I do! Two of them! I am in Northern california and it is pretty hot this week. 95 today. Tonight I noticed both my pastured horses were sweaty on their necks a little ahead the withers and back some. Pretty sweaty too. My fatty was of course more wet, you could see the run pattern down toward leg, especially on the right side. But both were wet for sure. I just found it funny that they had identical sweat patterns. Ugh I hate summer! Supposed to be in the hundreds by the weekend.
