Dog is Drooling Excessively All a Sudden – Top 3 Reasons Why

The sudden appearance of excessive drooling in dogs can be caused by a number of conditions, including dental and gastrointestinal problems. Here are a few common reasons that may explain excessive drooling in dogs.

1. Eating some toxic

Unexplained episodes of excessive drooling could be a result of the dog eating something that is toxic. Have a careful look around the house and see if any objects (small enough for the dog to eat) is missing or partially chewed. Houseplants, for example, are a common culprit of excessively drooling in dogs. Many common houseplants, such as aloe and dracaena, are toxic to dogs and topical exposure may be enough to cause sudden episodes of excessive drooling.

2. Dog is super anxious

Anxiety and stress can also lead to sudden bouts of excessive drooling. Was there a recent event that may have triggered an anxiety attack? It could be something like loud noises (e.g. thunder, fireworks) or the near-presence of a stranger or a foreign object. It may also be due to separation anxiety and the excessive drooling may happen just before you leave the house. Consider hypersalivation a part of the dog’s fight or flight response.

3. Sign of nausea

Sudden episodes of excessive salivation could also be due to nausea. There are many causes that can lead to canine nausea, including dietary changes, motion sickness, and diseases. When a dog is having nausea, their salivary glands go on overdrive and result in excessive production of saliva.

When should you worry about excessive drooling?

You should call the vet right away if the dog’s excessive drooling is accompanied by other worrying symptoms. It would also be a major worry if the dog is hypersalivating more and more often. Other worrying symptoms that may accompany hypersalivation include lethargy, excessive panting, and vomiting.
