Swollen, painful, and reddened mammary glands in dogs indicate an inflammatory response that can be triggered by various causes, including infections, hormonal changes, or trauma.

Can Occur with the Following Diseases:

Basics and possible causes

The mammary glands of female dogs are exposed to hormonal fluctuations during their life cycle, especially during estrus, pregnancy, and lactation. These hormonal changes can make the mammary gland tissue more susceptible to inflammatory conditions.

Mastitis is one of the most common causes of swollen and painful mammary glands in lactating female dogs. This bacterial infection occurs when bacteria enter the mammary gland through the teat and cause inflammation.

Another common reason for swollen mammary glands is a false pregnancy, in which hormonal changes occur without an actual pregnancy. This can lead to temporary swelling and pain in the mammary glands.

In rare cases, Tumors in the mammary glands can also cause swelling and pain. These can be benign or malignant and are more common in older, non-spayed female dogs.

Traumatic injuries to the mammary gland region, such as bites or blows, can also lead to swelling, redness, and pain, as the tissue reacts with inflammatory conditions.

Typical accompanying symptoms

  • Loss of appetite: Many dogs with painful mammary glands show a reduced food intake, as the pain affects their general health.
  • Lethargy: A general feeling of discomfort and weakness can occur, causing the dog to be less active than usual.
  • Fever: An elevated body temperature may indicate a systemic infection associated with inflammation of the mammary glands.
  • Behavioral changes: The dog may become irritable or aggressive when the mammary glands are touched, or it may pay excessive attention to the affected area by Licking or biting it.
  • Discharge: Sometimes a purulent or bloody discharge can be observed from the teats, especially in the case of a bacterial infection.
  • Skin changes: The skin over the affected mammary glands may be taut, shiny, or even ulcerated if the inflammatory conditions is severe.

When to visit the vet?

A visit to the veterinarian is essential if the swelling of the mammary glands is accompanied by Fever, severe Pain, or a purulent discharge. These symptoms indicate a serious infection that requires medical treatment.

If the swelling does not subside within a few days or worsens, a veterinarian should also be consulted to clarify the cause and initiate appropriate therapy.

In older female dogs that have not been spayed and show persistent swelling of the mammary glands, it is important to see a veterinarian to rule out the possibility of Tumors.

If there are signs of severe discomfort or Behavioral changes, a veterinary examination should also be carried out to maintain the animal’s quality of life.

Symptom recognition for animal owners and veterinary diagnostic procedures

It is important for the pet owner to regularly monitor the health and behavior of their dog. Pay attention to signs of Swelling, redness, or discomfort in the area of the mammary glands.

The veterinarian will perform a thorough clinical examination to assess the Swelling and identify other symptoms. This may include palpation of the mammary glands and a check of body temperature.

For further diagnosis, the veterinarian can take blood tests to detect signs of infection or inflammatory conditions in the body. A bacteriological smear or a sample of the discharge can help to identify the pathogen.

Imaging techniques such as ultrasound or X-rays can be used to assess the internal structures of the mammary glands and rule out Tumors or cysts.

In some cases, a biopsy may be necessary to take tissue samples and examine them for malignant changes.

What can pet owners do and professional therapy options

As a first measure, the pet owner can gently clean and cool the affected area with lukewarm water to reduce inflammatory conditions and relieve the Pain. Avoid massaging or pressing the area too much, as this could increase the Pain.

Make sure your dog has access to plenty of water and try to provide him with a calm and stress-free environment to support his recovery.

It is important to follow the veterinarian’s instructions regarding medication and care exactly. Do not give your dog any medication without veterinary advice, as some human pain relievers can be harmful to dogs.

Observe your dog’s condition closely and note any changes or deteriorations to share this information with your veterinarian. This can help to adjust the treatment and promote healing.

Outlook on current research

Swelling, pain, and redness of the mammary glands in dogs, also known as mastitis or inflammation of the mammary gland, is a common symptom that can indicate various underlying causes. A dog’s mammary glands can swell for various reasons, including bacterial infections, hormonal changes, or even Tumors. Current research focuses on developing better diagnostic methods to identify the exact cause of the symptoms early and treat them accordingly.

A significant area of research is the development of new imaging techniques that allow veterinarians to examine the internal structures of the mammary glands in detail without having to perform invasive procedures. Ultrasound and magnetic resonance imaging (MRI) are technologies that are used in some studies to analyze the structural changes in the mammary glands and to distinguish between inflammatory and non-inflammatory causes.

Another important area of research is the study of the microbial flora of the mammary glands. Through DNA sequencing and microbial cultures, scientists are trying to identify the most common bacteria involved in infections in the mammary glands. This information could lead to the development of targeted antibiotic treatments that shorten recovery time and reduce the risk of antibiotic resistance.

In addition, the role of the immune system in the development of mastitis is being further explored. Researchers are investigating how the dog’s immune system responds to inflammatory stimuli in the mammary glands and which immunological markers could serve as early warning signs of an infection. These markers could be used in the future as diagnostic tools to detect and treat mastitis early.

Finally, there are also research approaches that deal with the prevention of mastitis. Nutritional studies are investigating how certain nutrients and dietary supplements can strengthen the immune system and promote the health of the mammary glands. The hope is that by improving the general health of the dog, the risk of mastitis and other inflammatory conditions can be reduced.

Frequently asked questions

  1. What are the most common causes of swollen mammary glands in dogs? Swollen mammary glands in dogs can be caused by several factors, including bacterial infections, hormonal changes during the cycle or pregnancy, and in some cases Tumors. An accurate diagnosis by a veterinarian is crucial to determine the cause and initiate appropriate treatment.

  2. How can I tell if the swelling of the mammary glands is painful for my dog? Dogs often show Pain through Behavioral changes. If a dog is in Pain, it may yelp, growl, or be reluctant to be moved when the affected area is touched. Loss of appetite, lethargy, and increased Licking or biting of the affected area can also be signs of Pain.

  3. What tests can be performed to diagnose the cause of swollen mammary glands? A veterinarian can perform several tests to determine the cause of the Swelling. These include blood tests to detect inflammatory markers, as well as imaging techniques such as ultrasound or X-rays to assess the structure of the mammary glands. In some cases, a biopsy of the mammary gland may be necessary to make a definitive diagnosis.

  4. Can an infection of the mammary glands heal on its own? While mild infections may improve on their own in some cases, it is important that a veterinarian assesses the situation. Untreated infections can worsen and lead to more serious health problems. Antibiotics are usually required to treat the infection effectively.

  5. Are all dog breeds equally susceptible to swollen mammary glands? All dog breeds can be affected by swollen mammary glands, but female dogs that have not been spayed or have recently had puppies are at higher risk. Certain breeds may also be more susceptible due to genetic predispositions, but this varies greatly.

  6. What treatment options are available for swollen mammary glands? Treatment depends on the cause. Bacterial infections are usually treated with antibiotics. For hormonal causes, hormone therapy or spaying may be considered. Surgery may be necessary for Tumors. Pain relievers and anti-inflammatory drugs can also be used to relieve symptoms.
