I've been following your conversation about feeding raw salmon to dogs. When we moved to Alaska years ago, I learned that what my father told me was true....that Alaskans feed raw salmon to their dogs and the dogs thrive on it and do not get sick. I found that to be amazing as we suffered the tragic loss of a golden retriever when we lived in the Northwest. My husband and a friend were cleaning salmon in our driveway and somehow, one of our beloved golden retrievers got ahold of either a small piece or perhaps licked up some blood.
She became very sick and our vet was the one who figured out what was wrong with her...that she had eaten some raw salmon. The parasites in raw salmon laid eggs (fluke eggs) in her internal organ (liver?). Well, in spite of the best medical care in the doggy hospital, she died.
When I asked our vet why it is that dogs in Alaska do not get sick, he thought that perhaps it is because the dogs are fed salmon from the time they are pups and they could develop an immunity of sorts to the parasites. Or, that our salmon up here does not have these parasites.
I'll have to go read up on the links you posted, HairOfTheDog.
It's either an immunity or it's not present in AK salmon, I'm as curious as you are.
