# 1 is for humans. I tried it yesterday and boy is it ever wonderful.
#2 is sold in beauty shops or beauty supply stores. I also found it in Longs Drug.
#3 is sold in your feed stores or the stores that cater to horses and such. You can google it and then put in your zip code and it will let you know the nearest store to you.
I was the one who would NOT use human shampoos or conditioners on my dogs...........EVER, and now look at me. I gave in and tried the one's that were highly recomended by an expert on Yorkie hair.
