please remember about the second layer of this poem – it’s not only a matter of a dog – it is also the fog, something, what is disturbing, what does not allow us to see things they are. So, I’m not so sure, if the person in the poem is walking alone, or maybe with the dog – the person just tells us how does it look like :)
I was understand: if the fog is low, person’s walk with dog (but dog is under visual coverage of the person:
somewhere in the fog, that: no dog).
I’ve a look: realy low fog, that head of walker is up the top of fog’s coat.
Effect: surely with, but without.
Gosiu! Czy to takie, proste znaczenie “low” zastosowałaś ?
