There are many reasons why dogs keep barking. For example, dogs will bark non-stop due to emotional stress in a strange environment. This is very likely to happen to puppies that have just been brought home. It is recommended that owners create a safe and comfortable environment for their puppies and try to leave them alone.
Secondly, consider how the dog is affected by the surrounding environment. For example, if there are other dogs around, the dog will be afraid or threatened. Keep calling. Finally, considering the cause of pain, dogs may also keep barking when they feel severe pain. If your dog keeps barking and shows symptoms of pain, it is recommended to take it to the pet hospital for further examination and treatment in time.
