My dog has pink lumps on her body. Why are some turning black?

Updated On September 23rd, 2025

Pet's info: Dog | Jack Russell Terrier | Female

Around 5 - 10 wrinkly pink lumps all over dogs body. Some are turning black. Might be reading into it too much but might be loosing a bit of weight. Lost appetite for 2 days a few weeks ago. Not a lot of energy but she was rescued from a pound after being used for breeding. Just concerned about them turning black? Thanks.

Based on your picture these look like adenomas which are a benign type of skin mass. They can secrete material that is dark, but they can also occasionally become infected. Since Evie has had some behavior changes as well it would be a good idea to have your veterinarian examine the masses and confirm the diagnosis. Adenomas are benign and generally don't need to be removed unless they are infected or bothering the dog.
