I just can't stop saying thank you enough to all the responses and the wonderful outpouring of support I've gotten here, in emails, calls, etc. I really appreciate the help sorting through this especially since it's so hard emotionally and sometimes I don't think I'm thinking clearly about it.
I'm very surprised but pleased to say that Cappy is still with me at this time. I honestly didn't expect she would be and don't know that she still will be tomorrow, but right now she is and that's a good thing...as long as she's not suffering and when I think she's gotten to that point I will make the decision that needs making.
She still has little to no appetite but even one tablespoon of feed every couple of hours is better than nothing at all. She is currently on gastrogard and banamine and had one steroid shot yesterday also. It could be my imagination or wishful thinking but about an hour after her meds she seems a tad perkier. But by nighttime she is usually back down and pretty lethargic. Giving her shots when there is just no meat on her bones just breaks my heart. But she's so calm and sweet and has ALWAYS put up with vet stuff without ever fussing. When she aborted and was flushed and examined and had blood drawn, once it was all over the vet commented "we didn't even put a halter on this mare, did we?" Nope, I just stood next to her with my hand on her neck and she stood there the whole time!
I've ordered some other things I'm going to try to help her. I'm taking advice from several different sources and trying to merge it all and come up with a plan. Some of the things I've got coming and will try alone or in conjunction with each other are:
Prednisolone
Dexamethasone
Stomach Soother
APF
Yogurt
Safflower oil
ADR paste
alfalfa meal (this is different stuff. take a look at it sometime if your feed store has it)
I will be working out the dosages and frequencies as I go. I am NOT suggesting that anyone else try this approach (everything but the kitchen sink) but I figure I have nothing to lose and everything to gain. This is what I am choosing to do and I'm sharing it so maybe someone else can learn, not for any other purpose. If I can just get her to eat, with her spirit she may be strong enough to get paste this low point. Regardless, I do believe the vet is correct and that there is something life-ending going on inside her, I just don't know if it's meant to be right now. If it is, then I will accept that. But if she seems to want to keep trying I am going to try and help her.
Thank you all again.
