This looks like a typica skin wart/skin tumor or cyst. Since it has been present for so long and has not grown at all, it is probably benign (non cancerous). It looks as if the area has been irritated somehow, probably by your dog scratching at it, and is now bleeding and may be infected. Or, if it is a cyst, the white material may just be cystic exudate. I would recommend cleaning the area with some dilute hydrogen peroxide then applying some antibiotic ointment to help prevent infection and to help it heal more quickly. Occasionally these need to be removed but only if they are a constant source of irritation or infection for the dog. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck!
