My unspayed dog has nipple lumps. Could it be breast cancer?

Updated On September 23rd, 2025

Pet's info: Dog | Maltipoo | Female | unspayed | 10 years and 2 months old | 10 lbs

I noticed today my dog has multiple tiny lumps right around one of her nipples. She’s always had spots that have a bit more fat to them (im not really sure what it’s called) but never hard tiny lumps. I’m worried because she’s not spayed and I know breast cancer is a risk. I’m still young and can’t afford taking her to the vet myself, and my parents tell me no most of the time unless it’s visibly very serious. Idk what to do or think

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.
