Just home, Nico was a model patient. The vets said that plan a is we treat it as a sting. He's had a steroid injection and antirobe antibiotics. He's temp was high at over 104, but he's not showing any signs of pain from the swelling, (which obviously we had noticed) so she thinks it highly unlikely to be an abscess. She can't rule out a foreign body and we have to see how he responds to the treatment before we decide if we need a plan b. Whatever happens, it's back to the vets Saturday morning.
This photo shows some of the swelling on his neck and under his chin, but really doesn't show the true extent of the amount of swelling that's under that rough.
