Why Dogs Always Drool: Unveiling the Reasons!
Did you know that 99% of a dog's saliva is water, with the remaining 1% consisting of minerals and enzymes? When dogs lick their paws, bottoms, or wounds, the lysozyme in their saliva can provide some level of antibacterial protection. Moreover, saliva helps to moisten food, enhancing its taste and making it easier to swallow.
Why do dogs sometimes seem to drool excessively?
Genetic Factors
Some large dog breeds, like the Newfoundland and St. Bernard, have larger heads and mouths, which can lead to poor closure and, as a result, frequent drooling. This is a physiological issue that often requires the patience of their owners to help clean up the mess.
Thermoregulation
In the heat of summer, humans cool down through sweating, and dogs do the same, albeit through their tongues. Since dogs have fewer sweat glands, they may drool more frequently during hot weather to expel excess body heat. This is a relatively normal occurrence, so it's important to ensure your dog stays hydrated and to use physical cooling methods to prevent overheating.
Teething
Many puppies experience an increase in drooling during specific periods, particularly when teething. The growth of new teeth stimulates the salivary glands, leading to excessive saliva production. Combined with an underdeveloped esophagus and swallowing inexperience, this can cause drool to run down their chins.
Emotional Excitement
Dogs may involuntarily drool when they are extremely happy, scared, or angry. This could be due to seeing their owner, encountering food, facing a threat, or having their toys taken away. These emotional fluctuations trigger an instinctive conditioned reflex.
Illness
Lastly, if your dog is drooling excessively, it's crucial to take this seriously. Issues like tartar, tooth decay, and gum inflammation can cause pain, prompting the salivary glands to produce more saliva. Regular teeth cleaning can help alleviate this. If drooling persists, consider other possibilities such as mouth ulcers or lumps. In such cases, it's best to consult a veterinarian for a proper examination.
