I was recently told that dogs that are "high-chested" are at risk of having their stomach going into their chest and twisting after they have vomited, resulting in death. I have a chihuauha and was told it was a high-chested breed. Is this true? Should I be concerned about this? I've done some research on the subject and have come up empty handed. If this isn't true. Then is there any instance that this twisting of the stomach can possibly happen? Thank you!
