I didn't used to believe in giving the shots at 6 weeks -- however, Visa's breeder has turned me over. They say that a pup keeps it's mother's immunity until 15-16 weeks -- then why did Visa and her littermates develop parvo at 5 weeks? Something that Marla was told could never happen. Spirit (the mother) was not sick a day in her life, she had been innoculated for parvo the year before and was titred two weeks before conception, showing that she was immune. So how is it that her puppies got parvo at 5 weeks? After that, Marla now gives the puppies parvo and distemper shots at 6 weeks. The vet thought that the puppies that died (not Visa and her siblings that lived) also had distemper (something else Spirit was immune to), as none of them died of parvo -- they died of heart failure and had distemper-like symptoms.

It just makes you think...
