My dog can not take a full breath. It appears her lungs won't allow her to breath full after exercising. She drools in an unusual way. And when she is trying to breath hard after exercise it's as if she has the hicups. What's wrong with her?
I can not make a diagnosis over the internet. I recommend that you bring your pet to the vet for a check-up. It is possible that your pet has a heart condition or a respiratory condition. I would not worry about hiccups. vetcare
