My dog has a swollen lymph node with spindle cells. Why is he sleepy?

Lymph nodes can become enlarged because they are draining an infection or inflammatory part of the body, because the lymphatic flow is being disrupted, or because of cancer in the nodes. I would discuss additional diagnostics with your vet, which may vary depending on which lymph nodes are involved. Aspiration of the affected lymph nodes is easy and can often be done without sedation. The samples are sent to a pathologist for review. X-rays of the chest and or abdomen may be indicated. Ultrasound of the abdomen may be needed. Dental cleaning and removal of diseased teeth if the lymph nodes are near the head.

Not necessarily as other disease processes can cause lymph node swelling. Every case is different and some dogs have mild lymphadenoapthy at diagnosis and others have significant lymphadenopathy. In general however reactive lymphadenopathy is usually more mild. If lymphadenopathy is suspected it is important to rule out other causes such as systemic diseases (tick borne, fungal, etc.) especially in a young dog in certain parts of the country (or with a travel history), allergic skin disease, etc. Ultimately needle sampling of the lymph nodes is an initial step but will not always diagnose all cases. There are also different types of lymphoma with different presentations, prognoses, and treatment approach. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

If witchy does have enlarged lymph nodes I would recommend doing a fine needle aspirate of the lymph node. This is where a vet places a small needle into the lymph node and looks at the cells under a microscope. This will tell you why the lymph node is enlarged. The most common causes are viral, bacterial, fungal, inflammation or cancer. I would not recommend using systemic strong anti-fungals without a diagnosis of fungal disease due to the affect on the liver. Hopefully between blood work ,x-rays and aspirate you can get a better idea of why Witchy is having big lymph nodes and start proper treatment.

Hello, sorry to hear about Giuseppe. Because the lymph node has decreased in size with antibiotics alone and the fact that only a single lymph node is enlarged, this is less likely consistent with lymphoma. Lymphoma typically affects multiple nodes and does not respond to antibiotics. Occasionally, active lymph nodes may remain slightly enlarged for a few days, or if the infection is not being completely treated then the lymph node may remain big. The best way to confirm if this lymph node has lymphoma or not, would be to obtain cytology with a with a needle aspirate to have a pathologist examine the cells. Cytology is generally a non-invasive procedure and could be done by your veterinarian. Hope this helps and best of luck.

If he has swollen lymph nodes then he could have an infection or possibly lymphoma. Your vet can run blood-work and aspirate the lymph node to determine why it is enlarged. If he has an infection than he would need an antibiotic to treat. If he has a problem with a disc in his back then he would also need an anti-inflammatory and pain medications.

Swollen lymph nodes can be a sign of cancer, tick borne diseases, or infections. The swollen nodes will not go back to normal until the underlying cause is addressed. I'd recommend seeing a veterinarian - a test for tick disease or sampling the lymph node with a needle might be recommended.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Luca! How old is Luca? He could have a swollen lymph node or salivary gland. A swollen salivary gland can indicate an infection, an obstruction or inflammation. An enlarged lymph node can indicate an infection or lymphoma (cancer) the swelling could also be a foreign body that migrated from him mouth (piece of stick for example). Luca needs an exam by a Vet, I would have him seen Monday. I wish you the best!
