Why is my dog's breast swollen? - in detail

Swelling in a dog's mammary glands, commonly referred to as "breasts," can indicate several underlying conditions, ranging from benign to malignant. It is crucial for pet owners to be aware of these possibilities and to seek veterinary care promptly if they notice any changes.

One of the most common causes of swollen mammary glands in dogs is mastitis, an infection that typically occurs during lactation or shortly after weaning. Mastitis can be caused by bacteria such as Staphylococcus and Streptococcus, which enter through the teat openings. Symptoms may include warmth, redness, pain, and discharge from the affected glands. If left untreated, mastitis can lead to systemic infection, requiring prompt veterinary intervention.

Another potential cause of swollen mammary glands is a mammary tumor. Dogs are particularly susceptible to these growths, with approximately 50% of female dogs developing a mammary tumor at some point in their lives. While not all mammary tumors are cancerous, it is essential to have any lump or swelling evaluated by a veterinarian. Early detection and treatment significantly improve the prognosis for canine mammary cancer.

Hormonal imbalances can also contribute to mammary gland enlargement in dogs. Elevated levels of estrogen and progesterone, often due to hormonal disorders such as false pregnancy or ovarian cysts, can stimulate the growth of mammary tissue. This condition is typically benign but may require veterinary management to address the underlying hormonal imbalance.

In some cases, swollen mammary glands in dogs can result from trauma or injury to the area. Blunt force trauma, bites, or other injuries can cause inflammation and fluid accumulation, leading to visible swelling. Prompt veterinary care is necessary to assess the extent of the damage and provide appropriate treatment.

Regularly examining your dog's mammary glands is an essential part of preventive healthcare. Early detection of any abnormalities allows for timely intervention and can significantly improve the outcome. If you notice swelling or any other changes in your dog's breasts, consult your veterinarian immediately for a thorough examination and appropriate diagnostic tests.
