We have shade cloth, fans 24x7 and misters during the hotest part of the day. Also jugs of frozen water for them to lay against. If you look closely under the ramp you can see the fan and a jug of frozen water. You can also see the mist coming from the mister system. They still pant even with all this. But I can tell you that the shade cloth keeps the run 10 degrees cooler.
