Antibodies
What are antibodies?
Antibodies, also known as immunoglobulins, are specialized proteins produced by the immune system to recognize and neutralize specific antigens such as bacteria, viruses and other pathogens. Each antibody is unique and directed against a specific antigen. They play a central role in the immune response by marking pathogens and facilitating their elimination. Antibodies are produced by B cells, a type of white blood cell, and are critical to the adaptive immune response, which provides specific and long-lasting protection against pathogens.
Benefits of antibodies for dogs
Protection from infection
The most obvious benefit of antibodies is their contribution to protection against infection. By directly neutralizing pathogens or marking them for destruction by other immune cells, antibodies are essential for the prevention and control of infectious diseases.
Immunological memory
One of the most fascinating properties of antibodies is their ability to form an immunological memory. After an initial exposure to an antigen, the immune system produces specific antibodies that enable a faster and stronger response in future encounters with the same antigen. This is the basis for the effectiveness of vaccinations, which rely on the induction of memory antibodies to provide long-term protection.
Support in diagnosis
Antibodies also play a crucial role in the diagnosis of various diseases. By measuring specific antibodies in the blood, veterinarians can determine whether a dog has had a particular infection or is immune to certain diseases. This is particularly important for monitoring vaccination status and early detection of diseases.
Possible disadvantages and risks
Autoimmune diseases
Despite their crucial role in protecting against disease, antibodies can sometimes mistakenly attack the body's own cells, leading to autoimmune diseases. Such diseases occur when the immune system recognizes the body's own cells as foreign and produces antibodies against them, which can lead to inflammation and tissue damage.
Allergic reactions
Antibodies are also involved in the development of allergic reactions. In some dogs, the immune system can react hypersensitively to harmless substances, such as certain foods or pollen, and produce antibodies that lead to inflammation, itching and other allergic symptoms.
Overreaction of the immune system
In rare cases, excessive production of antibodies or an excessive immune response can lead to damage to the body. For example, a strong immune response against certain viruses or bacteria can also damage healthy tissue and lead to inflammation and other complications.
Antibodies are an essential part of our dogs' immune system, playing a crucial role in protecting against disease. Not only do they provide direct protection against pathogens, but they also contribute to long-term immunity by forming an immunological memory. While antibodies have predominantly beneficial effects on health, in some cases they can also lead to autoimmune diseases or allergic reactions. Understanding the function and importance of antibodies can help dog owners navigate their pets' health care and make informed decisions regarding vaccinations and disease treatment. Ultimately, antibodies are a fascinating and vital part of the immune system that helps our dogs stay healthy and active.

If you notice any signs of hypersensitivity or poisoning in your dog, you should see your vet immediately. We are not a substitute for a vet, but we try to be as accurate as possible. Every dog reacts differently and we recommend you get a second opinion or consult your vet if in doubt.
Stay healthy and take good care of your four-legged friend!😊
