Dogs like the master’s performance

Dogs sleeping with their bellies exposed is one of the signs that they like their owners. Whether it is a wild dog or an artificially domesticated pet dog, vigilance is very high, usually will not be easy to expose the belly such a “soft spot”. Therefore, only when the dog is close to the master will take the initiative to reveal the belly. Dogs are a kind of smell sensitive animals, can unambiguously distinguish the scent of different people, which is also their way to identify their owners. If a dog likes its owner, it will love the smell of its owner as well, and will often take the initiative to rub over and sniff and lick you with its tongue.
