What's this black spot on my senior dog's nipple? Is it cancer?

Hi, I have miniature poodle 11 years old. I noticed yesterday a black spot right on top of her nipple. I just want to know if it’s a possibility that it is breast cancer. And if it is is better to put her down? And do they get worst through time ? I have never seen this on her skin and I was reading online and it was saying that it is breast cancer. And she has never had puppies.

Since she is not spayed and has gone through heat cycles, she is at a higher risk of mammary cancer. These usually are nodules you can feel along the mammary chain. I would have your vet take a look at the black spot on her nipple. You can always upload up to 3 pictures when submitting a question also. Just from finding a black spot on her nipple or even if you feel a nodule or two along her mammary chain at this point if she is doing well I would not recommend putting her down.
