This is a veterinary concern â distemper vaccination in dogs needs to be administered by a vet. For the dogs with no symptoms yet, prompt vaccination (even post-exposure) may help reduce severity. The dog showing 'chewing gum fits' (jaw myoclonus) is showing classic distemper neurological signs â this is a bad prognostic sign.
Next Steps
Contact a veterinarian or animal rescue organisation immediately. Vaccinate the asymptomatic dogs urgently. The dog with seizures needs urgent vet care â neurological distemper is often untreatable. Contact a local animal NGO like PETA India or Friendicoes for rapid vet assistance. Consult me on Practo for any human health queries.
