Salivation in dogs is a natural and important process controlled by the nervous system.
Here's how it works:
* Stimulation: The sight, smell, or even anticipation of food triggers the salivary glands in a dog's mouth. This stimulation can be from various sources, including:
* Food itself
* The sound of food preparation
* The presence of their owner at feeding time
* Nerves: These signals travel through nerves to the salivary glands.
* Secretion: The glands then release saliva, which flows through ducts into the dog's mouth.
* Purpose: Saliva serves several important purposes:
* Digestion: It contains enzymes that start breaking down food, making it easier for the dog to digest.
* Lubrication: Saliva helps food move smoothly down the esophagus and into the stomach.
* Oral hygiene: Saliva washes away food particles and bacteria, helping to keep the mouth clean.
Fun Fact:
Dogs can salivate in response to other stimuli besides food, such as stress, anxiety, or nausea.
