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.

HI, thanks for using Petco Pet Education Center, formerly Petcoach! If the liquid coming from her nipple is brownish and there is a mass in the breast tissue it is likely a cystic mammary tumor. A lot of which are benign. Some breast masses in dogs are cancerous though. Usually it is recommend to spay them and remove the breast mass. Hormones play a role in the formation of the tumors. I'd get the mass checked out by your Vet and discuss removing it to biopsy. Good luck!

Breast cancer is definitely a concern. It could be either benign or malignant, so Miny really needs to see a vet. They can collect a sample with a needle for evaluation under the microscope to determine if it is a big scary thing or a smaller worrisome thing.

Is it just a deformed nipple? Or should we take her in to get it checked out? It's on her underside. She's a Labrador and bull dog mix if that's important.
