Dogs regulate their body temperature differently from humans. They do not sweat through their skin the way humans do; instead, they only have sweat glands on their paw pads, between the toes. Their main cooling mechanism is panting, which is far less effective than the full-body sweating humans rely on. As a result, dogs are more susceptible to overheating and require extra care in hot weather. Ensuring your dog has access to fresh water at all times is crucial during the summer.
