As I suspected, Jack definitely has demodex. The scraping on Friday was positive this time.
We're taking a wait and see approach, which is fine with me, since I'm trying to treat it naturally anyway. The vet said the only treatment they see any results with is ivermectin, and with the possibility of Jack being a BC mix, he will not take a chance with it (again, fine by me, I wouldn't either). So, since it's not bothering him (not itchy at all), we're going to watch it and see.
Callie emailed me her treatment, and I'm going to give that a try. For those who don't know, her recommendation is lots of vitamins and supplements, and dipping with tea tree oil. I've been loading him up with the vitamins already (thanks to Lilian's suggestion), and I gave him the first tea tree oil rinse on Thursday.
So any good thoughts you can spare him will be appreciated. I know it's a long road ahead, but I figured it couldn't hurt! Any suggestions are appreciated, too.
Lilly, Jack, Alex and Will
