I must ask how would a dog's saliva get in your system
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.
No, dog saliva is not antiseptic.
I know cat saliva does. I think it is safe to assume dog saliva does too.
as long as possible
Not unless you make out with a dog. But other than that, why would you mix the two?
It can inhibit the growth of some bacteria but dog saliva contains bacteria.
Saliva
You will poison
Dog drool is saliva, just luck human saliva. This means that the smell of the drool depends on what the dog ate and which bacteria live within the dog's mouth.
Simple, you get a measuring cup, possibly from your kitchen, to measure liquids. Take the amount of saliva from dog (do not force dog to give saliva, that is cruel) and measure the amount from the tool. Dog saliva is a needed ingredient in many food dishes, including many seafood dishes.
A dog has saliva around its mouth to help with digestion and to keep its mouth moist. Saliva also helps to break down food and make it easier to swallow.
Yes as long as the male dog is not fixed
