As you can see, she's fully weighting her front feet, which is very good news. I'll probably bring Lily in early this afternoon so Maisie can socialize a bit, and Lily can diet.
Maisie's a bit overweight, which may have contributed to the laminitis. The vet politely said she was "robust", although not obese. In addition to general body condition, there are two spots that for me may indicate that a horse's weight is over the line from well-padded into fat. One is tail-head fat, which is also implicated in insulin resistance (which can predispose a horse to laminitis). Here is Maisie's rump (the dirty side - she rolled!), and if you follow the slope from the highest point down towards the tail, just as you get to the horizon you'll see a slight bulge just before you get to the tail - that's tail-head fat:
Another place I look at in mares is just in front of the udder - an overweight mare will have a distinct "poochy" place just in front of the udder:
So Maisie's on a no-grass diet for now, which will help her weight and make sure the laminitis doesn't flare up again.
