Silver Lace, is the chewable tablet for the liver by any chance Denamarin? If so, the chewables must be chewed, but it also comes in a tablet form that does not have to be chewed. It is available on Amazon for a good price, too.
My last yorkie took Denamarin for his liver for years and I could never get him to chew the chewables, so I just ordered the little blue pill. The Tropiclean water additive is also available on Amazon.
