There are five main diseases we vaccinate dogs against. These are Distemper, Hepatitis, Parvovirus, Parainfluenza and Bordetella.
Puppies receive an initial course of three vaccinations; one each at 6, 12 and 16 weeks. Puppies on this regime are still at risk of contracting disease until two weeks after their final vaccination hence; full protection has not been achieved until week 18. After this, dogs will require an annual booster for all five diseases for the rest of their lives.
Puppies receive two lots of vaccinations at 6 and 10 weeks of age. Full immunity is attained at 11 weeks of age. A full C5 booster is still done at one year of age however following the first year; the three main diseases, Disptemper, Hepatitis and Parvovirus; only need to be re boosted every three years (rather than every year as with the old regime).
