Can you give me more details on "shield"? Is it a food? How do you administer this? How often? How long does it last for? etc.
Same for Vital please.
Do these two products overlap? Meaning, can I get by with just one? If so which one? It seems that BW has lots of products. I can't see someone using all of these at once since there has to be some type of overlap or they have to have something that's "all purpose" which kills a few birds with one stone.
