Prescapular lymph nodes are found in the shoulder area of dogs and other animals. They help to filter out foreign bodies and bacteria, which can then be destroyed by a healthy immune system.
However, if these lymph nodes become enlarged or inflamed, it could indicate an underlying health issue.
In this blog post, we’ll discuss the causes, symptoms, and treatment of swollen prescapular lymph nodes in dogs.
We’ll also touch on best practices for keeping your pet healthy, so they are less likely to develop this condition.
- The purpose of prescapular lymph nodes in dogs is to filter harmful substances from the lymphatic fluid and play a crucial role in the dog’s immune response to fight off infections and diseases.
- Prescapular lymph nodes in dogs are located just in front of the dog’s scapula or shoulder blade.
- The enlargement of prescapular lymph nodes in dogs can be caused by various conditions such as infections, inflammation, immune diseases, or cancers like lymphoma.
Purpose of Prescapular Lymph Nodes In Dogs
Prescapular lymph nodes in dogs, also known as superficial cervical lymph nodes, are located where the neck and shoulder meet.
These nodes are an integral part of a dog’s immune system, working vigilantly to fight off any invaders such as viruses or bacteria.
When these nodes enlarge, a condition known as lymphadenopathy might be indicative of an infection within the body or a disease triggering an immune response.
Swelling in these nodes can sometimes go unnoticed unless the enlargement is significant.
Where Are Prescapular Lymph Nodes Located in Dogs
Prescapular lymph nodes, also known as superficial cervical lymph nodes, are located in dogs where the neck and shoulder meet.
They are situated cranial to the shoulder joint in the subcutaneous tissues, often adjacent to or under the skin.
These nodes are found in front of your dog’s scapula or shoulder blade. They are among the peripheral lymph nodes that are commonly located in dogs, along with the cervical nodes under the back of the jaw.
To palpate a dog’s prescapular lymph node, it is easiest when the dog is standing. One would gently palpate over the cranial shoulder joint, progressively deepening the palpation in this area.
Causes of Enlarged Prescapular Lymph Nodes In Dogs
- Bacterial or viral infections: These can cause swelling in the lymph nodes as the body fights off the infection.
- Autoimmune diseases: Conditions where the immune system mistakenly attacks the body’s own cells can lead to inflammation in the lymph nodes.
- Metabolic disorders: Certain metabolic disorders can cause lymph node enlargement.
- Parasitic infections: Parasites can trigger an immune response leading to swollen lymph nodes.
- Inflammatory conditions: Conditions like dermatitis can cause swollen prescapular lymph nodes.
- Cancer: Lymphoma or other types of cancer can cause enlargement of the lymph nodes.
- Fungal infections: Certain fungal infections can cause an immune response leading to swollen lymph nodes.
- Allergic reactions: Severe allergic reactions can cause inflammation in the lymph nodes.
- Trauma: Physical injury near the lymph node can cause it to swell as part of the healing process.
Symptoms of Enlarged Prescapular Lymph Nodes In Dogs
- Swelling of the lymph nodes, particularly in the neck and shoulder area
- Lethargy or decreased energy levels
- Loss of appetite or anorexia
- Weakness or difficulty moving
- Increased thirst and urination
- Noticeable weight loss
- Difficulty breathing or coughing (in severe cases)
- Changes in behavior or mood.
Diagnosis of Enlarged Prescapular Lymph Nodes In Dogs
Diagnosis of prescapular lymph nodes in dogs includes:
Step 1: Initial Consultation and Physical Examination
The first step in diagnosing issues with prescapular lymph nodes in dogs is a thorough consultation and physical examination by a veterinarian.
The vet will discuss any symptoms your dog has been experiencing and will physically examine your dog, paying close attention to the areas where lymph nodes are located. They will palpate (feel) these areas to check for any swelling or abnormalities.
Step 2: Fine-Needle Aspiration
If the veterinarian finds that the lymph nodes are enlarged, they may perform a fine-needle aspiration (FNA). This procedure involves inserting a small needle into the lymph node to collect a sample of cells. This is typically a quick process and can often be done without anesthetic.
Step 3: Cytology
The collected sample is then examined under a microscope, a process known as cytology. This allows the veterinarian to identify the types of cells present in the lymph node, which can help diagnose various conditions such as infection, inflammation, or cancer.
Step 4: Blood Tests
The vet may also recommend blood tests. These can provide information about your dog’s overall health and can help identify infections, immune-mediated diseases, or other potential causes of lymph node enlargement.
Step 5: Additional Diagnostic Tests
Depending on the results of the initial tests, additional diagnostic procedures may be necessary. This can include imaging tests like X-rays or ultrasounds to examine the internal structure of the lymph nodes and surrounding areas, or more invasive procedures like a biopsy, where a larger sample of tissue is taken for examination.
Step 6: Review of Diagnostic Results
Once all tests have been completed, the veterinarian will review the results to make a diagnosis. They will then discuss these findings with you, along with potential treatment options and prognosis.

Treatment of Enlarged Prescapular Lymph Nodes In Dogs
The treatment for prescapular lymph nodes in dogs will largely depend on the underlying cause of the swelling.
Antibiotics or Antifungal Treatment
If the lymph nodes are enlarged due to a bacterial or fungal infection, the infection will need to be treated with antibiotics or antifungal medication.
Chemotherapy or Radiation Therapy
In cases where the swollen lymph nodes are caused by cancer, more aggressive treatment options such as chemotherapy or radiation therapy may be recommended.
Prednisone, a type of corticosteroid, is often used to treat lymphoma in dogs. While it does not cure the disease, it can temporarily reduce clinical signs and buy the pet some time. Approximately 50% to 70% of dogs will respond to Prednisone alone to some extent and see at least a partial reduction in lymph node size.
In some cases, the veterinarian may recommend the surgical removal of the lymph nodes. Techniques for removal include sharp or blunt dissection or careful electrocautery, aiming to stay immediately outside the lymph node capsule.
