My 40 year old horse was recently (Nov. 7) diagnosed as having Cushings.  His diet is soaked timothy pellets and Hay Stack Special Blend and he is maintaining his weight - but he seems to be experiencing the veil. With the help of Gateway (Su-per products) Freckles' supplements are changing - he is off the usual joint supplements as I was told they are sugar based.  New regime:  Omega Flax powder, GastroShield powder and MSM Ultra Pure powder.  (These are still in the mail)  I was wondering if Chasteberry liquid can/should be given if Freckles is taking 1mg of Prascend daily.  I am still working on vitamins for the Pacific NW conditions.  The person at Gateway said that it is possible that Special Blend feed has everything Freckles needs.  Advice is needed.
