My 9 year old palomino mare coliced Friday night. Heart rate over 100, pawing stretching her legs out, tried to lay down. Vet came, ultrasound was good, blood work was good, rectal exam she was empty (so concerning with that and heart rate) gave banamine, sedated put the tube down she had no reflux so put her in the stall for the night because after the banamine she wanted to graze (fatty). Saturday at 3 AM she neighed when I walked in the barn, head up ear forward moving around acting fine. Heart rate still seemed high. 7 AM still good vet had me give her two pats of hay soaked in warm water. She ate almost all of it. Vet said Saturday night let her out move around. Put her with her buddy for the night, next morning she's lethargic, head down but still wanting to graze but still a high heart rate. Could this just be colic reoccurring??? She doesn't seem to be in any pain, wants to eat (although rather slowly) but keeping her head down and heart rate in the 90s. Vet had me put her back up now and a half dose of banamine and she will be out later, I'm just confused? She's never coliced before I"ve had her her entire life. Did I do something wrong?
