I just made a vet appointment in a couple of days but I am curious as to what you all think might be going on with hubby's mare. We have owned this mare for about four years now, she is 10 this year. She is an excellent trail mount, very forward moving, alert, willing, and soft. She runs around the pasture bucking and kicking, eating and drinking fine etc. This spring for her first handful of rides she was good as usual. She has always been a tad "irritable" when tacking up. Her saddle(same saddle since we got her)fits good and we checked her for any soreness etc, found nothing. We checked the saddle as well, nothing. She is now wanting to kick out when cinching(she is cinched slowly.) She also is starting to stop periodically while on trail to urinate more than normal. Sometimes she relieves herself fully but more than not hardly anything comes out if at all. It is like she is in "heat" but she isn't. She is starting to refuse descending even small hills and ascending them as well. She moves more tense lately. She does not act like she is sore in any limbs, it seems like it is internal pain. I was thinking bladder, maybe a cyst or tumor, kidneys....She was bucking and running around the pasture yesterday like nothing is wrong....frustrating. She has stopped to "urinate" on trail, I kid you not at least 5 times within twenty minutes when we were riding over the holiday weekend.
