There is no specific time for dogs to bark before an earthquake. It may be an hour or half an hour before an earthquake, or they may not bark at all. Dogs have a strong sense of perception, but whether they bark before an earthquake depends on the dog's IQ, acuity, and magnitude. If the magnitude of the earthquake is relatively small or the dog itself is not very smart, there may be no barking. .

Why do dogs bark before earthquakes?

The average Hertz value for a normal adult is between 20-20,000 Hz, while the average Hertz value for an adult dog is between 15-65,000 Hz. So dogs seem to be able to hear a wider range of sounds than humans, such as earthquakes, and can even hear ultrasonic and infrasound that humans can't hear.

Because dogs have super hearing and perception, they can sense an earthquake 30-60 minutes before it happens, and then they will keep barking to remind their owners. And at this time, in addition to barking, he will also show fear, running around, anxiety, etc.

Some sounds in life can make dogs uncomfortable, causing them to jump, fidget, or bark. Thunder, vacuum cleaners, fireworks, and firecrackers can make dogs more anxious and frightened. Therefore, when raising dogs, it is best for owners to provide their dogs with a quiet living space to avoid stress reactions.
