New pups and older dogs - vaccinations

[NaturalBlondeYeahRight]

I've had a little look on here and good old google but have had conflicting results. DP have new pup, first injection tomorrow. When can my fully vac dog meet it?
This has made me think, we are considering a new pup. How does this work for jabs? Should a good pup come with first one/is the risk small if you know your dog is healthy/should I try to keep contact to minimum?
This must be a regular issue yet I have no idea.

Straight away.

Your unvaccinated puppy can mix with any vaccinated dog.

what daisy said.

Ah, thanks for that. That was my first conclusion but Bil was worried that even vaccinated dogs can be carriers (is this true but risk minimal) But then how could you ever get a pup?

My first line should have said Dparents, not DP. The pup doesn't live with us.
