Understanding Lymph Nodes and Their Roles
Lymph nodes, tiny bean-shaped structures, play a crucial role in your dog’s health. They function as your dog’s immune system’s first line of defense, trapping and eliminating harmful particles that enter the body. Unfortunately, these nodes can become swollen due to various reasons – from bacterial or viral infections to more serious conditions like cancer.
Recognizing Symptoms of Swollen Lymph Nodes
Recognizing the signs of swollen lymph nodes in your dog is the first step towards managing this condition. Here are some symptoms to watch out for:
- Swelling around the neck, shoulders, behind the knees, or under the jaw.
- Loss of appetite.
- Lethargy or unusual tiredness.
- Fever.

Understanding what could cause lymph nodes to swell helps you respond better to your dog’s condition. Here are some common causes:
- Infections: Bacterial or viral infections can cause inflamed lymph nodes.
- Immune Disorders: Certain immune disorders can trigger swelling.
- Cancer: Lymphoma, a type of cancer, can cause lymph nodes to swell.
