Some of the slow weight loss is just due to the nature of the beast, so to speak. I'm going to assume from the look of her that she is a shetland or shetland cross. They are naturally a little stocky and notoriously easy keepers. It's best not to pull the excess weight off of her too quickly - it might not be best for her health. You also need to be sure that she gets the nutrients she needs while you have her on her "diet." :)
