I'm so sorry to hear that! Please get him in to see a vet. Your vet will probably recommend a chest X-ray to get a better idea of what is going on. In a 9 year old chihuahua some possible causes include heart failure, pneumonia, or cancer. If he seems labored in his breathing, do not delay, please take him to the vet right away.
