The crazy thing is, it's not his stitches he's obsessed with. Instead, he's taken to licking the spot on his arm (foreleg? whatever) where he was shaved for the IV insertion. So I've had to wrap it with a pad and some gauze in order to prevent him from making it any worse.
So he started licking the bandage, which moves it out of place (and makes the bandage all wet). So I sprayed it with bitter apple. Which apparently just makes the bandage zesty and delicious.
"Just correct him when he does it," you say? I did that for a while, and it seemed to be very effective...he's fine when I'm watching him like a hawk. But the sneaky little bugger will be clever about it just to spite me. "OH, look at this wonderful toy I'm playing with here on the floor. I think I'll just position it right next to...my arm while I...nonchalantly...sneakinareallyquickSLURRRRP!"
"Fine," I say. "I'm getting The Cone."
