At the 2007 American College of Veterinary Medical Forum in Seattle, Dr. Anthony S. Moore gave a lecture on dogs with mammary tumors. He stated that mammary tumors are the most common type of tumors found in unspayed female dogs. He also mentioned a study that linked making healthy dog food choices for your dog reduces dog health care issues, such as the risk of mammary tumors.
Mammary tumors account for nearly half of all of the tumors found in female dogs. Mammary tumors occur three times more often in dogs than humans. Dogs also have the highest occurrence of mammary tumors than any other domesticated animal.
These mammary tumors can be a dog health care issue when they are found to be cancerous– which occurs about half of the time. By the time that the tumors have been diagnosed, the cancer has spread to other parts of the body. Females that are not spayed are 7 times more likely to develop breast cancer compared to spayed females. Research has proven the earlier you spay your dog the less chance they have for developing mammary cancer.
Another study has shown a significant reduction of the risk of developing mammary cancer in dogs that were thin at 9 to 12 months of age. Feeding your pet red meat may also increase the risk of a dog developing mammary cancer.
To lessen your dog’s chance of getting mammary cancer, have her spayed. Spaying before the first heat cycle is preferred. Ensure proper dog health care by feeding your dog a healthy diet and keeping her at a healthy weight.
