Thank you for submitting your question regarding Bruno. I recommend that he sees his veterinarian. He may need a procedure known as a fine needle aspirate to diagnose the mass. The veterinarian will use a small needle to collect a sample of cells to evaluate under the microscope. This will help to determine the type of mass and guide treatment. A histiocytoma is a common mass on the limb of a young dog. This is a benign growth. However, the outward appearance is the same as a cancerous growth known as a mast cell tumor. In the meantime, place an E-collar on him so that he does not cause any self-trauma. I hope this information helps!

    Thank you for submitting your question regarding Chevy. I recommend that he sees his veterinarian. He appears to have a mass on his paw. The veterinarian will likely use a small needle to collect a sample of cells to evaluate under the microscope. This will help to diagnose the mass as cancerous or benign. Surgery may be needed. In the meantime, place an E-collar on him to prevent him from licking the paw. I hope this information helps!
