Vaccines for cats and dogs: the basics

Which diseases vaccines prevent, when puppies and kittens should start, and why rescued animals need them.

Vaccines are one of the cheapest and most effective ways to protect animals — and, in the case of rabies, people too. Rescued animals often have no vaccination history, so a vet check is the first step.

Core vaccines for dogs

  • Parvovirus — severe bloody diarrhoea; often fatal in puppies.
  • Distemper — affects lungs, gut and brain.
  • Adenovirus (hepatitis)
  • Rabies — fatal, and transmissible to people. Required by law in many countries.

Core vaccines for cats

  • Panleukopenia (feline parvovirus) — very contagious and often fatal in kittens.
  • Feline herpesvirus and calicivirus — "cat flu".
  • Rabies where required.

When to vaccinate

Puppies and kittens usually start at 6–8 weeks, with boosters every 3–4 weeks until about 16 weeks old, then a booster after one year. Adult animals with unknown history start with a first dose and a booster. Your vet will recommend the right schedule for your area.

Until fully vaccinatedKeep puppies and kittens away from unknown animals and places where many dogs go, and wash your hands after handling street animals.

Vaccines are a key part of our rescue costs. Sponsoring veterinary care pays for vaccines, deworming and check-ups for rescued animals.
