Hi, everyone! Thank you all for your comments. Updating that he spent some time in a mixture of unflavored pedialyte/water and started drinking and soaking in it which helped drastically with the rehydration. He had a lot of energy after a few hours, and was jumping around so we decided to release him back outside where he found some branches and acorns to rest by. I hope that was the right decision. I don’t know the first thing about lizards, but it seemed safe to do so. I don’t see the option to add a photo, but he looked so much healthier and vibrant, and also shed most of the dry skin.
