Pet's info: Dog | Pit Bull Terrier | Male | unneutered | 50 lbs
Hello. My pitbull has formed this red lump on his chest. It is red, hairy, and as hard as a rock. I was reading online that a benine tumor would be able to move under the skin on which this does not. Anyone have any opinions please help!

Thanks for using Petco Pet Education Center, formerly Petcoach! Being benign vs. malignant is more based on how it looks under the microscope. It can still be benign even if it is not very movable. This could be a benign or malignant growth. 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!
