It's not the salmon per se, it's a microscopic 'fluke' that is hosted in a freshwater snail in the PNW. Any anadromous fish can host the fluke, and the bacteria in the fluke, and dogs being dogs, an otter carcass, or fish duck, or heron poop, can infect your dog. Watch for distemper type symptoms with diarrhea...get the dog to the vet or get some ringers lactate and a needle from vet supply...quick. Dehydration...It is more often than not fatal.
