Why does the cartoon dog pee dust?

The reason could be that the cartoon creator wanted to add an unexpected and attention-grabbing moment. Or perhaps it's related to the dog's health or environment in the cartoon's fictional world.

The reason could be that the cartoon wants to demonstrate the dog's normal behavior or it's a part of a comical moment. Also, it might be a way to show that the dog is in a hurry or uncomfortable and needs to find a place to relieve itself.

Maybe the dog was sick or had some kind of bladder problem.

It could be due to some specific skin conditions or infections that cause the unusual smell. Maybe there are similar chemical compounds released in both cases.

Maybe she drank too much liquid or it's part of a funny or unexpected plot twist.

The snow being too deep for the dog to pee could be due to several reasons. First, the dog might have trouble reaching the ground beneath the snow. Second, the deep snow could make it more challenging for the dog to maintain its balance while trying to relieve itself. And, the cold and wet conditions might make the dog reluctant to go through the effort.

Maybe it's for comical effect or to add some chaos to the story.

It might represent the dog's natural behavior of marking its territory.

It could be that the boy was so engrossed in playing or doing something that he ignored his need to go until it became urgent. Or maybe there just weren't any nearby restrooms available.

I think it's because such cartoons can be used to show different reactions and solutions to a common pet issue. It makes for interesting and sometimes educational content.
