Have any of you ever used the Finish Line U-7 gastric aid powder. If so, did it help? One of ours (maybe 2) has developed ulcers from traveling, but the Ulcer-Gard is so expensive. The vet said we needed 16 tubes at $30.00 a tube, just don't have it right now, looking for alternative. She said that a preventive would be just a good, because she didn't believe that the ulcers were real bad at this time. Any ideas? Thanks.
