Dogs have sweat glands in their nose and where else?
Apocrine sweat gland glands, which produce ear wax; and the mammary glands, which produce milk. The rest of the body is covered by eccrine sweat glands. Most non-primate mammals, however, have apocrine sweat glands over the greater part of their body. Domestic animals such as dogs and cats have apocrine glands at each hair follicle but eccrine glands only in foot pads and snout. Their apocrine glands, like those in humans, produce an odorless, oily, opaque secretion that gains its characteristic odor upon bacterial decomposition. Eccrine glands on their paws increase friction and prevent them from slipping when fleeing from danger. The apocrine
Sweat gland in foot pads and snout. Their apocrine glands, like those in humans, produce an odorless oily milky secretion evolved not to evaporate and cool but rather coat and stick to hair so odor-causing bacteria can grow on it. Eccrine glands on their foot pads, like those on palms and soles of humans, did not evolve to cool either but rather increase friction and enhance grip. Dogs and cats have apocrine glands that are specialized in both structure and function located at the eyelids (Moll's glands), ears (ceruminous glands), anal sac, prepuce vulva, and circumanal area. Eccrine sweat glands are everywhere
