Itchy skin also known as pruritus

Pruritus is the fancy medical name for itching of the skin and it is commonly seen in dogs. Pruritus is not a disease in itself but a symptom of an underlying condition.

Dogs with pruritus excessively scratch, nibble or lick their skin potentially leading to stained fur,
hair loss, sore areas, bleeding and scabs.
