As pet owners who have raised dogs, I don’t know if they have noticed that dogs sometimes do not bark but only make humming sounds, especially puppies. So what is the cause of this? Today’s article may be able to help bloggers clear up their doubts, so just read it if you’re interested.

1. The vocal cords are not yet fully developed.

If the puppy is just born within three months, and there are no other abnormalities, it is normal if it cannot bark and can only hum, because the puppy is still relatively small and its throat is not fully developed, so it cannot bark. When the puppy grows up, it will naturally bark.

2. Lack of security

Some puppies feel nervous and scared because they are not accustomed to the new environment and new owners, and they feel insecure, so they keep humming, trying to relieve their own stress in this way. If this is the case, the owner needs to comfort the puppy more so that it can become familiar with the new environment as soon as possible.

3. Sick

If the puppy used to bark, but suddenly stops barking, it may be sick, such as a cold, parasite infection, etc. Because the body feels uncomfortable, it does not bark, and symptoms such as listlessness, loss of appetite, and fever may also occur. If this is the case, the owner needs to take the puppy to the pet hospital as soon as possible to investigate the cause of the disease and then treat it symptomatically.
