What is the difference between Lepto 2 and Lepto 4?

Lepto 2 provides protection against two strains and Lepto 4 provides protection against four strains. For those dogs who like to go into ponds and streams and who drink out of puddle water in woodlands or visit farms, we highly recommend the Lepto 4 vaccine to provide the most protection available.

Should my dog have Lepto 4?

Should my puppy have L2 or L4?

Dogs that don't travel outside the local area should currently be adequately protected with L2, whilst those who travel to Europe and certain regions of the UK will be better protected with L4.

Can you mix Lepto 2 and Lepto 4?

Although the L4 vaccine probably does work effectively to booster the L2 vaccine, this is not licensed. If we give an L4 vaccine to a dog that has always had L2, at best the dog will be protected only against L2 and thus would not be considered fully vaccinated.
