This story is sketchy so I will simplify. The vet showed up with samples of Meramec--cannot find info on that--I told him not to give it. He heartily recommended Bovishield gold 5 to go with the 7-way vaccine and I was billed for the bovishield and the 7-way. There is no way that those 2 drugs caused the problems that followed 4 days later. I hope this helps. This has not been dropped and it will never be dropped until I am compensated.
