The immune system is one of the most important functions of any organism, including dogs. An immune system is a multi-faceted defense system against sickness. It enables a dog’s body to differentiate between germs, foreign substances and itself. When functioning properly, the immune system fights fungal infections, bacterial infections and illnesses, offers parasite protection, helps eliminate toxins from the body, and kills viruses. There are several ways to boost your dog’s immune system to help keep them healthy.
The immune system is adept at recognizing threats, and uses many layers to fight any infection that may present itself. The immune system is comprised of multiple cellular warriors, capable of recognizing pathogens that may attack. The immune system recognizes these pathogens by the proteins and chemicals they release. As a pathogen is recognized it is attacked, killed and consumed by the cells of the immune system. The immune system is capable of creating a memory of the pathogen to thwart a reinfection attempt.
