Just a reminder that raw trout, like raw salmon, from the Pacific Northwest can harbor a parasite that causes salmon poisoning in dogs, which can be fatal. See http://www.dog-health-guide.org/salmonpoisoningindogs.html for more info.

Raw Trout and salmon from teh Pacific North West does not appear to be a problem for raw fed, healthy dogs, only those that have compromised immune systems. 

This seems to be a fear tactic similar to saying that raw bones are dangerous for our dogs to ingest.
