How To Check a Dog’s Lymph Nodes

This informative guide is designed with pet owners in mind, providing a step-by-step process to conduct a basic health examination at home.

Lymph nodes are crucial parts of the dog’s immune system, and changes in their size or texture can be an early indicator of health issues.

In this blog post, we will help you understand where these lymph nodes are located and how to gently check them, allowing you to monitor your furry friend’s health more effectively.

Key Takeaway

• To check a dog’s lymph nodes, you gently palpate or feel the areas where the nodes are located – under the jaw, at the front of the shoulders, on either side of the windpipe below the jawline, in the groin region, and at the back of the knees – for any swelling or abnormalities.
• Dog lymph nodes are small, bean-shaped glands that form an essential part of the immune system, helping to filter harmful substances and fight off infections.
• Dogs have numerous lymph nodes located throughout their body, with five sets of peripheral lymph nodes that are easily palpable: submandibular (beneath the jaw area), prescapular (lower neck, near the chest), axillary (armpit), inguinal/femoral (inner thigh), and popliteal (behind the knees).

What Are Dog Lymph Nodes?

Dog lymph nodes are an integral part of a dog’s immune system.

They are small glands located in various parts of the body, such as under the jaw, between the shoulder and the neck, under the front legs, and in the inguinal region of the back legs.

These nodes house lymphocytes that process antigens for antibody production and help fight against infections.

The lymph nodes can become swollen due to various reasons including bacterial, viral, fungal, or parasitic infections, inflammation, allergies, or even cancer-like lymphoma.

Swollen lymph nodes in dogs might appear as firm, rubbery lumps that move freely beneath the skin and are typically not painful.

How To Check a Dog’s Lymph Nodes

• Identify the location of the lymph nodes in your dog.
• Use a gentle touch to feel the area.
• Check for any swelling or lumps.
• Take note of any changes in size or consistency over time.
• Look for other signs of illness in your dog such as loss of appetite, lethargy, or changes in behavior.
• If you find any abnormalities or if your dog shows signs of illness, take them to a veterinarian for further examination.

Identify the Location of the Lymph Nodes in Your Dog

The first step is to know where to look. The most commonly checked lymph nodes in dogs are located under the jaw, in front of the shoulders, and behind the knees.

Use a Gentle Touch to Feel the Area

Once you’ve identified the location of the lymph nodes, gently feel them with your fingers. Remember, lymph nodes are usually round and move slightly when touched.

Check for Any Swelling or Lumps

Normal dog lymph nodes are small and may not be noticeable. If they’re swollen, they can be the size of a bean or larger. So, it’s important to check for any unusual swelling or lumps.

Take Note of Any Changes in Size or Consistency Over Time

Regular checks can help you notice any changes quickly. If you find that the lymph nodes have changed in size or consistency, it could indicate a health issue.

Look for Other Signs of Illness in Your Dog

In addition to checking the lymph nodes, observe your dog for other signs of illness such as loss of appetite, lethargy, or changes in behavior.

If You Find Any Abnormalities, Take Your Dog to a Veterinarian

If you discover any abnormalities during your check or if your dog is showing signs of illness, it’s crucial to take them to a veterinarian for further examination. This will ensure that any potential health issues are addressed promptly.

What Causes Swollen Lymph Nodes In Dogs?

1. Infections: One of the most common causes of swollen lymph nodes in dogs is due to an infection within the body. This could be bacterial, fungal, or parasitic infections. Infections may even be within the lymph node itself.
2. Diseases: Certain diseases such as demodectic mange, puppy “strangles” (i.e., juvenile cellulitis), and tick-borne diseases (e.g., Lyme disease) can also lead to swollen lymph nodes.
3. Lymphoma: Lymphoma, a type of cancer, is the most common reason for enlarged lymph nodes. There are over 30 types of lymphoma in dogs.
4. Local Respiratory Infections or Dental Disease: These can cause the submandibular lymph nodes to enlarge.
