@tsarstepan,
Oh, damn, he said "dag" not "dog".
Dag means a bit of wool dangling round a sheep's bum, which has become noisome and hardened with pooh and wee here....or a person with no finesse or taste.
However...there IS a cat related meaning:
Dag
When you have a really old cat and he/she has lost the ability to excrete properly, and they do a poo but still has a dag (a bit of poo) hanging on.
"Hey, look, Whiskas has a dag!"
"Ewww"
Miranda DOES have that problem sometimes...but it's because she eats entire long blades of grass...which join the turds together in one awful choo choo train, and sometimes one doesn't want to come out!
THAT does lead to extra shenanigans, but it's an occasional thing!
But it's not just a Miranda thing, you know!
