Thought I would share this with you guys as it might help lessens someone elses fear if confronted with it! Max is on box rest and when I saw the size of his sheath I freaked out
After speaking to the vet he assured me is quite normal and very common in horses on box rest - wish they had fore-warned me of box rest side effects
Anyhow, with some Danilon and more walking in hand it soon went back down to normal size
