My dog also will not touch water with a drop of cs in it.  I will try putting 
straight cs down for him as some have recommended.  

I wonder, though, would drinking cs help with his "hot spots" at all?  He is 
always biting himself on the back and scratching.  He does drink a little ACV 
in his water and that keeps the fleas at bay, and that should probably control 
a yeast problem if that is what's causing it... Any ideas on this?  If it's 
allergies, any ideas what would help?  Thanks!
