A cartoon character coughing in smoke is hard to process as laughing or poking fun

I don’t get it, like, none of it

Why is the animation like this, and why this is not funny?

That’s a tad bit too specific… Did you choose help out?

The owner choose to put the needlesly violent dog in a position that they would be able to attack someone who would break in.

A dog knows no concept of proportional response, it is responsibility of the owner to know where the dog must be, and go.

That looks to me like way too much harm for keeping private property
