I called K on my cellphone and he came to pick us up. We took Bandit home and checked him out really good. Fortunately, he didn't break or sprain anything, and while I was on the phone with the vet's office he started tearing through the house like he usually does when he comes home from a walk - a very good sign! The vet said I should try to clean it a bit but that it didn't sound like anything that necessitated a visit. We got out the first aid kit, cleaned the wound with some antiseptic, and then wrapped it with gauze and tape.
The little patient is doing just fine!
