Be very careful about adding water to some kibbles. Many of them (including Raw Instinct) are preserved with citric acid and foods containing citric acid should NEVER be soaked. I don't think Evo is at the moment, but thought I would mention it in case anyone feeds a food that is preserved with citric acid.
When any dry fod with citric acid is soaked it increases the chances of bloat 320%, especially with older dogs. There is also elevated risk if you feed these kibbles with canned or raw for the same reasons.
Here is the study if anyone is interested: http://www.vet.purdue.edu/epi/dietrisk.htm
Keep checking your kibble too...Raw Instinct never used to use citric acid as a preservative but they suddenly changed. Geez, one more reason to just feed raw :angel:
Yes, it is to prevent bloat, but according like FallRiver mentioned, it turns out it actually increases bloat in foods that are preserved with citric acid. So it can be helpful, but it can also be detrimental depending on the ingredients of the food.
