Book a vet visit

This is not usually an emergency on its own – contact your vet if it lasts, gets worse or your dog seems unwell in any other way. It is nearly always harmless and often happens because something irritates the back of your dog's throat.

What you can do now

  1. Contact your vet if you are concerned.
  2. Note when it started, how often it happens and what else you see.
  3. Take a photo or short video to show the vet.
  4. Let your dog rest somewhere calm.

Don't

  • Do not give any human medicine.
  • Do not wait if it gets worse.
