I paid £99 for jabs for life due my pup.
My vet said the third jab was optional as it for a new strain of lepto but as he is a ratter he must have it (makes sense).
Also, this is a chain of vets, they gave me a credit card type card to prove I'd paid for jabs for life. If I had a more than one dog I could drive to the next nearest vet and get the other dog done there under the same name... but obviously that's very dishonest... lol
