Excessive slobbering in dogs can be alarming for pet owners, as it often indicates an underlying health or behavioral issue.
While some dogs naturally drool more than others, a sudden increase in salivation may signal discomfort.
We outline the common reasons why a dog may excessively slobber, what you can do at home, and when to seek veterinary help.
Dog Excessively Slobbering— Why It Happens
A dog excessively slobbering is usually caused by a combination of factors, ranging from normal breed tendencies to medical issues.
Some dogs naturally produce more saliva, particularly breeds like Saint Bernards, Bloodhounds, and Mastiffs. However, sudden or persistent drooling can be a sign of dental problems, nausea, infections, toxins, or other health concerns that require attention.
Environmental factors, excitement, or stress can also trigger excessive drooling, making it important to observe the context in which your dog slobbers.
Dog Excessively Slobbering: Common Causes
Dental Disease
Dental issues are a leading cause of excessive drooling in dogs. Infections, periodontal disease, or oral injuries can cause pain, prompting a dog to salivate more.
You may notice bad breath, bleeding gums, or difficulty eating. If untreated, dental disease can spread bacteria to other organs, making early intervention crucial.

Nausea and Digestive Upset
Dogs often drool when feeling nauseated, especially before vomiting. Motion sickness, dietary indiscretion, or gastrointestinal upset can trigger increased salivation.
Signs include lip licking, pacing, or retching, indicating your dog is uncomfortable. Persistent nausea may require veterinary evaluation to identify underlying causes like pancreatitis, infections, or gastrointestinal blockages.
Oral Injuries or Foreign Objects
A foreign object stuck in the mouth, gums, or throat can lead to sudden and excessive drooling.
Broken teeth, cuts, or abrasions may also cause pain-related salivation. You might observe pawing at the mouth, reluctance to eat, or visible swelling.
Immediate attention is important, as foreign objects can obstruct the airway or cause severe infection.
Toxins or Poisoning
Ingesting toxic substances, plants, or chemicals can result in dramatic increases in drooling. Symptoms may include vomiting, lethargy, trembling, or behavioral changes.
Prompt veterinary care is essential, as many toxins can be life-threatening. Avoiding common hazards and monitoring your dog’s environment helps prevent accidental poisoning.
Heatstroke or Overheating
Excessive panting accompanied by drooling can indicate heatstroke. Dogs regulate body temperature through saliva evaporation and panting, making overheating a serious concern.
Signs include rapid breathing, red gums, weakness, and vomiting. Quick intervention, including cooling measures and veterinary attention, is necessary to prevent organ damage.
Anxiety or Stress
Behavioral triggers such as anxiety or stress may cause drooling even in otherwise healthy dogs.
Situations like thunderstorms, separation anxiety, or car rides can induce salivation. Other signs include pacing, whining, trembling, or hiding.
Behavioral management and training can reduce stress-related drooling, while persistent cases may benefit from professional guidance.
What to Do If Your Dog Is Excessively Slobbering
If your dog is slobbering more than usual, start by observing the context. Note whether the drooling is associated with excitement, stress, or after meals.
Ensuring your dog has clean water available can help prevent dehydration, especially if vomiting or nausea is present.
Maintain good oral hygiene by brushing your dog’s teeth regularly and scheduling professional dental cleanings as recommended by your veterinarian.
If foreign objects or oral injuries are suspected, check the mouth carefully and avoid using fingers in ways that could be harmful; seek veterinary evaluation for safe removal or treatment.
Dietary management can reduce gastrointestinal upset; avoid giving table scraps or unknown foods, and gradually introduce any diet changes. If anxiety-related drooling is suspected, provide a calm environment and consider enrichment activities to distract and soothe your dog.
Monitoring your dog’s overall health, including appetite, energy levels, and bowel movements, can help identify patterns and early signs of illness. Keeping a log of drooling episodes can be useful when discussing concerns with your veterinarian.
When to Call or Visit Your Vet
Excessive drooling accompanied by vomiting, lethargy, trouble breathing, swelling, or obvious pain requires immediate veterinary attention. Sudden increases in drooling after possible toxin ingestion or suspected foreign object ingestion are emergencies.
Persistent drooling without an obvious behavioral or environmental cause should also be evaluated.
Dental infections, oral injuries, and underlying health conditions may not be visible but can seriously affect your dog’s well-being if left untreated. Your veterinarian can perform oral exams, bloodwork, imaging, or other diagnostic tests to determine the cause and appropriate treatment.

Key Takeaway
Excessive slobbering in dogs can range from a normal breed characteristic to a warning sign of underlying health issues.
Observing the context, checking for other symptoms, and maintaining dental hygiene are key steps for pet owners. Behavioral triggers, oral injuries, nausea, toxins, and heatstroke are common causes that require careful attention.
Early veterinary intervention is important when drooling is sudden, severe, or accompanied by other concerning signs.
By monitoring your dog’s health, providing a safe environment, and seeking timely medical advice, you can ensure your dog stays comfortable, healthy, and happy.
