What coronaviruses have been identified in racoon dogs?
Here's an abstract for a paper from 2006: https://www.ncbi.nlm.nih.gov/pubmed/16450706


  An RT-nPCR assay was used for testing fecal samples of dogs, foxes, raccoon dogs and minks for the presence of canine coronavirus (CCV). The animals were raised in homes, dog schools or farms... Among 24 raccoon dogs samples, 22 were CCV type II-positive, and from those 16 were additionally type I positive.


Here's another paper from 2003: https://www.ncbi.nlm.nih.gov/pubmed/12958366


  A novel coronavirus (SCoV) is the etiological agent of severe acute respiratory syndrome (SARS)... Evidence of virus infection was also detected in other animals (including a raccoon dog, Nyctereutes procyonoides) and in humans working at the same market.


So at least a couple types of canine coronavirus and other strains closely related (but not identical) to the coronavirus that causes SARS.
