Lymph nodes in dogs belong to the immune organs of the body and are located in various parts of the body such as the hair under the chin, abdomen, chest and armpits, and the roots of the thighs. When a lesion or inflammatory reaction occurs in one part of the body, the lymph nodes near it will swell. Swollen lymph nodes are a symptom, not a cause of the disease. The most common cause is inflammation of the limb that causes the lymph nodes draining that area to swell. This condition eliminates the inflammation of the limb and the lymph nodes will naturally improve. Secondly, due to the age of the dog, lymphoma or tumor metastasis to the lymph nodes cannot be ruled out. Pathological changes in lymph nodes can be divided into acute or chronic swelling, and some will show a tendency to septicemia. 1. Acute swelling: usually shows obvious enlargement, smooth surface, and will be accompanied by obvious heat and pain reactions. Acute swelling of lymph nodes is more commonly associated with acute infection of surrounding tissues and organs. 2. Chronic swelling: usually presents swelling, hard nodes, uneven surface, no heat, pain and other related reactions, and most of them have adhesions with surrounding tissues and are more difficult to move. Chronic swelling of lymph nodes can be seen in the early stages of canine lymph node leukemia as chronic swelling without heat or pain in the surface lymph nodes. In addition, chronic swelling of lymph nodes can also be seen in chronic infections and inflammation of the tissues and organs surrounding various lymph nodes.3. Lymph node suppuration: This problem presents with swelling, heat, and painful reactions along with significant fluctuations on palpation. To improve this problem, it may be necessary to perform puncture treatment, then aspirate the purulent contents inside and then perform anti-inflammatory treatment. However, puncture is not a casual procedure and requires some experience. If owners find that their dog has enlarged septic lymph nodes, they should not easily try to puncture them themselves to avoid causing unnecessary injury to the dog and increasing the severity of the problem. Examination of the underlying lymph nodes is of considerable importance in determining whether a dog is infected or diagnosing certain infectious diseases. The role of lymph nodes is mainly antibacterial, once the lymph nodes have problems, the dog will be vulnerable to some viruses. The examination of potential lymph nodes is of considerable importance in determining whether the dog is infected or diagnosing certain infectious diseases. The role of lymph nodes is mainly antibacterial, once the lymph nodes have problems, the dog will be vulnerable to some viruses. The usual lymph nodes that can be checked are the jaw lymph nodes, lymph nodes under the ear and around the throat, neck lymph nodes, shoulder lymph nodes, etc. The examination can be performed by visual inspection, palpation, and, if necessary, by puncture. When performing visual and palpation examinations of potential lymph nodes, the main things to look for are their location, hardness, shape, size, surface condition, sensitivity, and mobility. Once a dog has swollen lymph nodes, it is necessary to understand what the cause of the swelling is and then treat the dog in a targeted manner according to the specific situation. If it is infectious, it can be antibacterial and anti-inflammatory. If it is a malignant tumor, it needs to be combined with surgical treatment or even surgical removal, or the tumor can be treated with chemotherapy and or radiotherapy, etc. Note that older dogs aged 5-7 years old are most prone to lymphoma. The best way to prevent it is to take your dog for regular physical examinations and let professional doctors diagnose it for your dog so that it can be detected and treated as early as possible.
