Some horses pant naturally. When I first started Misty (a walker) she
would pant, but over the years - she panted less. On very humid days she
will pant but she wouldn't pant as a general rule. Since she is a big girl
16-2 and about 1000 pounds I do everything I can to help her deal with the
heat. I found that by keeping her clipped (even in the summer) she handled
the heat much better and hence didn't need to pant as much.
Morgans tend to grow more hair than Arabs so you might want to see if
clipping will help.
