Would a digestive enzyme powder lose its efficacy at all if it sat on the food a while? Specifically, wet food? When the dogs finish one meal, I go ahead and get the next meal ready and throw their meds in with it. So it can sit around for up to 12 hours. I was thinking about buying a digestive enzyme this weekend, but I don't know if it would screw it up at all to sit like that? Not gonna waste my time buying it if it's not gonna work right lol.
