Flicka is struggling to put on weight, she is always fat as mud and I was scared she was eating too much! But all the sudden she got greasy heal and all her weight fell off and she looked gross with her ribs out, she has a paddock with grass, and gets fed alot to help her put it back on, I've stopped riding her even though her greasy heal is gone after spending $1800 on it and she still is struggling, she gets millrun and chaff, or cool & calm, or relax and she is still struggling. And she is a muscley horse so her muscles are all out, she has put a bit more weight on, her bum is filled in but its been 6 months of feeding her heavery and she should be back to herself, I don't know if she is lacking minerals or got sand in her belly and I know she deffinalty doesnt have worms because the vet tested her.
I need ideas!
