Without seeing it in person, I can't say what it is for certain. I can say that nipples are not usually right next to each other. It could be possible he has an extra nipple, but I would be more likely to think it's a lump of some sort. It could be a benign tumor, a wart, or a malignant tumor, among other skin lumps. I would recommend taking Apachie into your vet to have them check out the lump. Any suspicious lumps should be investigated by your vet. Your vet can perform a simple test on it called a fine needle aspirate to help identify it. To do this, your vet will stick a small needle into the lump to get a sample of its cells, and examine the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform.
