My female dog.... 1st it was one nipple, now two. Nipple has formed a bulged out bump that bleeds, and the other is bleeding with no bump. Taking to vet, but wanted to be a bit knowledgeable on what it might be. Thank you very much for any advise!

This kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration). Differentials include skin cysts, infections, benign or more sinister type of tumors.
