i read several months ago ( i think it was in the Whole Dog Journal) about a product called Willard Water. the WDJ raved about it, and generally i trust their opinions about most things. has anyone out there used this product for their labs, and what kind of results have you had ? like i said , i trust the opinion of WDJ but i have been around long enough to realize their could be some 'hype' factor associated with this product too. thanks !
