Dogs with a healthy microbiome have a robust immune system. Since most of a dog's immune cells are distributed in the gut, an imbalance in gut microbiota can lead to various health issues such as compromised immunity, skin disorders, and diabetes in pets.

Diseases resulting from weakened immunity may temporarily improve with treatment but are prone to relapse, with symptoms worsening or evolving into more serious conditions, warranting caution. If there are inherent issues with the immune system or if inflammatory conditions persist due to chronic illnesses that compromise immunity, consider managing gut health through microbiome testing to boost your dog's immune system. Additionally, consistently provide a nutritious diet and supplement with probiotics or other supplements beneficial for gut health to enhance immunity in your dog.
