These two novellas are on the Locus list and available online:

The Work of Wolves, Tegan Moore. A search-and-rescue dog with enhanced intelligence. Interesting and sometimes trope-subversive POV.

Waterlines, Suzanne Palmer. An administrator on an ice planet deals with unexpected contact with the local aliens. Man, Palmer can tell a story.

(I am now up to having read 12 of the 32 Locus list novellas and am also partway into a 13th... and there are still more I'd like to read eventually... the world is so full of novellas now, I love it...)
