  Not sure if this applies to the question posted, but several 
dressage books and articals I have read said that foaming at the
mouth is a GOOD thing, and is caused by stimulation of the
parotid (?) glands due to neck flexation: having poll flexed 
stimulates the glands, causing salivation.  It is thought to keep
the mouth moist and responsive.   

Does not seem like anything to worry about.
