Fleas are the most common cause of developing sores by the tail base. Some dogs are allergic to fleas where just a bite or two may cause them to itch excessively. This itching can damage the skin, resulting in a skin infection. Other environmental allergies, food allergies or mange may cause similar signs. At this point, I recommend taking Freya to her vet for further evaluation and treatment. Her vet can discuss options for high quality flea prevention (e.g. Nexgard, Comfortis or K9 Advantix II) and may need to prescribe a course of antibiotics if a bacterial skin infection is present. Until you get to the vet, try putting an e-collar (cone) on Freya to prevent her from causing further damage to her skin. I hope she feels better soon!
