Book a vet visit

Book a vet appointment if you think your dog has this – a vet needs to confirm it and plan the treatment. It is a parasite that dogs can carry after eating rodents or other small prey, and it can also infect people.

What you can do now

  1. Contact your vet
  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. Keep fresh water available
  5. Let your dog rest somewhere calm

Don't

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