Just like with us humans, body language and the context in which certain actions are taking place are essential in determining their meanings and figuring out the intentions behind dog’s behavior.
When it comes to dogs licking each other’s mouth, the gesture can have several meanings, but they are all benevolent.
If you see your pooch nudging another dog’s mouth with his own in an action that very much resembles kissing, he is simply saying a happy and enthusiastic hello.
If the action turns into licking, that is a pretty strong indication that the little guys are on the same page, to say the least.
If the other dog doesn’t exactly like what is going on at the moment, he might become hostile and start growling, barking or snarling.
This means that the feelings are unfortunately not mutual, and you should separate them immediately.
I Like You
Oftentimes, licking is simply a pure sign of affection. Basically, it is plain old kissing, but a little bit sloppier, obviously.
According to The Peninsula Humane Society & SPCA, it can also be an invitation to play, and the translation would probably be I like you a lot, so let’s go play!
