I'm assuming you mean part Irish Draught (any horse bred in Ireland is an ISH). The list of approved RIDSH stallions can be found at http://irishdraught.com/ There are also some unapproved stallions such as Flagmounts Freedom as well as some at Acorn Hill. I'm sure there are a few others that aren't coming to mind at the moment.

Thanks, I will take a look, I am specifically looking for a medium built stallion that is over 16.2 with a good easy temperament. Would love a half ISH and half warmblood. The mare herself is a smaller warmblood mare who is very sensitive, I am just thinking about other options rather than going with the typical warmblood crosses.
