Hello guys. Been away for a while. Changed jobs and moved to a place that has lots of open space. Issue is that we are midst summer so night time we have temps and humidity as mentioned in the subject. I am walking Rex about 15 minutes or so at a normal walking space. He pants and paces himself. But I get worried. Is there a “heat stroke” danger if at night and walking leisurely? What are the limits there in your experience. Many thanks for your input.
