My pup had his last injection on Monday, I was told by the vet that he would be allowed out in 2 weeks last Monday. That means he will be 12 weeks when he is first allowed out? Is this correct, I always thought it was longer but would just like to hear your opinions!
Thank you :-)

Sounds normal to me as this was the age our pup had completed her injections by and was allowed out.

Vets do differ with their opinions on this. with my first It was 4 weeks and with my next it was 2 weeks. My mother-in-law had one of my pups and was told 'because she's so good and healthy she can go out after one week".
Depends on what vet you see, maybe there is a member who is a vet on here that can explain.

I think it depends on the make of vaccine your vet uses.  They will follow the manufacturers guidelines.
