He seems to be doing better. Just gave him his bedtime meds and he was less uncomfortable than he was right before his last round of meds. Felt good enough to ask for scratches at least. He is still shifting his weight a lot though. I’ve got an absurd amount of shavings under him. Normally I use pellets but I went and got him some of the big fluffy flakes. Horse approves of both the shavings and his soaked hay.
