I have increased her joint supplement to see if that helps and the vet will be out soon, She wasn't knuckling over at all this morning and I was happy to see that. She is a happy old mare even if she is in pain. She geets me every time I go out and she begs loudly for grain. Its just so sad to see almost nothing left of her former glory. I hope I can keep her pasted together and comfortable for awhile longer. And hopefully I don't have to sell my body to do it.
