<human>:  Why do dogs have a snout?
<bot>: The snout is a very important part of a dog’s anatomy. It helps them to sniff out things. Dogs have a very good sense of smell. A dog’s nose is made up of many different parts. The nostrils are located on either side of the snout, and they are used to inhale air. The upper lip is covered with tiny hairs that help to trap smells. The roof of the mouth contains taste buds, which help dogs to determine the flavor of their food. The tongue is used to push food into the dog’s mouth.
