Yes, please do not blame yourself. Things sometimes happen, our dogs sometimes get sores. You are taking wonderful care of Annebelle. I know she felt very spiffy in her new haircut and Christmas scarf, none of that is to blame. It is just a boo-boo. I am glad to hear that you are able to get her in to get some medicine to fix everything up quickly. I am also excited to hear that Annebelle's cart will be arriving a few weeks before Christmas. It will take a little getting used to, so don't get discouraged. By Christmas she should be zip around with the rest of the pups. What a very exciting time this is for all of you.
