wex the pup will be fine mate at 6 weeks , but jabbing them so early is a waste of time as they still have the mother imunity and just piss out the vaccine much better to do it at 8 week or better still 10 weeks, with our pup we do them at 10 weeks but they run around with the rest of the dogs all 15 of them and we have never had any problems , at langford vet school they are doing reseach into this and so far there saying 10--12 weeks it will be interesting to see what final answer they come up with by the way the greyhounds at langford are not vaccinated untill there 14 weeks old !!!!!!!
