Preparing Harley this afternoon for his trip tomorrow, we were standing at the wash rack, he was getting a bath, I was getting sprayed. :) I found his sheath swollen, and still some chest swelling - almost saggy. Weird, and kind of yucky.
Talked to Dr. Sam again. This time, it's dexamethasone shots. One tonight, one tomorrow afternoon. He believes it's still fire ant inflammation, and gravity causing all of it to "fall low". This should explain why the things are swollen that are.
Harley's attitude is fantastic. He's eating, drinking, pooping, peeing, snuggling, and grazing. He seems unbothered by the whole thing now that he's not itchy all over.
Time for me to go google this new medicine, and see what I can learn today.
Otherwise, we are packed and ready to go. I plan to get a few pictures of the fitting, and maybe I'll have luck getting someone to snap a few shots while we're testing out our new saddle.
