Anytime a new mass is noticed, I always recommend having it evaluated to see what it is and if anything needs to be done about it. Unfortunately, we can't tell anything about a mass by just looking at it or feeling it. Your vet can perform a simple test called a fine needle aspirate where they use a small needle to collect some cells from the mass, then look at them under the microscope. They may even need to send the cells to the lab for a pathologist to examine them, so we know what the mass is. If it is benign, you might not need to do anything about the mass at all, but if they see cells that worry them, they might recommend removing the mass. I am attaching a handout with more information about mammary tumors below in case the lumps are actually in the mammary gland. http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=1350 Good luck! I hope that was helpful. Thanks for using PetCoach.

A firm mass near or on the mammary gland of an intact, older female dog may be a mammary gland tumor (breast cancer). Tuppence should be examined by your veterinarian. A simple fine needle aspirate can be done in the clinic to collect samples for pathology. This may be able to diagnose the nature of the mass. It can be done in one visit. If the tumor is malignant, your veterinarian may recommend chest x-rays and surgery to resect the mammary gland or chain of glands on the affected side. Discuss payment plans or alternative financing such as CareCredit (www.carecredit.com) with your veterinarian. Consider asking family members or friends to help defray costs. You may also be able to secure financial assistance through local charities and Red Rover (www.redrover.org).

Being an intact, older female increases the risk for Duchess to develop mammary gland tumors. Have her examined by your veterinarian. A fine needle aspirate can be done on the suspect masses to collect samples for pathology. If a malignant mammary gland tumor is diagnosed, discuss treatment options with your veterinarian or veterinary oncologist. You can also simply monitor the masses for rapid change or growth. See your vet if they cause discomfort or impede movement.

Unfortunately a second opinion might be warranted, unless the vet did a needle aspirate of the mass and determined it is a benign type of tumor (there are different tumor types in the mammary glands of dogs, some are benign and don't spread while others are more aggressive and can spread). If your vet did an aspirate and determined the tumors are benign, then I would follow his recommendations. If your vet did no testing,however, I would request a needle aspirate and depending on the results x-rays of the chest. If your vet isn't interested, consider a second opinion. Here is an article with a little more info on this disease in dogs FYI: http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=1350
