What happened to Dustin the Clydesdale?

I could be late to this, but I noticed on Saturday that Dustin’s name is gone from the stables. I have a feeling that he passed away. It made me a little sad because he’s been my favorite of the Clydesdales since I was a kid (no particular reason). On almost every visit over the past 10-15 years I would stop in at the stables to say hi to Dustin. I’ll definitely miss him if he is gone
