Animal healthcare pharmaceutical companies go out of their way to create and maintain a positive image. They want to look trustworthy, right? Why would you trust the health of your pets or livestock to inferior products? The other night I was at a sports bar, and this advertisement for Protexin was playing on one of the televisions in the background. I couldn't help but notice a spelling error in it. Watch it through, and you'll see what I'm talking about. What on earth is a "digestive track?"
