I let the keifer go to cheese which is mixed to taste with Himalayan 
salt,Potassium chloride mix.
This I got my daughter using and recently her 9+ month old pure-bred German 
short-hair ate some poison mushrooms.She was wasting 
away,vomitting,diarrhea,weight loss,skin and bones,etc.,.I told my daughter to 
give her the whey from the Keifer.It was amazing how fast the dog recovered and 
about 3 weeks later took a top prize at the big dog show for her age group.The 
dog gulped it down like it was candy,so she now gets some Keifer cheese too.
Also she gets a light dusting of Sulfur crystals on her food  which she avidly 
devours,strange, considering how bitter they are.
