Gagging is a throat reflex. Dogs usually open their mouth widely and make a retching sound. If it is brief, it is usually not a cause for concern. Older dogs may gag more often due to underlying health issues.

Gagging in dogs can be mistaken as a cough or vomiting. Gagging or retching sounds like they are trying to vomit while also coughing. Sometimes they bring up white foam or mucous. If it persists or is accompanied by other signs contact a vet.

Is your dog gagging, coughing or trying to be sick?

  • Gagging: Gagging is a throat reflex. Dogs usually open their mouth wide and make a retching sort of sound. Gagging usually happens just before or after a cough. Sometimes they bring up white foam or mucous.

  • Coughing: Coughing is often identified as a hacking sound as if your dog is trying to get something out of their throat or mouth. It doesn't bring anything out and if it does, it's quickly swallowed.

  • Vomiting: Vomiting is rather obvious as food or stomach contents will come out on the floor.

If you are unsure we recommend you take a video of your dog and show it to a vet.
