She is fit but I like to keep my horses where I can't see their ribs as I run a rescue so im always getting skinny horses so I make sure my horses are well fed

She doesnt look bad to me but it just makes me nervous because they can loose weight fast!! I attached photos of her full body but the only ones I have are undersaddle.. then I attached a photo of my mare... she to fat? I don't think so but others may?
