Infectious diseases

Quick answer

UK dogs face several preventable infectious diseases — **parvovirus, distemper, leptospirosis, kennel cough and lungworm** are the most important. Vaccination and year-round parasite prevention protect your dog. Unvaccinated puppies and senior dogs are most vulnerable.

Key takeaways

  • Yes. Parvovirus remains a serious threat, especially to unvaccinated puppies. It causes severe vomiting and diarrhoea and can be fatal within days without intensive veterinary treatment.
  • Through airborne droplets, shared bowls and contact at parks, boarding kennels and grooming salons. Vaccination reduces severity but does not guarantee complete protection.
