Some dogs can't eat when they see a puddle, and they run up and roll, especially in favour of the puddle. The dog went out on his own, then rolled out a puddle and ended up sleeping in the house without himself cleaning up the mud.
So the dirty body, the master, had to clean it up with a lot of buckets of water, the owner really couldn't find a place to throw it down and wash it, and if it was in the countryside, it would have been in the fish pond, but not in the big city.
With a dog like that, the owner is physically and mentally exhausted, but it's impossible, so let's not drive them back because of this, and it's emotional, even if it's playing dirty, and the owner washes them with tears.
This mud is already done, the master ignores it, and the dog doesn't look at it there, it's supposed to see the owner ignores it, so it's a little upset, and it's afraid of the string, of the wood floor, and then of being beaten by the owner.
It's really greasy for the master to see it, but it's really dirty because it's already done, and if it's still wet, the master certainly won't let it in.
