This is likely her anal gland that is inflamed and infected and likely to rupture. There are anal glands found on every dog that are just inside the rectum roughly at the 4 and 10 o'clock position that should empty on their own when your pet poops. However, some pets have a hard time doing this, and these will fill up and become infected. You will need to take Copper to your vet soon to have these flushed out, lanced, and then he will need to be placed on antibiotics and anti-inflammatory medication. I hope that your pet Copper gets this resolved soon. Talk with your vet about getting his anal glands expressed regularly at the vet to hopefully prevent this from happening in the future. Best of luck to you both. Take care.
