What is a Dog’s Immune System?

Components of the Immune System

A dog’s immune system is a sophisticated network of cells, tissues, and organs that work in unison to defend the body against harmful pathogens like bacteria, viruses, and parasites. The immune system has two main components:

• Innate Immune System: This is the body’s first line of defence, offering immediate, non-specific protection. It includes physical barriers like the skin and mucous membranes, as well as immune cells such as neutrophils and macrophages that swiftly identify and neutralise pathogens.
• Adaptive Immune System: This system is more specialised and is responsible for long-term immunity. It includes lymphocytes (B cells and T cells) that recognise specific pathogens and mount a targeted attack. B cells produce antibodies, while T cells destroy infected cells or assist other immune cells.

How the Immune System Functions

The immune system’s primary role is to protect the body from infections and diseases. It recognises foreign invaders and mounts a response to eliminate them. This involves complex interactions between various immune cells and signalling molecules like cytokines. The adaptive immune system’s memory function allows for a faster, more effective response upon re-exposure to previously encountered pathogens.

What Areas of Dog Health Does the Immune System Impact?

Digestive Health

A strong immune system is crucial for maintaining a healthy gut, preventing harmful bacterial overgrowth, and supporting a balanced microbiome.

Skin and Coat Health

The immune system helps prevent and manage skin infections and allergies. Proper immune function is essential for maintaining a healthy coat and preventing skin conditions.

Joint Health

The immune system regulates inflammation in the joints, helping to prevent conditions like arthritis. Dysregulated immune responses can lead to chronic inflammation and joint damage.

Mental Wellbeing

Research suggests that immune system imbalances can contribute to behavioural issues in dogs. Chronic inflammation may impact brain function, leading to mood disorders and cognitive dysfunction.

What is an Autoimmune Disease in Dogs?

Definition and Mechanism

Autoimmune diseases occur when the immune system mistakenly attacks the body’s own tissues, perceiving them as threats. This misguided attack can cause inflammation, tissue damage, and various health problems, depending on the organs and systems affected.

Common Autoimmune Diseases in Dogs

Some common autoimmune diseases in dogs include:

• Immune-Mediated Haemolytic Anaemia (IMHA)
