A lot of saliva in a dog's traffic may be caused by motion sickness, poisoning, and neurological diseases. First of all, once a dog is motion sick, it will vomit, drool, shortness of breath, etc. Secondly, if a dog accidentally eats foods that people eat and causes poisoning, it will also cause a lot of saliva, and it will also be accompanied by symptoms such as convulsions and foaming on the mouth. In addition, if the dog suffers from epilepsy or infected with diseases such as canine distemper virus, it may cause a lot of drooling when these diseases occur. Therefore, if the owner finds that the dog's symptoms are serious, he must seek medical treatment in time.

1. Motion sickness

Like humans, dogs will also experience vomiting, drooling, shortness of breathing when they are motion sick. This is caused by discomfort in the exercise and balance disorder, which leads to the dog's feeling very uncomfortable and anxious. In this case, the owner should take some measures to relieve the dog's symptoms, such as driving the car slower, allowing the dog to adapt slowly and then increase the speed of the car. The windows can be opened and ventilated to allow the dog to breathe fresh air, which can relieve the dog's discomfort in motion sickness. At the same time, the owner needs to prepare tissues for the dog to help the dog wipe his saliva. If the dog is very uncomfortable, it is recommended to park the car and let the dog rest for a while.

2. Poisoning

If a dog accidentally eats food in the car and causes poisoning, it may cause poisoning symptoms such as drooling, convulsions, foaming, etc. For example, foods such as chocolate, onions, raisins, etc. are very dangerous for dogs. Therefore, the owner can check whether the dog has eaten certain foods that can cause poisoning.

At the same time, it is also necessary to pay attention to not leaving human food or other dangerous items in the car at normal times, and keep the environment inside the car clean and safe.

3. Suffering from neurological diseases

When dogs suffer from certain neurological diseases, such as epilepsy or infection with canine distemper virus, they will also experience a lot of drooling. This is because these diseases will affect the dog's nervous system, leading to an increase in oral secretions, and even serious symptoms such as convulsions and coma. In this case, the owner needs to take the dog to the pet hospital for professional treatment as soon as possible to relieve the symptoms and prevent the condition from worsening further. In addition, it is recommended that the owner take the dog for a physical examination regularly to detect and treat underlying diseases in a timely manner, which can effectively reduce the risk of similar symptoms of the dog.
