Hello, I am Dr. Peter a licensed Veterinarian. I would like to help. I need to ask you a few questions to be well informed and give you the best advise. There is no additional charge for information request.


1- Is she spayed?

2- Is the swelling limited to the nipple or is the gland (below the nipple) swollen as well?

Customer: replied 5 years ago.

no she is not spayed


yes the gland is swollen

Expert:  Dr. Peter replied 5 years ago.

In response to your question, this type of swelling of the mammary glands in dogs is a concern because it could be a tumor; 50% of mammary gland tumors in dogs are malignant. Your dog needs to have either a biopsy or fine needle aspirate to evaluate and determine if it is a tumor and if so, what type. Surgical removal, +/- chemotherapy is the recommendation if it is malignant; consider having this checked as soon as you can; the sooner we have a diagnosis the better the prognosis.


If you have additional questions I will be glad to answer them.
