Excessive drooling in dogs can have various causes, and sudden onset of excessive drooling may indicate an underlying issue. Here are some possible reasons why a dog may start drooling excessively:
-
Dental problems: Dental issues such as gum disease, tooth decay, oral infections, or foreign objects lodged in the mouth can cause excessive drooling. Dogs may drool more to help alleviate discomfort or pain associated with their dental condition.
-
Nausea or gastrointestinal issues: Dogs may drool excessively if they are feeling nauseous or have an upset stomach. Gastrointestinal problems, such as gastritis, pancreatitis, or ingestion of toxic substances, can trigger excessive drooling.
-
Oral irritation or injury: Any injury or irritation to the mouth, tongue, or throat can lead to increased drooling. This could be due to burns from hot substances, oral trauma, or the ingestion of irritants or caustic substances.
-
Heatstroke: Dogs regulate their body temperature by panting, but in extreme heat or when they are unable to cool down adequately, they may develop heatstroke. Excessive drooling can be a symptom of heatstroke, accompanied by other signs such as panting, weakness, vomiting, and collapse.
-
Anxiety or stress: Dogs may drool excessively when they are anxious, stressed, or experiencing fear. This can occur in response to various triggers, such as loud noises, unfamiliar environments, or separation anxiety.
-
Oral foreign body: If a dog has ingested a foreign object that is stuck in the mouth or throat, it can cause drooling along with other signs like gagging, retching, or difficulty swallowing.
- Poisoning: Certain toxins or poisonous substances can cause excessive drooling as a symptom. Examples include ingestion of toxic plants, chemicals, or medications.
If your dog is drooling excessively and it is accompanied by other concerning symptoms, such as lethargy, vomiting, difficulty breathing, or changes in behavior, it's crucial to consult with a veterinarian for a proper diagnosis and appropriate treatment.
