At our shelter we have used transfer factor several times for animals who's immune systems have been compromised which lead to things like mange or severe digestive problems. One dog had mange on his face and around his eyes and this helped to boost his immune system so that he could fight the mites. Another was extremely thin and nothing we could do would put weight on him until we used the transfer factor and cleansed his system. He put on weight and was happily adopted.
