Does the saying "Don't quit your day job" mean anything to you? LOL

Don't be so hard on yourself, grooming a dog is HARD work (there is a real reason why it costs so much), but not to worry......it is only hair, it will grow back. Just be glad you did not cut the skin (something I have seen all too often when owners get adventurous)

But I really think as part of your penance you need to post pictures.
