Hello. I am so sorry for your worries with Chloe. If this scab has been there for a while, I would definitely have your veterinarian check this out. It could be an infection, abscess, a burn, dermatitis, or even possibly skin cancer. In an older dog like Chloe, unless there was a recent trauma that might explain this, I would highly recommend having your veterinarian check this out soon. I hope it is nothing serious, but better safe than sorry. Thanks for contacting Petco Pet Education Center, formerly Petcoach.
