What's the
evidence that alfalfa "causes" bloat in dogs? Evidence is a well-designed research study...not a blog post. Let's take a look and see what's there, if you can post a paper that got you thinking about this.
My understanding is the state of actual
research on canine bloat is not yet able to determine causation. Any "Internet guru" posting that X is a "cause" of bloat probably either isn't following the research -- or else doesn't understand the difference between causation and statistical correlation. All the actual researchers have right now are some correlations (some of which are quite surprising and the opposite of Internet mythology about bloat that masquerades as certainty). (Anyone who has trouble separating correlation from causation ought to check out a copy of Levitt & Dubner's classic book
Freakonomics from your local library (or download the audiobook) -- it's a magnificent, entertaining book for non-math people that is incredibly helpful.)
Moistening food that contains citric acid correlated to a 320% INCREASE in bloat risk. So...I would rethink that strategy, at least until more is known about causation.
I don't remember seeing any correlation with alfalfa as a food ingredient in that. There were some other ingredient concerns though (like fat high up in the ingredient list).
Here is the summary of a few different studies, with links to the studies (as I think it's important to read primary sources yourself, if you're worried about bloat):
