Try that. I found that thread by just doing a search for threads on colostrum.

IMO, Colostrum is an excellent all-around immune booster for both humans and pets. It is virtually side-effect free (unless you or your dog is highly allergic to milk.) It comes in cow colostrum and goat colostrum. I buy mine at vitacost.com, as they have great prices. There are many different brands to choose from. I use Symbiotics.
