mine pant too, especially my BAs. I think its because they are black, and they get hotter faster in the afternoon sun. My other breeds pant too when its really hot. i would not worry about it. Just be sure to keep the H2O available, and fresh. If you are very concerned about heat, dehydration etc, offer her some watermelon. She wont say no to that! And it has lots of water in it for good hydration, plus it is really refreshing for them on a hot day, nice and cool from the fridge. My girls will eat a chunk of melon to the point the rind is transparent. They love it just as much as we do as a delightful summer treat. I think if shes pooping, eating and drinking, and not showing any other signs of distress (weak, lethargic, losing feathers, gasping, etc) shes just fine. It is mid july...in most places its pretty hot.
