So I have a 25 year old appendix quarter horse. Today when I was feeding him I saw that he was kind of "off" only someone who knows him would see why. He is usually VERY pushy around food and nickers whenever he sees someone. He did neither when I was around him. So I checked his feet (he has foundered before) and only his front left was hot (?) so I thought, oh great he has founder. But then he stretched himself out and went to the bathroom (number 1) and just stood there after he had gone all stretched out. Then 5 minutes later after getting the other horse fed, he went to the bathroom again (after walking around for a little). What worries me is that he hasn't touched his water all day long (we have around 2 inches of ice and no foot prints leading to water without shoes on them as he is barefoot while our other has shoes) his stall was COVERED in pee but no poo that I could see. Any ideas on what could be causing this? Is peeing quite frequently a sign of founder or colic or something kidney wise? Whenever I go out I seem him pee (which always seemed odd to me) but I have never seen him go more than once within 5 minutes. Sorry for the long post.
