My dog has been coughing and sneezing so I took him to the vet and they did an X-ray. They said his lungs are clear but that his heart looks a little enlarged. He was put on antibiotics and I was advised that if the cough doesn't clear, to go get him an EKG at an animal hospital. Now I'm worried sick about my dog having some kind of heart issue. Does anyone here have any experience with this? Has it been something you and your dog have gone through? I'm hoping and praying that her cough goes away! 🙏
