Hi there, The distemper vaccine that ferrets get is not the same one that dogs get. The ferret vac. only contains protection against distemper while the dog one is DHLPP which stands for Distemper, Hepatitus, Leptospirosis, Parainfluenza, and (I believe) Parvovirus. The ferret vaccine that we use at the hospital I work at has a label with Fervac. It is in a different bottle and is a different color than the dog one. Actually Fervac-D is the only USDA approved distemper vaccine for ferrets. At the clinic I've been working at for a while, we charge around $25.00 for the vaccine give or take a few dollars. Here is a link for you to read a little bit about it. http://www.ferret-universe.com/health/distemper.html#fervac. I hope this helps. ~Rachel~ [Posted in FML issue 3508]
