We feel your pain. My boys are bored. They missed their evening walk last night. I had to carry Max back up the hill on the morning walk, and he overheated at the park the night before. The temp had dropped down to 80 and the sun was setting, but the humidity was too much for him.
We have been playing fetch and running in the house, but the boys grow tired of it pretty quickly.
Doesn't look like we are going to have a walk tonight. It is still 97 degrees.
