This is scary stuff, Liz. I have the symptoms hanging on my fridge so that I am always aware of possible trouble. I don't exercise my dogs before or after they eat. I raised (then lowered) their feeding bowls. (Studies can't decide if they should be up or down!) Now the question is whether or not bloat is hereditary. I have heard of a few cases where everything was done right and it still happened. I would think that the DiGel would only work in Phase 1. It has to reach the stomach. It just happens so fast and sometimes by the time you notice, it is already too late. (In the case of the town's K-9). All we can do is watch them carefully, especially the breeds prone to bloat.
