So upsetting to hear this news… but I wanted to share a little something positive, anyway. Hope this is ok.
We have a horse in the lesson barn who was kicked in the pasture and came in with a broken bone in a hind leg. He’s being kept on stall rest and under supervision of our vet and very experienced barn manager, and we’re hoping for a full recovery.
As people come in the barn (and we have dozens of riders in for group lessons each day) many ask - “What’s wrong with Icy?” We explain and tell them that even though his injury is much less severe, he’s kind of like our own Barbaro now. They understand - even though they are mostly inexperienced with horses - that this means a long recovery time, and that he may not recover at all. They ask questions and come back to tell us what they learned while they were at home on the internet. We even have some young riders who have announced that they want to be vets and take care of horses! 
We were talking about this in the barn a few days ago, and our BM said that maybe the most important things Barbaro has done is that his story has educated people and kept them interested. Vet visits for us now bring an audience of riders who want to learn more about what’s going on. They understand that Icy has a long road ahead of him, and that he might not make it. They know more about the challenges of laminitis and infection.
It has been an educational (allthough sad) experience for everyone, and I know that Barbaro’s story has contributed to that. Even if we lose Bobby, his influence will still be felt and appreciated by those who have learned from him and about him, and the horses that benefit from what we have learned.
That being said… Go, Bobby, go! (And Icy too!)
