How To Find Dog Lymph Nodes [Complete Guide]

In this post, we will discuss the anatomy of a dog’s body and provide step-by-step instructions on finding and identifying canine lymph nodes.

We will also cover some tips for easy identification and examine the possible consequences of inflammation in these glands.

Key Takeaway

• Dog lymph nodes are small, bean-shaped glands that produce cells designed to fight infection and disease as part of the dog’s immune system.
• Dog lymph nodes can be located by gently feeling under the jaw, in front of the shoulder blades, in the armpit area, in the groin area, and behind the knees, as these are the most prominent lymph node locations in a dog’s body.
• Dogs typically have between 400 to 450 lymph nodes, which are crucial components of their immune system responsible for producing cells that fight infection and disease.

What Are Dog Lymph Nodes?

Dog lymph nodes are an integral part of the canine immune system. They are small glands located strategically along the lymph circulatory system and house many lymphocytes, which process antigens for antibody production.

These nodes help regulate a dog’s immune functions, transporting infection-fighting cells throughout the body.

Lymph nodes can be found in many different places in a dog’s body, both internally and externally.

Enlargement of these nodes, known as lymphadenopathy, can be due to various causes, including bacterial, viral, or fungal infections, allergies, inflammation, or cancer.

How To Find Dog Lymph Nodes

Here is a complete guide on how to find the lymph nodes in dogs:

How To Find The Submandibular Lymph Nodes In Dogs

These lymph nodes are situated under your dog’s jaw. To locate them, gently place your fingers underneath your dog’s jaw and feel for small, firm structures. Be cautious not to confuse them with the larger salivary glands that manufacture saliva.

How To Find The Prescapular Lymph Nodes In Dogs

The prescapular lymph nodes can be identified in front of the shoulder blades of your dog. To find these, position your hand on your dog’s shoulder and move your fingers towards the neck. If they’re swollen, you should be able to sense these nodes.

How To Find The Axillary Lymph Nodes In Dogs

The axillary lymph nodes dwell in your dog’s armpits. To check these, lift your dog’s front leg and softly feel the area where the leg links with the body.

How To Find The Inguinal Lymph Nodes In Dogs

These nodes can be found in the groin region of your dog. To find them, raise your dog’s hind leg and touch the area where the leg connects to the body.

How To Find The Popliteal Lymph Nodes In Dogs

The popliteal lymph nodes are located at the back of your dog’s knees. To find these, bend your dog’s hind leg and feel the area behind the knee.

How Many Lymph Nodes Do Dogs Have?

Dogs have numerous lymph nodes located throughout their bodies. While the exact number can vary, dogs typically have between 400 to 450 lymph nodes.

Each set of lymph nodes has a specific role in helping your dog’s immune system function properly.

Submandibular Lymph Nodes

The submandibular lymph nodes are located under your dog’s jaw. They play an important role in filtering lymph fluid from the head, neck, and parts of the respiratory tract. If these lymph nodes become enlarged, it can be due to an infection or inflammation in these areas.

Prescapular Lymph Nodes

The prescapular lymph nodes are located near the shoulders, just in front of the shoulder blades. They filter lymph fluid from the upper limbs, chest, and upper wall of the abdomen. Swelling in these lymph nodes could indicate an issue with these areas.

Axillary Lymph Nodes

The axillary lymph nodes are situated in the armpit area. They also play a role in draining lymph fluid from the upper limbs, chest, and upper wall of the abdomen. Enlargement of these lymph nodes may suggest an infection or inflammation in these areas.

Inguinal Lymph Nodes

The inguinal lymph nodes are found in the groin area. They are responsible for filtering lymph fluid from the lower limbs, the lower wall of the abdomen, and the lower back. Swelling in these lymph nodes might indicate an infection or inflammation in these regions.

Popliteal Lymph Nodes

The popliteal lymph nodes are located behind the knees. These nodes drain lymph fluid from the lower limbs and can become swollen due to an infection or inflammation in these areas.

FAQs

Q: What are the Symptoms of Swollen Lymph Nodes in Dogs?

A: The symptoms of swollen lymph nodes in dogs may include lumps or swellings in the affected areas, fever, loss of appetite, weight loss, fatigue, and changes in behavior. It is important to note that swollen lymph nodes can be a symptom of various underlying conditions, including infections, inflammation, and cancer.

Q: What are the Causes of Swollen Lymph Nodes in Dogs?

A: Swollen lymph nodes in dogs can be caused by a variety of factors, such as infections (bacterial, viral, or fungal), inflammation, cancer (lymphoma), immune system disorders, and even certain medications. It is best to consult with a veterinarian to determine the underlying cause.

Q: How are Swollen Lymph Nodes in Dogs Diagnosed?

A: To diagnose swollen lymph nodes in dogs, a veterinarian will conduct a thorough physical examination, including feeling for enlarged lymph nodes. Additional diagnostic tests may include blood tests, fine needle aspirate (using a needle to obtain a sample of the lymph node cells), biopsy (removing a small piece of the lymph node for further analysis), imaging tests, and other laboratory tests.

Q: What are the Treatment Options for Swollen Lymph Nodes in Dogs?

A: The treatment options for swollen lymph nodes in dogs depend on the underlying cause. If the swelling is due to an infection, appropriate antibiotics or antifungal medications may be prescribed. In cases of lymphoma or other cancers, treatment options may include chemotherapy, radiation therapy, or surgery. It is important to follow the veterinarian’s recommendations for the best course of action for your dog.

Q: What is the Prognosis for Dogs with Swollen Lymph Nodes?

A: The prognosis for dogs with swollen lymph nodes depends on the underlying cause. In cases where the swelling is due to a treatable infection or inflammation, the prognosis is generally good. However, if the cause is cancer, such as lymphoma, the prognosis can vary depending on the stage of the disease and the overall health of the dog. It is important to discuss the prognosis with your veterinarian.

Q: What is Lymphoma in Dogs?

A: Lymphoma in dogs is a type of cancer that affects the lymphatic system, which is part of the immune system. It is characterized by the uncontrolled growth of lymphocytes, a type of white blood cell, causing the lymph nodes and other lymphoid tissues to enlarge. Lymphoma can affect various parts of the body and may require a combination of treatments.

Q: When Should I Consult a Veterinarian for Swollen Lymph Nodes in My Dog?

A: It is recommended to consult a veterinarian if you notice any swelling or enlargement of your dog’s lymph nodes that lasts for more than a week, is associated with other symptoms such as fever or weight loss, or if you have any concerns about your dog’s health. A veterinarian will be able to properly evaluate your dog and provide appropriate diagnosis and treatment options.

Q: Can Swollen Lymph Nodes in Dogs Be Treated with Antibiotics?

A: Swollen lymph nodes in dogs caused by infections may be treated with appropriate antibiotics or antifungal medications. However, it is important to note that not all cases of swollen lymph nodes are due to infections, and the underlying cause should be determined by a veterinarian before initiating any treatment.

Q: Can Swollen Lymph Nodes in Dogs Go Away on Their Own?

A: Swollen lymph nodes in dogs may go away on their own if they are caused by temporary infections or inflammation. However, it is important to monitor the swelling and consult with a veterinarian for a proper diagnosis and treatment plan, as persistent or worsening swelling may indicate a more serious underlying condition.
