OMG! That's all I could think after reading this. I'm so sorry. You have just been through a nightmarish experience. It sounds like Wosie is recovering nicely and I sure hope there won't be any need for surgery. I hope you are recovering as well. An injured puppy will certainly bite. I hope your poor finger will be OK, too. I know it had to really hurt. Let us know what the vet says this evening. Talk about a freak accident. She certainly had one.
