Why Do Dogs Drool?

From an accidental dribble to a full-blown waterfall, there are lots of factors that can cause dogs to drool. The sight of food, even an excited game of fetch, and most of the time it is completely normal. We can’t deny that it’s pretty gross if you’re caught in the firing line, but our love for them makes up for it.

Why is My Dog Drooling?

Drooling, also known as hypersalivation, is a natural physiological response that helps dogs moisten and lubricate their mouths, aid in digestion, and regulate body temperature. Dogs have a larger and more active salivary gland than humans, which means they produce more saliva.

However, various factors can trigger increased drooling in dogs, including excitement, anticipation of food, dental issues, nausea, and even certain medical conditions.

Additionally, stress or anxiety can trigger excessive drooling in some dogs, particularly during situations such as car rides, visits to the veterinarian, or encounters with unfamiliar people or animals

Should I Be Concerned if My Dog Is Drooling?

While drooling is generally considered normal in dogs, excessive or sudden drooling may indicate an underlying problem that requires attention.

If your dog is drooling excessively, particularly if it's accompanied by other symptoms such as vomiting, diarrhoea, lethargy, or difficulty breathing, it could be a sign that something is wrong.

Conditions such as heatstroke, poisoning, oral injuries, or blockages in the airway can lead to severe drooling and require immediate veterinary attention. If you notice your dog drooling excessively and displaying other signs of distress, don't hesitate to seek emergency vet care.

Why Do Dogs Drool in Their Sleep?

Ever noticed your dog drooling while they're fast asleep? Don't worry; it's perfectly normal. When dogs enter the REM (rapid eye movement) stage of sleep, their muscles relax, including those responsible for controlling saliva production. 

As a result, some dogs may drool while they're dreaming or in deep sleep. While it may seem amusing or endearing, it's just another quirky behaviour that comes with being a dog.

Which Dog Breeds Drool the Most?

While all dogs drool to some extent, certain breeds are notorious for their slobbering tendencies. Breeds with loose, pendulous lips and jowls, such as Mastiffs, Saint Bernards, Bulldogs, and Bloodhounds, are more prone to drooling due to their anatomy.

Additionally, dogs with brachycephalic (short-nosed) breeds, such as Pugs and Boxers, may also experience increased drooling due to their unique facial structure.
