What are the only places that dogs have sweat glands?

Dogs have sweat glands primarily in their paw pads and, to a lesser extent, in their noses. Unlike humans, they do not rely heavily on sweating to regulate their body temperature. Instead, dogs primarily cool themselves through panting. The sweat glands in the paw pads help with grip and provide some thermoregulation, but their main cooling mechanism is still the respiratory system.
