Why are my dog's mammary glands swollen? - briefly
Swelling of a dog's mammary glands can occur due to several reasons, including infection or benign cyst formation. However, it is also important to note that swollen mammary glands can be an indication of malignant tumors in female dogs, especially if the swelling persists or increases in size. It is crucial to consult a veterinarian promptly for a proper diagnosis and appropriate treatment plan.
Why are my dog's mammary glands swollen? - in detail
Swollen mammary glands in dogs can be a cause for concern and typically indicate a hormonal imbalance or an underlying health issue. The most common reasons for this condition include pseudopregnancy, true pregnancy, and tumors.
Pseudopregnancy, also known as false pregnancy, is a common condition in female dogs that have not been spayed. It occurs when the dog's body goes through the hormonal changes of pregnancy without actually being pregnant. The mammary glands may swell and produce milk as a result of these hormonal fluctuations. This condition usually resolves on its own within a few weeks, but if it persists or becomes bothersome, veterinary intervention might be necessary.
True pregnancy is another possible cause of swollen mammary glands in dogs. If your dog has recently mated or you suspect she may be pregnant, the swelling could indicate the onset of lactation in preparation for nursing puppies. A veterinarian can confirm a pregnancy through various methods such as ultrasound or blood tests.
Tumors, both benign and malignant, are also a significant cause of concern when it comes to swollen mammary glands in dogs. Mammary tumors are common in older female dogs, with about 50% being malignant. Early detection is crucial as treatment options and prognosis vary depending on the type and stage of the tumor. Regular veterinary check-ups and monitoring for any changes in the mammary glands can help in early diagnosis and intervention.
In addition to these primary causes, other factors such as infections or inflammation in the mammary glands may also lead to swelling. Any unusual swelling of the mammary glands should be promptly evaluated by a veterinarian who can perform a thorough examination and necessary diagnostic tests to determine the underlying cause and appropriate course of treatment.
