Causes of dogs shaking and drooling:

1. Trauma or neurological disease. Some impacts or head neurological diseases can cause serious damage to the dog's central nervous system. Shaking and drooling are one of the typical symptoms. The owner needs to take the dog for treatment in time.

2. Poisoning. When a dog accidentally eats pesticides, rat poison, or chocolate, the dog will tremble and drool, accompanied by symptoms such as conjunctival cyanosis, difficulty breathing, vomiting, and diarrhea. The owner should take the dog to the pet hospital for emergency treatment immediately.

3. Infectious diseases. When a dog is infected with an infectious disease, such as canine distemper, he or she will tremble and drool, accompanied by persistent high fever, thick nose, and confusion. The owner can confirm the diagnosis by giving the dog a test strip test.

4. Vigorous exercise. After a dog consumes a lot of energy, it will dissipate heat through its tongue, panting constantly, and drooling a lot along its tongue. The owner can feed the dog a small amount of water to help dissipate heat.

5. Heatstroke. When a dog suffers heatstroke after being exposed to high temperatures, it will suffer from severe breathing and salivation that are more serious than during strenuous exercise. The owner needs to cool down the dog in time.
