Poor baby Hannah! Bloat just scares the heck out me! It would seem strange that she would just suddenly start having a bad reaction to her food??? Is she eating at the same time in the PM., and the same amts.?? Does this happen after her AM feeding? My vet is always cautioning me on not feeding the girls large amts at one time, as both are "wolfers." And especially, no real strenuous exercise after, but also BEFORE eating!! (About 1 hr.) Has she been into anything strange lately, maybe out in the yard?? Table scraps?? Rawhides or chew bones? That's all I can think of at the moment! I would probably give the vet a call. And I would probably start off by offering her smaller amts. of her meal at a time; that is divide each meal into maybe 2 or 3 portions, 10 or so minutes apart; if that's possible. Sorry I don't any true medical advice to offer. Me, I ALWAYS head for the phone!! Hope Hannah is better, poor pupster. Lots of love and tummy rubs to you Hannah girl, from Sandra, Star and Cody!
