How to Know if Your Dog Has Swollen Glands
As a responsible pet owner, being aware of your dog’s health is vital, including noticing signs of medical issues such as swollen glands. Swollen glands, or more accurately, enlarged lymph nodes, can be an early sign of an underlying health condition.
What Are Dog Lymph Nodes?
Lymph nodes are small, bean-shaped structures that form part of your dog’s immune system. They help filter harmful substances and fight infections. Normal lymph nodes are usually not noticeable, but when they become swollen, they can be a sign of infection, inflammation, or more serious conditions.
Common Locations of Lymph Nodes in Dogs
You can feel your dog’s lymph nodes in several areas, including:
- Submandibular – under the jaw near the neck
- Prescapular – in front of the shoulders
- Axillary – in the armpits
- Inguinal – in the groin area
- Popliteal – behind the knees
Signs Your Dog May Have Swollen Glands
Look out for the following symptoms if you suspect swollen glands:
- Visible lumps or swelling under the skin around the lymph node areas
- Lethargy or unusual tiredness
- Loss of appetite
- Fever or signs of discomfort
- Coughing, especially if thoracic lymph nodes are affected
Common Causes of Swollen Lymph Nodes in Dogs
- Infections – Bacterial, viral, or fungal infections may cause lymph node enlargement.
- Inflammation – Injury or immune-mediated diseases can lead to swollen glands.
- Cancer – Lymphoma or metastasis from other cancers can present with lymphadenopathy.
- Allergic reactions – In some cases, allergies may cause lymph nodes to swell.
How to Check Your Dog for Swollen Glands
Here’s a step-by-step guide to inspect your dog at home:
- Gently palpate under the jaw and around the neck for any unusual lumps.
- Feel around the shoulders and armpits – swelling can feel firm or rubbery.
- Check behind your dog’s knees and in the groin area.
- Compare both sides of the body for symmetry.
- Note any signs of pain or discomfort while touching these areas.
Important: If you find swelling or your dog shows other signs of illness, consult your veterinarian promptly.
Diagnosis and Treatment
When you consult a vet, they may perform:
- Physical examination
- Fine-needle aspiration or biopsy of the lymph node
- Blood tests to identify infections or immune diseases
- Imaging such as X-rays or ultrasounds
Treatment depends on the cause and may include antibiotics, anti-inflammatory medications, or cancer therapies. Prompt diagnosis is key to managing the underlying condition effectively.
When to Seek Veterinary Help
You should visit a veterinarian if your dog exhibits any of the following:
- Persistent or growing lumps
- Signs of illness or discomfort
- Loss of appetite or weight loss
- Behavioral changes or fatigue
Conclusion
Being proactive in checking for swollen glands in dogs helps catch potential illnesses early. Regular observation, combined with professional veterinary care, ensures your furry companion leads a healthy and happy life.
