My dog keeps biting her leg until it bleeds. Why and what to do?

Question

My dog is biting her back leg and making it bleed what is the cause and treatment for this. Pet's info: Dog | Mixed Breed | Female | spayed

Jennifer Summerfield, DVM CPDT-KA · Accepted Answer

The most likely cause would be a skin condition of some kind, causing her to be itchy - some common possibilities would include allergies, fleas, a bacterial or fungal skin infection, or skin mites (mange). Treatment will depend on what the cause is, so I would recommend having her examined by a vet - he/she can do a simple test called a skin scrape if needed to help diagnose the problem. In the meantime, I would suggest getting her an e-collar (plastic cone) to keep her from continuing to chew at her leg and make things worse until you can get her in to see a vet.
