Hi, I have noticed a small lump on the testicle of my 17 month old Cane Corso, and was wondering if you had an idea of what it could potentially be, I have him booked in with my local vet on Tuesday to check this, but am hoping for some peace of mind

Hi there. I am glad to hear you already have an appointment scheduled. Possible causes would be a pustule from a skin infection, an ingrown hair, a histiocytoma which is a benign growth of young dogs that typically resolves on its own, or of course something more concerning such as cancer. However, at his young age cancer is highly unlikely. They may recommend a needle aspirate to help determine the cause. Best of luck and I hope he improves soon. Thank you for using Pet Coach.
