Re: Dog relearning its name?
The /o/ sound in Modern English is different than the /o/ sound in Hochdeutsch, except for certain dialects of English, such as in Minnesota. In German, the tongue does not move when pronouncing the /o/ or /o:/ sound. In most dialects it does: it's a diphthong, it glides to an "oo" sound at the end.
In England English Received Pronunciation: it goes from a sort of schwa sound to /U/.
In California English, most people place the tongue too far to the front of the mouth, and then glide to a /U/ sound.
Thus in these, as well as most English dialects, the /o(U)/ sound is inappropriate to use in German.
