OKAY! I hope it is okay to send you guys to this link from another board. A great dane board. But this is either information we all need to know or the biggest crock I have ever heard? I am totally confused by this and since it is parvo related and vaccine related I thought it may be helpful. It knocks everything I have ever heard or learned from vets out of the ball park. I must warn you it is quite long or I would have cross posted it. I hope this doesnt start any arguments. I just wanted some of you breeders, vet techs, vets, pet owners, etc... to give me your advice and or input on this???
