It's a really lovely little pony, pleasure on the ground and ridden, used for RDA and for riding school as well as doing a bit more like jumping with her owner. One of those amazing ponies that is very quiet and straightforwards for very tiny riders like my DD but is happy to do more with a competent rider too.
This morning there were several short moments when groomed, ridden (obviously stopped riding when it was apparent something not quite right) and in hand when she seemed quite worried, scooting forwards a little, tail swishing, swinging quarters round different directions and kicking. Just like horses often do when a horse fly or something is biting or zooming about, but there were none there. Checked back, feet, tail, legs, tack, no signs of colic, trotted up sound and not sensitive to touch anywhere except maybe tail area, but possibly coincidence.
Kept an eye on over the day and all seems ok now - just wondering what it could be? Very out of character and the poor pony was obviously trying to be polite but was clearly bothered by something on several occasions over a period of about 15 minutes. Hopefully just a momentary discomfort that won't happen again and will be none the wiser but can't think what to check for if it ever happens again. Have had horses most of my life but usually have some idea what's up if they aren't themselves whereas had no idea how to help this time!
