i don't mean one for a particular named horse like a famous race house or for a certain breed of horse but any statue in a average sized city that says basically "thankyou all horses for all you have given to us".

If you literally mean "all horses" the answer is probably NO, but if you accept that some groups are passionate about specific breeds or uses, then non-specific horse statues have been put up The lead page of Marrita http://www.horsesculpture.com/ shows her set of horse bronzes at the American Paint Horse Association and she shows other works she has done. Apparently there are several memorials to police horses or using horses to memorialize police including Omaha and Chicago https://www.google.com/search?q=police+horse+memorial&ie=utf-8&oe=utf-8
