Recent research has shown that the heat dissipation through panting is
higher than once thought and that panting plays an important roll in heat
dissipation under humid conditions (even in cool temperatures) - where
evaporative cooling is severly compromised.
As far as particular breeds, I have seen horses from all breeds (including
pure Arabians) that pant. Jon Warren, DVM, a well respected endruance
vet, said one time that in hot and humid conditions he worries more about
the horses that don't pant those that do.
