Pet's info: Dog | Boxer | Male | neutered | 10 years and 7 months old | 110 lbs

my 10 year old boxer has a large red lump on the top of his right back paw. It is between the toes back away from his nails. You can touch it and he does not show signs of pain but it looks like it would hurt. What could it be?

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. Common tumors in this region include melanomas, squamous cell carcinomas, mast cell tumors and soft tissue sarcomas, among others. 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!
