Ive read its very effective for RR's to do with dermoid sinus. For me the main aim is to do with prevention of cleft palates/hare lips and (unproven or researched as far as I know) HV in my breed. Although the why's/how's of HV occuring are still being looked into, and my stock is xrayed for it, the use of folic acid cant hurt.
Ive been advised to use folic acid in my breed and wether it really does make a difference or not, it doesnt hurt to try!
