My dog is gagging and throwing up clear mucus. What's wrong?

Updated On September 23rd, 2025

my dog has been gagging and vomiting this whole afternoon. Every few minutes she starts to gag and then vomits out a sticky whitish/clear substance and no food or anything. Can it be because she ate something wrong or something minor. I'm scared that she is poisoned although there is nowhere where she could eat poison that I know.

This could be a sign of an upper respiratory infection such as kennel cough or it could indeed be a gastrointestinal problem. Kennel cough often present as gagging and mucoid discharge. Kennel cough is self limiting and usually goes away by itself within a few weeks and often does not need treatment. Should your dog have a fever or the coughing/gagging get worse or should your dog get lethargic, you need to take her to your veterinarian for an exam. Should your dog indeed vomit, you can try the following: I would fast her for 24 hours and then put her on bland food for two days, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to regular food slowly over a few days. If this does not clear up the vomiting, or if the vomiting increases, or if your dog gets lethargic, she needs to see a veterinarian for an exam as there may be something more serious such as an infection going on.
