MyFairLacy, this is sort of off topic but I have a question for you. Could you explain why Texas A&M recommends giving DHPP at 6, 9, 12 and 16 weeks? From what I have read, dogs only NEED two sets of puppy shots. Those would be at about 12 and 16 weeks when no maternal antibiodies are interfering. To be safe they are given three times (8, 12 and 16 weeks). Maternal antibiodies are likely to counteract the 8 week shot but I hear nobody really knows and all animals are different, so why does Texad A&M give them four times (when three is plenty) and why do they start at 6 weeks (when maternal antibiotics are sure to counteract it). I don't want you to have to defend it. I am really interested in their reasoning. Thank you
