Just now saw this thread. Clearly the mare is looking noticably better, good for you! I would suggest being pretty cautious about how long she has access to the kind of rich green grass I saw in the photo of her 'grazing in the yard',I think it was? Rich green spring grass can be a real risk factor for laminitis/founder for about ANY horse; be sure to limit her time on it, AND only very gradually increase that time. in the photo of her wearing the saddle, it appears the saddle may be 'too wide' in the gullet for her,at least for now....looks a lot like the underside of the swells is about 'resting on' her withers ,even w/ no one in the saddle. Once she gains more, filling in more over her back, it 'might' be better...or maybe with a thicker saddle pad(though increasing the thickness of a pad is not a 'fix-all' for saddle fit, either.) Anyway, you have been doing an admirable job with her,and I hope you can look forward to many years of enjoyment of her!
