Dogs do sweat, but not like humans. They have sweat glands in their paw pads and on their nose, but they don't produce very much sweat.
Dogs cool down by panting, vasodilation, and sweating. Panting is their most effective way to cool down.
Dogs sweat through their paw pads. You may notice wet paw prints on the floor on a hot day. The sweat helps to cool down their paws and their body.
Dogs also have apocrine sweat glands throughout their body. These glands produce sweat that contains pheromones, which dogs use to communicate with each other.
Dogs also have merocrine sweat glands in their paw pads. These glands produce sweat that helps to cool down their paws.
Heatstroke is a serious condition that can occur when a dog's body temperature gets too high.
Take your dog for walks or runs early in the morning or late in the evening when it is cooler.
