Dr. Eisner notes that despite the cavity-preventing nature of dog saliva, periodontal disease will still occur without active prevention.
3. Open a third Petri dish. Inoculate it with exactly the same amount of staphylococcus epidermis bacteria that you used in step #1. Follow this by topping the bacteria with a small amount of dog saliva. Cover the dish and label it as sample A.
“It is not just what is carried in saliva,” he said. “Dogs spend half of their life with their noses in nasty corners or hovering over dog droppings so their muzzles are full of bacteria, viruses and germs of all sorts.”

Excessive Production of Saliva in Dogs | petMD
For many True Dog Lovers, there’s little more gratifying than the warm, soft, wet, loving licks from a canine friend. For many other people, dog saliva is seriously disgusting. Anyone who has had a whiff of putrid dog breath will go to great lengths to avoid a sloppy canine kiss. Actually, dog saliva has both advantages and disadvantages.Secretion of saliva is under control of the autonomic nervous system, which controls both the volume and type of saliva secreted. This is actually fairly interesting: a dog fed dry dog food produces saliva that is predominantly serous, while dogs on a meat diet secrete saliva with much more mucus. Parasympathetic stimulation from the brain, as was well demonstated by , results in greatly enhanced secretion, as well as increased blood flow to the salivary glands. For dogs, saliva is clearly beneficial. It contains a wide variety of proteins, enzymes, and antioxidants that provide protection and healing for the animal. According to some research, when dog saliva contacts skin, it creates nitric oxide, which protects the skin from infection by inhibiting bacterial growth. The enzyme lysozyme attacks the cell walls of certain bacteria. Proteins known as “histatins” and “nerve growth factor” expedite wound healing. Another protein, called tissue factor or thromboplastin, promotes blood clotting. All of this helps explain why dogs instinctively lick their wounds.Potent stimuli for increased salivation include the presence of food or irritating substances in the mouth, and thoughts of or the smell of food. Knowing that salivation is controlled by the brain will also help explain why many psychic stimuli also induce excessive salivation - for example, why some dogs salivate all over the house when it's thundering
