Like most things to do with pet ownership (other than the law!), it is our, as pet owners, decision what we do with our pets and how we handle situations with them. We have no choice than obey the dog law, but everything else we are free to decide for the best of our dogs.
There was a huge, slightly overwhelming heated discussion/disagreement on another forum that I am on on the same subject.
My dog has had his puppy jabs and boosters when he was a puppy.
I do agree with teprngr however, with the comment that a few hundred years ago, vaccinations were not even possible to have. Nor were many of the things that are here today!
So you can decide on whether or not to carry out injections for your dog(s) and when - I hope people can only lead you in the direction they think is correct and not make you feel like you need to go one way not the other.
Good luck on your decision,
