Thanks to you all! Charlie Paper's doing well, his ear scabbed up nicely & we got him on anitboitics to prevent possible infection. He's not really affected by the incident, I took him back to my bf's house (while the other dog wasn't there) so he'd know its not a "house of pain". He doesn't seem to be tramatized, which is VERY good.
No clue what caused it. The 2 dog have had a disagreement before over a toy, but if I'd ever thought Charlie Paper was in danger, I wouldn't have put him in that situation. In fact, I've doggy-sat this particular dog before on 2 or 3 occassions & they both slept comfortably on my bed with me, one resting his head on the other's back. I guess something just didn't click on Friday. Oh well. The two of them will just remain separated. The dog's owner (who, like I said, is a friend of mine) is getting ready to go to grad school in Oregon, so it won't be an issue for much longer.
I will pass on everyone's love to my wiggley butt!!!
