Puppies are sentient animals. They express their joy, sadness, anger and other emotions by barking. If the dog hears the owner's voice or smells the owner coming home, it will bark happily to welcome the owner. On the contrary, if the puppy is in danger or afraid, it will bark to express its tension and anxiety.

In addition to emotions, sometimes puppies also express their needs and demands by barking. For example, they may need their master's food or water, or they want to attract their master's attention, or they need to go out for a walk. They all send messages to their master through barking.

The puppy barks to protect the territory.

The ancestors of puppies are wolves, and they are born with the instinct to protect their territory. When the puppy thinks there is a threat around it, it will bark to warn its owner and express its willingness to defend its territory. This instinct is also one of the important conditions for human beings to train dogs to protect their homes.

In the wild, wild dogs will also bark to give coordination and instructions to their companions. Through different calls, they can convey different information and intentions to ensure their survival and reproduction.

The puppy barks to communicate with its owner.

Puppies' language ability is relatively limited, but they will try their best to communicate with their owners through different barks. For example, when a puppy wants to play, it will attract its owner's attention with a low and clear cry. When a puppy wants to hug or ask for food, it will make a loud cry to express its dissatisfaction or expectation.

At the same time, the owner can also understand the intentions of the puppies by listening to their barks. If the puppy barks frequently for a long time, it may mean that it needs the owner's attention or feels uneasy. The owner can calm his mood and relieve his nervousness by interacting with the puppy.

The puppy barks to get used to it.

Sometimes puppies bark, but there is no specific reason. This may be because the owner did not train the puppy in time when he was a child. In the process of growing up, puppies need clear behavior norms and training in order to gradually develop good habits. If there is no standard training, puppies may have some bad behavior habits, such as barking and attacking.

Therefore, for the training of puppies and the formation of good habits, owners need patient education and guidance to gradually adapt them to human life and behavior norms.
