A Difference between Drooling and Foaming

Before we go into the practice of salivating at the mouth for dogs, it’s essential to know the difference between drooling and foaming.

Although some drooling could be natural for our dogs, it usually is a cause for concern when a dog’s drool turns to foam.

What is it that sets both foaming and drooling apart?

While drooling and fluttering may refer to different things, foaming in the mouth can result from drooling.

Foaming is the effect of air contact with saliva, typically when the dog is panting.

The motion of air inside a dog’s mouth makes their saliva foam, which can lead to the appearance of foaming outside the mouth.

Let’s dive into the visual distinctions between salivating and foaming to give you better visuals.

What is the reason why Mouth Foaming is a recurring occurrence in dogs?

Foaming at the mouth can be a minor issue that can lead to an even more severe problem. Some of the causes are:


If your dog is running or playing for long periods, it is prone to losing a lot of energy. Overexertion may cause your dog to make his mouth water because of breathing and make his saliva appear foamy.

Heat Stroke

If a dog’s temperature is alarmingly high, they could foam in their mouths, so they pant or collapse. The risk of heatstroke is higher in Brachycephalic dogs during warm weather.

Poisonous Substances

Dogs that ingest poisonous substances could foam up in the mouth. This is due to chemicals present in the toxic substances coming into contact with tissues within the mouth and jaw.

Oral Health Issues

Hypersalivation is a possibility if the dog suffers from oral health issues. The strain caused by abscesses, tumors, or mouth injuries could result in the mouth swell.


Dogs who experience stressful circumstances will pant and whine as well as bark. The mouth will become frothy because the intense drooling and deep breathing will create the mouth to foam.

Seizures are also a reason behind mouth foaming. The dog exhibits other signs and symptoms like shakes, fast panting, and agitation when a seizure is triggered. Mouth foaming can occur due to these reasons and the absence of swallowing.

Vomiting and Nausea

When a dog suffers from an uneasy stomach and is vomiting, its mouth may appear much more “watery” than usual due to nausea. Excessive drooling, stress, and excessive panting due to vomiting can trigger this condition.


The disease is also the cause of dogs foaming in areas around the mouth. This condition is often accompanied by agitated and unpredictable behavior. The foaming in the mouth isn’t just only temporary. It lasts an extended period.

Preventing foaming at the mouth

If your dog suffers from an issue with his health and the treatment options are sufficient to allow him to recover fully, the problem could go away. It is vital to keep your dog from developing any more health problems that can be avoided, such as ingesting harmful materials. Elimination of all toxic substances or plants from your property and home can stop your dog from eating these harmful substances.

Make sure your dog is current with their Rabies vaccination.

Ensure your pet is in shaded areas if it is in the heat. Also, don’t excessively exercise them.
