If people witness a dog’s foaming mouth, their first thought would be “rabies”. Most of the time it is not the scenario. In places where routine vaccination is practiced the rabies vaccination has helped bring the prevalence and spreading of canine rabies to the lowest degree. However, there are other causes that dogs may scream in the mouth, some of which require medical attention.


Common Reasons a Dog Foams at the Mouth

  • Dogs who play hard or exert lots of energy could make a mess of their mouths. If the dog is working lots of energy, they could be extremely salivating. When he puts in the energy or exerts himself the dog’s breathing speed increases and the air from the loud breathing turns into a froth or foam.
  • A dog who has the sour taste of his mouth might spit up and pant, forming a foam that stays around the mouth.
  • The nausea can cause dogs to spit and pant, which creates foam that surrounds his mouth. Based on the reason for nausea, it could be essential for your dog’s health to be examined by an veterinary specialist.
  • Anxiety or stress could be a reason for your dog to scream at the mouth. Drooling is often triggered by a reaction to stress or anxiety. The drool that occurs, in conjunction with the fast breathing of an anxious dog, could create foam in his mouth.
  • When your pet has taken any poison it is possible that he will foam at the mouth. If you suspect that your dog has ingested poison the dog, you must bring your pet to the vet immediately to avoid permanent damage or even death.
  • A dog that is having difficulties swallowing can also be foaming in the mouth. When your pet is having difficulty swallowing, it could be experiencing breathing problems and should visit a vet immediately to find out the reason for the issue.
  • Oral health issues can cause dogs to over-salivate and sweat because of stress. Abcesses, injuries and tumors could trigger this type of behavior and require vet medical attention.
  • The seizures can cause dogs to scream at the mouth. The seizures can cause dogs to salivate and quickly pant, creating foam at the mouth. Based on the severity of the seizure’s activity unpredictable or wild behavior can accompany the mouth foaming. This type of behaviour may occur briefly if the bubbling is due to seizures.
  • The disease can also trigger foaming in the mouth and an unpredictable behavior. Instead of these behaviors lasting for just a few minutes it is possible for the dog to behave in a erratic manner and then foam at the mouth for an extended period of time. The foaming is also caused by excessive drooling as well as fast breathing.

The reasons that cause a dog to swell up in the mouth vary in length and severity. If a dog is foaming in the mouth while playing will likely be back to normal after the exercise is over but a dog who displays mouth foaming without any known reason should be observed and possibly visited by a veterinarian to find out the cause of the rapid breathing and hyper-salivation. Although mouth foaming isn’t a serious issue in the majority of instances, if it’s followed by other symptoms seeking veterinary care is the next step to ensure the health of your dog.


General Tips for Preventing Dogs’ Foaming at the Mouth

If there isn’t a serious underlying issue that causes your dog to foam around the mouth. There are simple steps you can follow to stop or reduce the situation.

Keep Your Dog Hydrated

Make sure your dog has sufficient water prior to, during, and after intense physical activities. In the course of intense physical activities can cause dogs to lose a lot of fluids due to crying and panting. Refilling the fluid lost and ensuring that your pet has access to safe drinking water during play will help to keep foam from forming.

Regular Dental Care

They require regular grooming because they are susceptible to dental issues like dental decay as well as infections. These issues often require prescription medicines like antibiotics and surgical removal of infected teeth, as well as damaged or chipped teeth and polishing of the tooth.
At at home, you can do your part by brushing your dog’s mouth to reduce inflammation and prevent plaque creation. Make sure to use a high quality dog toothpaste. You can also consider giving it dental chews or treats to boost overall dental health.

Quality Food

Dental health issues like gingivitis can be result of inadequate diet. Inflammation that results from this can cause your pet to sweat when he licks his mouth. Therefore, feed your dog with nutritious meals that are high of essential vitamins, be it homemade or commercially prepared.

Keep Toxic Items Away

Similar to what we do with small children harmful chemicals, cleaning products such as plants, as well as other products that could be harmful should be kept clear of dogs to avoid poisoning taking in these chemicals. Also, ensure whether your home is free of harmful plants, toads, as well as Frogs before leaving your dog to roam around unsupervised.



The sudden appearance of foam in the mouth could be a cause of concern for novice pet owners as well as people who may not have had this happen to their pets. Fortunately, it’s not cause for concern because it’s usually caused by a quick resolution of a problem.
As we’ve discussed many of these issues are treatable at home by following a few simple steps and lifestyle modifications. In some instances these conditions, it may be necessary to get the assistance of a qualified professional to ensure that the dog is not suffering from a worse health.
However, there are a some potentially life-threatening illnesses that can cause dogs to gag at their mouths. This includes Rabies as well as seizures due to nerve issues. Although rare, they must be considered serious and your dog should receive the medical attention required immediately.
However, if your dog is foaming in the mouth, it’s likely not caused by a serious medical issue like Rabies especially when it’s had primary vaccines. The frothing should end when the cause or trigger is properly addressed This could include helping your puppy settle down, taking out the foreign object that is lodged in the throat or giving it the necessary attention at that time.
