Today's words

dhole /ˈdōl/ - a wild dog (Cuon alpinus) occurring from India to southern Siberia that typically hunts in packs and often preys on large animals (such as deer and antelope)

vitrify /ˈvi-trə-ˌfī/ - to convert into glass or a glassy substance by heat and fusion; to become vitrified

Both words courtesy of the Dictionary Devil, from separate puzzles. I expected the second to be related to vitriol, and it clearly is, but not in the sense I was thinking of.
