ALL dogs are susceptible to bloat. There are many theories floated and which run rampant and get passed along like the one about deep-chested breeds being more susceptible as well as the one about it coming from heavy-duty playing after meals and "inhaling" food along with lots of air. (Reminds me of that old warning to kids never to go swimming for at least an hour after eating or you'll get cramps and drown.) Some say to feed 2 or 3 small meals a day vs. 1 large meal. The fact is, NO ONE KNOWS what actually causes bloat. There are only theories. So while it is a medical emergency when it happens, you can't worry yourself to death over the rumors you hear that might (or might not) cause it. That's like worrying about whether or not your dog will get cancer or have a heart attack. Best advice is to keep an eye on your pooches and notice if they appear to be in distress, and get them competent care right away if they are. If you do decide to make changes in their feeding habits, for instance to have them both on the same meal schedule, I would recommend doing it gradually and not abruptly. Other than that, enjoy your new family member and don't stress out over the rumors that will only make you crazy! Remember, the cause of bloat is UNKNOWN.
