I am so grateful to everyone who has posted a reply! This was my first post on the forum and the information I'm given was such a help. Forgive me for not knowing how to tag everyone who contributed to personally say "thank you!" We've had a salt block out ever since it's started turning warm and I actually added another water source so she wouldn't have to go very far if thirsty. The frozen jugs are a great idea! Going to try that tomorrow..not much bothers her she will probably want to play around with them ! I'm thinking I will get the vet to do a blood draw just to check things out not really knowing her history...and it's always a good idea to have a baseline right? Knowing others have some horses that sweat and some that don't really puts my mind at ease. Thanks again for all the help y'all! (I can't believe it gets that hot in Iowa or Missouri!) ?
