What About Prevention of GDV? We strongly recommend you consult your Vet, as well as conduct your own research.  There is a great amount of material on this subject available on the Internet.  Based on our research, it appears to be advisable to feed your dog two or three small portions per day instead one large meal per day.  It also appears wise to keep your dog “calm” after meals for about 30 minutes or so. Be advised that none of these actions guarantees your dog will not develop GDV.  Some experts disagree on the cause (or causes) of GDV.  The height (and effectiveness) of elevated feeding trays for large breed dogs also appears to be in debate.  Some research suggests you should NOT feed from elevated feeding trays.  Again, please consult your Vet. If you own a Great Dane, we strongly recommend you consult with your Vet to discuss a surgical procedure (gastropexy) that may help prevent GDV.  Based on our research, Great Danes are at the highest risk for developing GDV.  In fact, chances of a Great Dane developing GDV is about one in four.
