How should I care for this pre-loved Curly Teddy?

My first thrift store find! The tag reads 2011 Curly Teddy 013439. No smells, still very soft, and the tag is attached. Perfect condition really.

I want to keep the tags on!

Would it be okay to just soak, wash, and dry? Better to unstuff? (And why can't I find the seam? Lol.) I don't want to tumble dry so I'll probably just airdry... I see some other recommendations to freeze as well. Just wanted to consult the experts before I do anything I regret! Thanks in advance!

ETA: Is it okay to use Dawn soap? Or is regular laundry detergent better? I won't be using fabric softeners or anything else like that.
