I tried posting this Fri, hope no one gets duplicates, I do not 
think it went thru....
    Back to the thin hoofs issue, I finally found the article regarding 
a trimming procedure that the author claims will "fix" weak hooves by 
allowing the wall to grow back naturally thicker.  I lost the person 
with the original concern, but the group may be interested in this 
article.
    It is in Equus, June 1995 and is 5 pages long.  If anyone is 
interested either call the mag at 301-977-3900, or to get the video for 
$30. 606-873-5543, or contact me with your fax# or address and I'll 
send a copy.
     In 20 words or less, this 4 point trim puts the hoof back into the 
"wild" state, you leave the horse barefoot for 3 months and they become 
self-maintaining.  Ground forces inform the horn-producting tissues of 
the coronary band and laminae to keep constructing hoof wall according 
to the pattern.  The author claims a tough, shiny, more massive wall 
will have grown well down the hoof in 3 months.
Happy riding!  Kimberly (& Mystery the Morab)
