My boy Frank has a red, bulbous protrusion poking out of his anus. While he's been eating and pooping normally, it's an ugly sight and he constantly drips bloody puss. I took him to a vet a month ago, but they were of no use. He has an appointment with another vet in 2 weeks. In the meantime I've tried hemorrhoid cream but to no avail. He has an appointment with another vet in a couple of weeks. Does anyone know what this is and how I might treat it?
