After reading TnKen's post about losing his dog to heat stroke (Gone too Soon), I went back and re-read the post on cooling, but one thing missing from that post was any information on what to look for that would indicate that your dog is beginning to suffer from heat distress. Where I live it is currently about 85 by 7:30 or so in the morn and is hitting 98-102 nearly every afternoon. I try to do about a 5 mile workout four or five days a week and usually take the dog with me. In this hot weather, I make him stay with me and not just run around and my pace is only about a 13 minute mile so he is at a fast walk or slow trot but I do worry a bit about him overheating. Usually somewhere around the 3 or 4 mile mark I will stop and hose him down for a few minutes and then we slow down for the last mile and he usually gets hosed again but I am a bit concerned about hurting him. Anyway it would be nice to have a good discussion on what to watch out for and some idea of what a dog should reasonably be able to stand.
