Dog Drooling Excessively Causes Concerns And When To Worry

Drooling is a normal part of canine behavior—especially in breeds like Saint Bernards, Newfoundlands, and Bulldogs known for their loose jowls. But when drool becomes excessive, persistent, or sudden, it may point to an underlying issue. While occasional salivation after exercise or during mealtime anticipation is expected, owners should pay attention when the pattern changes. Understanding the causes behind excessive drooling and knowing when to seek veterinary care can make a critical difference in your dog’s health.

Common Causes of Excessive Drooling

Saliva plays a vital role in digestion, oral hygiene, and temperature regulation in dogs. However, excessive production or visible drooling (also called ptyalism) often stems from physical discomfort, illness, or environmental triggers. Some of the most frequent causes include:

• Dental disease: Periodontal infections, broken teeth, or gum inflammation can irritate the mouth and trigger excess saliva.
• Foreign objects: Sticks, bones, or toys lodged in the mouth or throat can cause pain and drooling.
• Nausea or gastrointestinal upset: Motion sickness, dietary indiscretion, or ingestion of toxins often lead to hypersalivation.
• Heat exhaustion: Overheating increases panting and drooling as dogs attempt to cool down.
• Poisonous substances: Ingestion of household chemicals, toxic plants (like sago palm), or certain human foods (e.g., chocolate, xylitol) can induce drooling.
• Oral tumors: Growths in the mouth or throat may obstruct normal swallowing and stimulate saliva production.
• Kennel cough or respiratory infections: These conditions sometimes come with throat irritation and increased salivation.

Tip: Regularly inspect your dog’s mouth for redness, swelling, tartar buildup, or foreign material—early detection prevents complications.

When to Be Concerned: Red Flags to Watch For

Not all drooling requires immediate concern, but certain signs indicate a need for prompt veterinary evaluation. If your dog shows any of the following symptoms alongside excessive drooling, contact your vet immediately:

• Sudden onset of drooling without obvious cause
• Blood-tinged or discolored saliva
• Difficulty swallowing or refusal to eat or drink
• Pawing at the mouth or face
• Vomiting, diarrhea, or lethargy
• Bad breath (halitosis), which may suggest dental infection
• Tremors, seizures, or uncoordinated movement (potential poisoning)
• Swelling around the face or neck

“Sudden, unexplained drooling is one of the top reasons owners bring pets in for emergency visits. It’s often the first visible sign of something serious.” — Dr. Lena Patel, DVM, Emergency Veterinary Specialist

Step-by-Step Guide: What to Do If Your Dog Is Drooling Excessively

If you notice abnormal drooling, follow these steps to assess the situation and determine whether professional help is needed:

1. Stay calm and observe: Note when the drooling started, its severity, and any accompanying behaviors.
2. Check the mouth: Gently open your dog’s jaws to look for cuts, ulcers, broken teeth, or stuck objects. Use caution—painful animals may snap.
3. Review recent activities: Did your dog chew on something unusual? Was he exposed to cleaning products or toxic plants?
4. Monitor for other symptoms: Track appetite, energy levels, vomiting, or difficulty breathing.
5. Contact your veterinarian: Describe the symptoms clearly. If possible, record a short video of the drooling episode.
6. Seek emergency care if needed: If you suspect poisoning, obstruction, or neurological involvement, go to the nearest emergency clinic.

Do’s and Don’ts: Managing Excessive Drooling at Home

Do’s	Don’ts
Inspect your dog’s mouth carefully	Forcefully remove a deeply lodged object
Offer fresh water to rinse the mouth	Ignore drooling that lasts more than a few hours
Keep your dog calm and cool	Give human medications without veterinary approval
Use a clean cloth to wipe drool gently	Delay vet care if your dog seems distressed
Store toxic substances out of reach	Assume it’s “just normal” if behavior has changed

Real-Life Example: Bella the Labrador’s Close Call

Bella, a 5-year-old chocolate Lab, began drooling uncontrollably one evening after a backyard play session. Her owner initially assumed it was due to excitement over dinner. But when Bella refused to eat, pawed at her mouth, and started retching, concern grew. A quick check revealed a small piece of corn cob wedged between her molars. Though seemingly minor, the object caused significant irritation and prevented normal swallowing. After removal by the vet and a course of antibiotics for secondary infection, Bella recovered fully. This case highlights how even benign-seeming items can lead to serious complications if not addressed promptly.

Tip: Avoid giving dogs access to corn cobs, cooked bones, or stringy meats—common culprits in oral obstructions.

Prevention Checklist: Reducing Risk of Excessive Drooling

Proactive care can minimize many causes of abnormal salivation. Use this checklist to keep your dog healthy:

• ✅ Schedule biannual dental checkups with your veterinarian
• ✅ Brush your dog’s teeth regularly using pet-safe toothpaste
• ✅ Provide safe, size-appropriate chew toys
• ✅ Keep toxic substances (cleaners, pesticides, medications) securely stored
• ✅ Supervise outdoor time to prevent scavenging
• ✅ Monitor eating habits and avoid table scraps
• ✅ Know the signs of heatstroke and never leave your dog in a hot car

Frequently Asked Questions

Is it normal for my dog to drool more in the car?

Yes, motion sickness is common in dogs and often presents with drooling, lip licking, and vomiting. If travel-related, consider gradual acclimation, fasting before trips, or consulting your vet about anti-nausea medication.

Can anxiety cause my dog to drool?

Absolutely. Stressful situations—such as thunderstorms, fireworks, or vet visits—can trigger autonomic responses including excessive salivation. Behavioral conditioning and calming aids (like pheromone diffusers) may help reduce episodes.

My dog suddenly started drooling overnight—should I wait until morning?

No. Sudden drooling without explanation warrants same-day evaluation. Delaying could risk worsening conditions like infections, obstructions, or poisoning.

Conclusion: Stay Alert, Act Early

While some drooling is natural, dramatic changes in your dog’s salivation patterns deserve attention. The key lies in recognizing what’s typical for your pet and acting decisively when something feels off. Many causes of excessive drooling are treatable—if caught early. Routine dental care, a safe environment, and awareness of toxic hazards go a long way in prevention. But when in doubt, always err on the side of caution and consult your veterinarian. Your vigilance today could prevent a medical crisis tomorrow.
