Dealing with girthy horses/ponies

[Qualconcep@aol.com]

Just curious as to how others have dealt with a girthiness problem that 
either developed or was inherited.  I am considering a pony for my daughter 
and the only vice the little guy has is that he is girthy...enough so that at 
7, she is too young/small to deal with it.  The owner says she goes slow, 
keeps the chaos down to a dull roar, and feeds him carrots when he is still.  
All well and good, but does someone know how to eventually get rid of this 
behavior?  The pony is a 13 yr. old Shetland and is otherwise well trained.  
Thanks a lot.
