I have my dogs on ff and it works well for them. I add enough water so it covers it when I start a batch.It does fluff up quite a bit. I do not see the bubbles like I do with fermented scratch grain. scratch grain is loose and can take more water. The dog ff smells fermented in 2 days and I feed it out to 6 days. As far as the effects well my shedding machine Lab slowed right down and my Hound has not been dropping her gas bombs all the time. So it may look bad all swollen and wet ( just like one of the dogs lost lunch
) but it works wonders. Our vet is against all dry food because the dog may not get enough liquid and develop kidney problems so this is a good fix, I couldn't stand all the dog food cans! I ferment dog food in the 2 bucket system so there is always liquid in the bottom bucket and I use that liquid to start the next batch.
