Saliva is part of the body's non-specific defence against foreign invaders. Bodily openings such as the mouth, ears and nose are protected by substances to limit access to the inner parts of the body. The nose contains fine hairs, the ears contain wax, and the mouth's defence is saliva. These all reduce the amount of bodily invasion by blocking and limiting foreign substances entering the body.

As such, saliva is an example of external defence of the immune system.

Hope that helped :)

Can a dogs saliva cure an allergy?

No, there are no healing properties in a dog's saliva. Allergies are caused by the body's immune system reacting inappropriately to a neutral protein molecule and treatment is based upon controlling the reaction in acute cases and retraining the immune system to not react in the long term. Exposure to a dog's saliva does neither of these, and may make allergies worse by stimulating the immune system to react to the saliva as well as whatever else it was reacting to.
