My golden retriever, Roxanne, started gagging uncontrollably. I took her to an emergency vet and they thought she got a bitter poison in her mouth. She hasn't been around it at all and they said her gagging should stop. The gagging did not stop and her frantically eating grass was worrisome so we took her to a different vet. She had surgery 1 week later to remove stomach blockage. All they found were items that she should have been able to pass (grass, leaves, and other small things). She has been healing very well. However, she is still straining to go to the bathroom and when she does, its small and watery. She is acting like something is stuck still. I'm worried because she hasn't been able to go to the bathroom for two days now and the vet does not know what is wrong with her. Has anyone encountered this problem or have any idea what it could be? Could they have missed something that may be in her intestines?
