My mom has seen this email on four of the dog related email lists she is on in the past week.
A very similar press release was issued in February of 2008 by Oklahoma State University's Center for Veterinary Science. What a coincidence, this veterinary center claimed to have been the first to discover this vaccine (even though it has been known for 8 years) and developed a vaccine for it...even though the current parvo vaccines on the market already protect against this known strain of 2c. The press release was full of scary statements, such as about a "breeder" who lost 600 puppies in one night. Um - the ONLY type of place that has 600 puppies at once is a HUGE puppymill operation, and I'm not surprised that a puppymill operation would have a parvo outbreak, since puppymill operations are known for cutting costs by providing poor living conditions and vet care.

Trust me puppies - you do NOT need to rush out and get another vaccine!
