I called the owner to see if she had any topical ointment or an e-collar. She did not, so I ran her over to the vet (1 block away) to get an e-collar and attempt to get some ointment. If she chewed on herself for the rest of the night, she would probably end up needing oral antibiotics. Even though I was the annoying client that I always complained about just walking in and asking for meds, she got what she needed and will hopefully have a more comfortable evening. Much thanks to QVAH for helping me out yet again!
