Unless you know of this being a hereditary issue within Bernies lines (imo) he is not a dog at great risk for bloat. Let him be a dog, do what you want with him and when he's thirsty Let him drink. I know of more dogs who bloated in the middle of the night, or while owners were at work...Then After drinking water or eating. You can try to prevent it, but typically if its going to happen~It Will.
