When these glands are active, they leave the nose and paw pads slightly moist and help these specialized skin features maintain their functional properties. [4] The odor associated with dog paw pads is much more noticeable on dogs with moist paw pads than on those with dry pads. Dogs also have numerous apocrine glands in their external ear canals.
The violet gland or supracaudal gland is a gland located on the upper surface of the tail of certain mammals, including European badgers and canids such as foxes, wolves, [1] and the domestic dog, [2] as well as the domestic cat.
