Of dingleberries and aarschgnoddle

From Bryson, we learn that the Pennsylvania Dutch have "curiously specific terms" in their dialect of German. One such world is aarschgnoddle:

the globules of dung found on the hair in the vicinity of the anus (and, no, I cannot think why they might need such a word)

One shouldn't have to think hard, as English has its own word: dingleberrry. According to Wikipedia (yes, there is an entry; take that Encyclopedia Brittanica):

A dingleberry is fecal matter stuck in small round clumps to the hair or fur around the anus. It is often found on sheep that have not been shorn for some time and in some other long-haired animals, such as persian cats...The term is popular in both Australia and in rural America, especially the South. The term originates from the now somewhat-antiquated name for the Southern Mountain Cranberry (Vaccinium erythrocarpum).

UPDATE: The OED (of course) has something to add:

His presentation ‘left a lot of dingleberries’ means he splattered thoughts and inferences all around the main task.

Looking at dingle, perhaps there is something to the supposed connection:

[Of uncertain origin. A single example meaning ‘deep hollow, abyss’ is known in 13th c.; otherwise, the word appears to have been only in dialectal use till the 17th c., when it began to appear in literature. In the same sense dimble is known from the 16th c. Dimble and dingle might be phonetic doublets: cf. cramble and crangle.]

A deep dell or hollow; now usually applied (app. after Milton) to one that is closely wooded or shaded with trees; but, according to Ray and in mod. Yorkshire dialect, the name of a deep narrow cleft between hills.
