My roommate and I have a year and a half old blue nose pit-bull that has a big mass on his stomach. The mass just started leaking out blood today, and we are not sure what it could be or how do we stop the bleeding. The mass appeared after taking a walk at the park around the corner from our house. What do you think might have caused this? What can we do to help stop the bleeding?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good night!
