Thank you for documenting Sebastian's IVDD. It'll help us all. Yes, and excellent advice about finding a veterinary practice (in advance) whom knows about IVDD, because ours first vet certainly didn't know. Btw, Dodgerslist.com had a list of them.
Sebastian's stitches look nice. Good that he can already do stuff, like potty, on his own. Wagging his tail will come back later, you'll see. We had to express Buddy's bladder for a while after his surgery, so you're already ahead of his schedule. Yay!
