Why do dogs like to sniff each other’s bottoms

There are two scent glands on the dog’s buttocks, which are what we usually call the “dog smell” emitting points. Dogs can get information about other dogs’ hidden bodies through the scent emitted by the scent glands. 2, smell if they know the dog Dogs also need friends, but because dogs can not remember other dogs through eye memory like humans, so they can only identify each other by the smell emitted from their buttocks to confirm whether they are friends or strange dogs. 3、Determining male and female Dogs communicate through scent, so they can determine whether a dog is male or female by sniffing their bottom. Because female dogs in heat will secrete a special smell, male dogs will be able to choose a partner through these smells. The last reason why dogs sniff each other’s butts is actually a socialization activity between dogs, just like waving hello when we see someone we know.
