions and others of unknown origin (idiopathic).

Skin conditions are one of the most common presentation in cats and account for up to 20% of causes of presentation to veterinary clinics worldwide.
