I spoke to my own vet about this for Marvin and she agreed to do it for me. I know she did speak to OSU about how to administer it, they also sent her the chemo. This was four years ago so maybe they things are different now. I don't understand why they would say to get it off of the website. if it's not easy to find or doesn't really give specifics.
Sending prayers and hugs for Cosmo.
