Has anyone ever gotten "gastropexy" preventative surgery for their Dobermans, or known someone who has??? My vet scared me a little last night describing what "bloat" is in larger dogs. Is this preventative surgery a good/bad idea? Thanks.

Echo within the past 24 hours has had increasingly loose stools, culminating in almost completely liquid bowel movements. He is eating/drinking normally, and his behavior is still happy/energetic. I touched his abdomen in multiple places, and he didn't seem to have any sore/painful areas...
