Friday night I got off work at midnight. I was looking forward to getting a shower and relaxing a little bit before getting to bed. I get home and get inside and realize the dog is still outside, my wife fell asleep before she let the dog in. Cassie, my mix German shepherd, is an inside dog but we chain link fenced an acre of the property in that encompasses the deck off the back of the house. I find Cassie, the dog, by the door, tail wagging to beat hell happy to see me. I let her in and I thought she had one of her toy stuffed animals in her mouth, but I noticed her "toy" had a long flat tail. I told her drop it, so she drops the critter and looks up at me, that's when I notice the huge gash in her face. The muskrat must have bitten her in the side of the face tearing a v shape in her cheek. I must have said "shit" loud enough that it woke the wife up. When she saw Cassie she got a little frantic. I told her to hold a cold compress on Cassie face while I called the vet. The vet had us give her Bayer aspirin for the pain and keep the compress on till the bleeding stopped and we could get her in to the vet in the morning.
So, she got stitches, doubt she learned her lesson. The muskrat had no head though, so the bite must have really pissed her off.
Poor girl.
