Have a small 5 yr old mare that does not feel 100%. She will do the stretch stance, she will be laying down to eat on occasion, BUT, she eats well, drinks well, stool looks normal, no sand in system, have given mineral oil, she is in good body weight, this has existed for about 4 days. These symptoms always concern me that the mare is aborting (if bred), but if she was, the fetus should have been expelled by now, I think.I have not had experience with ulcers (had mini's for 20 yrs) could this be ulcers? Your thoughts will be appreciated.
