Yep, I didn't call them more intelligent either, just extremely smart.  But I do think there ARE breeds that tend to be "dumb".  There is a reason WBs have the nickname "dumb bloods"Laugh  And my friend that has Hanos would be the first to admit it.

FTR, although Arabs are my breed now I grew up riding TBs mainly.  But have worked with almost every breed out there over the years.
