Abscesses are quite common, there's a lot going on in a laminitic foot.
I agree on the lifelong commitment. But it's not so bad as long as you have control over the management. I have all mine on the same diet now, the non- laminitic get something extra in their bowl, since it's easier to add than to take away lol.
I keep thinking back, 15, 20 years. A laminitic horse was a rarity. And now they seem to pop up all over the place. Why? What did I do different then? Nobody knew about NSC and IR. My horses lived in a drylot, went on pasture during the day, ate grasshay with lots of different species of grass and herbs, and grain, as needed. Never ever a founder episode, and none of them were underweight. So what happened, what is different?????
Don't recall any with symptoms of ir or cushings either.
We fed lots of grain, usually a gallon at a time and sticky sweet. No founder, no wld.
Now I don't dare even give my two grain, I, too, wonder what happened.
