Excessive Dog Drooling: Nausea, Dental Issues or Poisoning?

Excessive drooling, medically known as ptyalism, can be a common occurrence in certain dog breeds like Saint Bernards, Newfoundlands, and Mastiffs. However, if your dog suddenly starts drooling excessively, especially if it’s a breed not prone to it, it’s crucial to investigate the underlying cause. While some causes are relatively benign, others can be serious and require immediate veterinary attention.

Nausea as a Trigger

One common reason for increased drooling is nausea. Just like humans, dogs can experience nausea due to various factors. Motion sickness during car rides is a frequent culprit. Ingesting something unpleasant, like spoiled food or garbage, can also trigger nausea and subsequent drooling. Certain medications can also cause nausea as a side effect. If you suspect nausea, observe your dog for other signs like vomiting, loss of appetite, or lethargy. If the drooling persists or is accompanied by other symptoms, consult your veterinarian.

Dental Problems and Oral Discomfort

Oral health plays a significant role in drool production. Dental issues, such as tooth decay, gingivitis, abscesses, or foreign objects lodged in the mouth, can irritate the gums and trigger excessive salivation. Inspect your dog’s mouth for any visible signs of redness, swelling, or discharge. A foul odor from the mouth can also indicate an underlying dental problem. Regular dental check-ups and proper oral hygiene, including brushing your dog’s teeth, can help prevent these issues.

The Threat of Poisoning

Perhaps the most concerning cause of excessive drooling is poisoning. Dogs are naturally curious and may ingest harmful substances, such as household cleaners, pesticides, certain plants, or human medications. Many toxins irritate the mouth and throat, causing increased salivation. Other symptoms of poisoning can include vomiting, diarrhea, tremors, seizures, difficulty breathing, and collapse. If you suspect your dog has ingested poison, immediately contact your veterinarian or the ASPCA Animal Poison Control Center. Prompt action is crucial in mitigating the effects of poisoning.

Other Potential Causes

Besides the main causes mentioned above, other factors can contribute to excessive drooling. These include:

Esophageal problems
Foreign bodies lodged in the throat
Nerve damage affecting salivation
Heatstroke
Certain medical conditions like liver disease or kidney failure

When to Seek Veterinary Care

While occasional drooling is normal, it’s important to seek veterinary attention if the drooling is sudden, excessive, or accompanied by any of the following symptoms:

Vomiting or diarrhea
Loss of appetite
Lethargy or weakness
Difficulty breathing
Seizures or tremors
Swelling of the face or neck
Signs of pain or discomfort

A veterinarian can perform a thorough examination to determine the underlying cause of the drooling and recommend appropriate treatment. Early diagnosis and intervention are essential for ensuring your dog’s health and well-being.
