I have no idea. Such a thing seems very inappropriate and out of the ordinary for a cartoon. It could be a very poor creative decision or an attempt to go against the norm in a bad way.
I have no idea. That's a rather odd and unexpected topic.
Maybe it's just showing affection or trying to clean something.
Well, it could be to draw attention to a dog's curious behavior or to create a lighthearted and amusing image. Sometimes, such cartoons are made just for the sake of creativity and entertainment.
Maybe it sees something interesting outside and is trying to get a better look.
Maybe it's just a funny or random idea the artist had. Could be to make people laugh or catch attention.
Maybe it's attracted by something on the screen or just acting playfully.
It could be for various reasons. Sometimes, such cartoons are made to evoke certain emotions or tell a story in a unconventional way. Or perhaps it's just for pure entertainment without a deep meaning.
Maybe it's just for fun or to show a friendly interaction between the dog and the man.
The word " bootlicker " didn't mean that the other party was a dog. This word referred to those who tried to please others without dignity. There were two main usages. One was to please the other party without dignity or bottom line in a relationship, knowing that the other party did not like them. The other was to describe people who tried to flatter and flatter others without principles or bottom line. It was more of a derogatory description of a behavior and this kind of person, rather than simply calling people dogs.
The reason it's funny could be that it shows the dog's curious or maybe a bit goofy behavior. Also, it might contrast with what we usually expect dogs to do, creating a comical scene.
