horse with dislocated shoulder con't

[Lkswalkers@aol.com]

I don't think the shoulder is dislocated, the leg is in same alignment with 
other leg. It was dislocated 3mos. ago A lot of swelling noted All I know is 
to hydro it to help with swelling, any help or ideals will be appreciated. 
All they want it for is just a pet, so there will be no ridding.
