My dog has a lump on her leg. What is it and can I treat it at home?

I just noticed this on my dogs ankle when she was licking herself. I'm not sure how long she has had it, & there are no symptoms showing of illness. I thought she was bleeding but she's not. I cleaned the surface & she showed no sign of pain. What is this? Can I treat it at home?

Thank you for submitting your question regarding Diamond. She appears to have a mass that has grown on her leg. I recommend that she sees her veterinarian to have it evaluated. She will need a procedure known as a fine needle aspirate to determine if the mass is cancerous or not. The veterinarian will use a small needle to collect a sample of cells to evaluate under the microscope. There is a benign growth known as a histiocytoma that is more common in young dogs. There is also an aggressive cancerous mass known as a mast cell tumor that can have the same outward appearance. If it is cancerous, the mass will be difficult to remove given its location. In the meantime, do not allow her to lick the mass. I hope this information helps!
