Compiling all my evidence (I truly have become a pet detective) I have begun to think (and hope, as it seems the lesser of all evils and treatable) it is her teeth. She is at the age to have issues with adult tooth eruption, sharp baby caps, and wolf teeth. In the last few episodes, she is much better after being on Banamine, being pulled from pasture and hay, and fed strictly soft mashes. Any time she has to eat hay or graze and chew and there is no Banamine in her system, she will stamp front and hind feet, shake head, rub nose on legs, run around, stamp more, ears out to side.....and stand there and yawn and chomp her jaw. Never has she tried to roll or lie down during any of this. Her poop is always normal. But~ teeth issues can contribute to colicky issues, as well, as she may not chew her food not properly due to painful teeth, which some of you mentioned.
Thank you for all of your advice, I GREATLY appreciate your ideas and support! I even got an email from one of my Rockin Heart Jewelry customers mentioning a HYPP diagnosed horse at her barn that had been exhibiting colic symptoms. This opened a whole new train of thought and brainstorming. It is through this blog community that we learn so much more about these sometimes complex equines of ours!!
So, I will update you tomorrow night or on Saturday after what happens tomorrow.
Keep the roany pony in your thoughts and prayers!!
