Hello. At this age I would be concerned about cancer, but it may also be an infection in one of her anal glands, a parasitic infection, or colitis. It is best to see your vet about this as soon as possible so that little Perla does not have more problems. thanks for using Petco Pet Education Center, formerly Petcoach.
