It’s part of the charm for some breeds, but excessive dog drool, or slobbering, can be a messy reality for pet owners. While some drooling is perfectly normal, especially when food is around, there are times when excessive slobbering can signal an underlying health issue. Understanding why your dog is drooling so much is the first step in ensuring their wellbeing.
The Role of Saliva: More Than Just Drool
Dog saliva is a complex fluid, far more than just water. Around 98% water, it’s also packed with essential components like antibacterial compounds, enzymes, and electrolytes. Produced by glands near the jaw, saliva travels through ducts into the mouth, playing a vital role in your dog’s health.
One key enzyme in saliva is amylase, which kickstarts the digestive process right in the mouth. Amylase begins breaking down food as your dog chews, while saliva also moistens food, making it easier to form a bolus for swallowing. Beyond digestion, saliva keeps the mouth comfortable and enhances the taste of food.
Saliva is also a natural defense for your dog’s teeth. By washing away food particles, it helps prevent cavities and tooth decay. Its antibacterial properties even combat germs that cause bad breath. However, when saliva production becomes excessive, it can overflow, leading to noticeable drooling. While saliva is beneficial, too much of it can indicate a problem.
Breed-Specific Drooling: Are Some Dogs Just Naturally Slobbery?
Occasional drooling is normal for all dogs. However, certain breeds are known for producing more saliva and are therefore more prone to drooling. These breeds often include:
- St. Bernards
- Bulldogs
- Bloodhounds
- Mastiffs
- Newfoundlands
- Bernese Mountain Dogs
For owners of these breeds, some level of drooling is simply part of daily life. However, even in these breeds, it’s important to be aware of your dog’s typical drooling level to identify when something might be amiss. An increase in drooling, even in a predisposed breed, warrants attention.
Decoding the Drool: Common Causes of Excessive Slobbering in Dogs
Numerous factors can trigger excessive drooling in dogs. Let’s explore some of the most common reasons:
The Enticing Smell of Food
Dogs possess an incredibly sensitive sense of smell, boasting over 200 million scent receptors. This heightened olfactory ability means their salivary glands can go into overdrive at the mere whiff of food. Even just opening a bag of dog food can be enough to set off a drooling response in anticipation of a tasty meal.
Nausea and Gastrointestinal Upset
Just like humans, dogs drool when they feel nauseous. Various conditions can induce nausea, including:
- Gastrointestinal (GI) issues: Indigestion, infections, or dietary indiscretions can upset your dog’s stomach.
- Vestibular (balance) issues: Inner ear problems affecting balance can lead to nausea and drooling.
- Motion sickness: Car rides can cause motion sickness in some dogs, resulting in drooling and sometimes vomiting.
If your dog is suddenly drooling excessively and showing other signs of nausea like lip licking, restlessness, or vomiting, it’s important to consider potential causes of stomach upset.
Physical Anatomy: Mouth Shape Matters
For some breeds, excessive drooling is simply a consequence of their physical conformation. Giant breeds, particularly those with loose, saggy lips and jowls, are prime examples. These facial features don’t effectively contain saliva, allowing it to drip out more easily. Breeds like Bloodhounds, Mastiffs, St. Bernards, and Newfoundlands are particularly prone to this type of drooling due to their anatomy.
Dental Problems: Oral Health and Drooling
Despite saliva’s protective qualities, dogs are still susceptible to dental issues. Tartar buildup can trap bacteria, leading to gingivitis (gum inflammation) and periodontitis (gum disease). Inflamed or infected gums become painful, and teeth can loosen as bone tissue deteriorates. Dental problems like these, including tooth fractures or abscesses, often trigger excessive salivation as the mouth attempts to flush out irritants and address the pain.
Oral Injuries and Growths: From Minor to Serious
Injuries within the mouth can also lead to increased drooling. These can include:
- Abrasions: Chewing on hard objects can cause scrapes and irritation.
- Ulcers, cuts, and burns: These injuries can be caused by various factors, including ingestion of irritating substances.
- Growths: Lumps or bumps in the mouth, whether benign warts or cancerous tumors, can irritate the salivary glands and cause drooling. Even seemingly harmless growths can sometimes lead to increased saliva production.
Ingestion of Toxins: A Medical Emergency
If your dog has ingested something poisonous, excessive drooling is a common and critical symptom. Other signs of poisoning can include:
- Agitation or distress
- Tremors
- Convulsions
- Vomiting
- Seizures
- Nosebleeds
- Staggering
If you suspect your dog has ingested a toxin, immediate veterinary attention is crucial. Contact your veterinarian or a local animal emergency hospital without delay.
Excitement and Anxiety: Emotional Drooling
Drooling isn’t always linked to physical issues. Emotional states like excitement or anxiety can also trigger increased saliva production. This is why dogs sometimes seem to “slobber all over you” when they are happy to see you or are anticipating a walk or playtime. Similarly, dogs who are stressed or anxious may also drool more than usual.

Is Your Dog’s Drooling Normal or a Cause for Concern?
While some drooling is normal, it’s crucial to recognize when it becomes excessive or is accompanied by other symptoms. If you notice any of the following alongside increased drooling, it’s essential to schedule a veterinary appointment as soon as possible:
Changes in Appetite or Eating Habits
If excessive drooling is linked to a health problem, you may observe changes in your dog’s eating habits. A decreased appetite or reluctance to eat dry kibble, especially in dogs who usually enjoy it, can be a red flag. They might hesitate to eat, drop food, chew awkwardly, or prefer soft, moistened food if they have oral pain. While nausea-related drooling may be temporary, drooling caused by injuries, growths, or foreign objects will persist until the underlying issue is resolved.
Behavioral Changes
Pain can significantly alter a dog’s behavior. Even the gentlest dog might become irritable or aggressive when experiencing oral pain. Conversely, some dogs may become withdrawn, reclusive, or unusually quiet when they are unwell.
Pawing at the Face or Mouth
A dog experiencing oral discomfort may paw at their face or rub their muzzle on the floor in an attempt to relieve the pain. Dogs with esophageal or stomach problems causing drooling might also gulp frequently or extend their necks when swallowing food or water.
Managing and Addressing Excessive Drooling
The approach to managing excessive drooling depends entirely on the underlying cause. Potential treatments and management strategies include:
- Emergency veterinary care: Crucial for toxin ingestion or severe medical conditions.
- Dental cleaning or extractions: To address dental disease and related pain.
- Treatment for GI issues: Medication and dietary changes to resolve nausea and stomach upset.
- Removal of irritants or foreign objects: Addressing oral injuries or blockages.
- Medication for nausea: To manage motion sickness or other causes of nausea.
For drooling related to behavior, strategies might include calming techniques for excited or anxious dogs. Creating a quiet space for your dog during social gatherings or using calming aids can be helpful. Keeping towels handy in drool-prone situations, like during meal preparation, is also a practical tip.
If your dog’s drooling is primarily due to their breed and mouth shape, management focuses on minimizing the mess. Trendy bandanas can be a functional and fashionable way to catch slobber. Ultimately, embracing the quirks of drooly breeds, while ensuring their comfort and health, is part of the joy of pet ownership.

Emergency? If you suspect your dog has ingested a toxin or is experiencing a drooling emergency, contact your veterinarian or a 24/7 emergency animal hospital immediately.
