Hi all... adding a few more cents worth, lol... I haven't read all the posts so I hope I'm not repeating what anyone else has already said....
Consider breeder vaccs may be most likely given before 10-12 weeks. The majority of pups still have maternal antibodies in their systems... I think I recall reading that at 12 weeks all maternal ABs are gone from all pups in any given litter. At this point, when the Maternal ABs are gone... the pup will need three of any vaccine (two each a month apart and a yearly booster at one year of age), (except Rabies as it is initially given well after maternal ABs are gone and then is boostered at one year.)
So any vac given before the 12 week mark will need to be repeated twice and boostered at one year, due to the risk of the maternal antibodies destoying any vac given before then. As the pups in any given litter are born at slightly different times, and do not get the same amount of colostrum (first milk from mom) this also causes some pups to lose the Maternal ABs sooner than the other pups in the same litter, so it's difficult to say at which time each individual pup loses the maternal ABs and would thereby benefit from getting a vaccine.
In summary, going beyond 12 weeks with more than two of the same vaccine will not provide more protection and in fact can overload the pup's immune system. |
