four paws magic coat. I keep some around for the face wash. (Puppy type) 
Durstede.  I really liked this and it did a very good job but i couldn't find it very easliy  
Pet Silk.  still using this i love it and still using it. 
Bless The Beast.   truely loved this product. it dried out Buckeye's hair and made it brittle. I have since decided that i was not diluting it enough. this is the best i have tried so far for matting and smell. he keeps the "pretty smell" for days. and also have found that when i use this shampoo i can go longer between baths. 
I have tried sending an e-mail to the company twice asking what can be the problem with the dryness with no response. 
Coat Handler.  I think I will always keep this around too. I love this one also. It says no brushing needed before bath and it means it. of course mine are always brushed. yeah right! 
Vellus.  I liked this shampoo but it made Ahia and Buckeye both itch. so I didn't even use all of the sample bottle. 
Chris Christiansen.  I like this product also.  
Mane and Tail. this is a good shampoo to keep on hand when I don't have any of the nicer smelling ones. It is cheaper and does a pretty good job.
 Ahia has a silkier type hair. My favorite to use on her so far is-
1. Coat Handler
2. CC
 Buckeye has the cottony type. my favorite to use on him so far is -
1. bless the beast, which i am out of and have been for some time now. 
2. Coat Handler.
Tressie and Archie still have the puppy coats and the CC products looked heavy on them. greasy. might be I didn't dilute it enough for them. 
I have found that , just as human hair, you need to use different products from time to time.  
WOW, did I get too long winded or what?
