Hi, tonight we noticed a lump on my dogs back. It is quite big, and it is bleeding and smells bad as if infected. Can you offer any advice on what it may be? Thank you

If you are noticing an odor, it's might be infected. This bump could be an infected cyst, a foreign body trapped under the skin or a ruptured tumor. I recommend to protect the area from any licking (Nala may need to wear an elizabethan collar at all times) and have her examined by the veterinarian within the next 24 hours. I hope this helps.
