Lymphadenitis in dogs is an inflammation of the lymph nodes. Inside of them are immune blood cells that are directly involved in protecting the body against various infections.
They are also the first barrier that delays bacteria, dust particles, viruses, and also small foreign bodies. Therefore, lymph nodes often take on the first stroke of inflammation and lymphadenitis is expressed in an increase in the volume of those lymph nodes that lie next to the organs and tissues in which inflammation occurs.
In addition, the disease can exist independently, flowing acutely or chronically. The causes of lymphadenitis can be different and treatment and prognosis depend on them in general.
Forms and symptoms
Lymphadenitis in dogs can be specific and non-specific and can be acute or chronic. Specific lymphadenitis is a symptom of a specific disease, for example,
- the plague
- actinomycosis and others.
Such lymphadenitis is diagnosed and treated depending on the underlying disease. The nonspecific form has no particular signs that would associate the disease with the pathogen. As a rule, it is caused by streptococcus or staphylococcus.
Acute nonspecific lymphadenitis begins with an increase and tenderness of the lymph nodes, weakness, headache, fever, malaise.
Often, acute lymphadenitis occurs when subsiding of the main inflammatory process. In catarrhal lymphadenitis, the dog develops pain in the area of the regional lymph nodes. If the process progresses and the inflammation turns into a purulent form, the pain becomes sharp, the skin over the lymph nodes reddens.
Lymph nodes merge with the surrounding tissues and between themselves, become stationary. The body temperature of the animal rises to 42 degrees, tachycardia, chills, weakness appear. Purulent process may spread to the cellular tissue spaces. Chronic nonspecific lymphadenitis occurs as a result of exposure to microbial flora with sluggish inflammatory diseases:
- inflammatory diseases of the teeth,
- chronic tonsillitis.
It can also be the outcome of acute lymphadenitis, which has passed into a prolonged chronic course. In the chronic course of the disease, the purulent form is extremely rare. The main symptoms are swollen and swollen lymph nodes. It is practically not painful and is not soldered to the surrounding tissues and between them.
Treatment of lymphadenitis in dogs
If an enlarged lymph node is found in a dog (under the ears, behind the jaw, at the base of the neck or in the armpits of the front paws), it is necessary to urgently contact a veterinarian and pass a blood test. With a good general condition of the dog, the doctor prescribes antibiotics and a heating pad at the site of inflammation of the node.
However, the lymph nodes cannot be heated if the body temperature is elevated. In such a situation, appointed substances that stimulate the immune system and antibiotics. For suppuration of the inflamed lymph nodes, bandages with Vishnevsky ointment are used.
Also, nodes can be surgically opened and drainage can be provided to drain the contents. Assigned and vitamins to support the body. In cases where the body temperature has not decreased after treatment with antibiotics and the lymph nodes are inflamed, the doctor may suspect an oncology that is starting.
In such a situation, treatment with hormones is prescribed, and after delivery of tests and chemotherapy. In acute, as well as in chronic nonspecific lymphadenitis, treatment is directly dependent on the stage of the process. With the initial forms, UHF-therapy and active treatment of the main focus of infection are sufficient. However, destructive forms of lymphadenitis can lead to death of lymph nodes, which leads to a violation of lymphatic drainage.
In order to prevent the need to timely treat all infectious diseases and increase the body's resistance, strengthening it. Treatment of specific lymphadenitis is carried out in accordance with the underlying disease. For a dog owner, it is important to understand that an enlarged lymph node is a sign that an infection is in the animal's body. In this case, the immune system is already struggling with it. Because the owner’s duty is to deliver the animal to the doctor as soon as possible to help the body cope with the infection.
