Why does the dog keep barking all of a sudden?

A dog barking suddenly may be due to noise around it, the dog has a need, or the dog wants to attract the owner's attention. Dogs are very vigilant, so when there are abnormal noises around them, the dog will bark to remind the owner. Generally, the dog will stop barking after the noise stops.

When a dog has needs, such as being hungry, thirsty, etc., or when it wants its owner to play with it, it will bark to attract the owner's attention.

When a dog feels uncomfortable, it will tell you in many ways, and barking is one of them. When a dog makes a low, listless bark, the owner should pay attention to the dog. Are you feeling uncomfortable?
