Ok My Friends,
I'm gonna sound like a used car sales person here.... but ya gotta try Linatone Plus, by Lambert Kay. It is a liquid fatty acid supplement that works wonders! I have been giving it to my Saint for a few days and have already seen an improvement in his coat.
They also have a printable rebate for $3 on their site for those of you who use their puppy pads, vac-away and a few other things. Here's the site. Hope this is helpful!
