Border Collies can work when it's quite warm out. They need breaks and it's pretty foolhardy to work any dog in temps when it's dangerous for people, too, but many work on farms where there's no choice but to get all the work done when it's already in the nineties with high humidity (like on my friend's cattle farm).
BCs may also be prone to EIC. They are looking into it - it's only popped up now that most of the breed is in a "weekend warrior" sort of lifestyle. It is, as someone said, not heat related, however. It seems to happen with really tightly wound dogs in high pressure situations. Sports training ups the training pressure constantly, so it's most commonly seen there.
I had a young female with it, but she "outgrew" it when she settled down to the workin routine. It was a constant danger though, any time we got into a tough situation.
