Dog Behavior

Dogs value the companionship of the others in their "pack" and are sometimes distressed if they are separated from it. Typical reactions when a dog is separated from the pack are barking, howling, digging, and chewing. These activities may distress humans when they need to leave dogs alone for a period of time. However, this behavior, called separation anxiety, can be overcome with training, or at least decreased to the point where it becomes manageable. If young puppies are habituated to periods alone from an early age, this can normally be prevented entirely

From a young age, dogs engage in play with one another. Dog play is made up primarily of mock fights. It is believed that this behavior, which is most common in puppies, is training for important behaviors later in life. Research on puppy play has shown that puppies do not engage equally in both dominant and submissive roles in fights; rather, puppies will tend to start play fights with weaker puppies they believe they can dominate.Additionally, puppies will intervene in play engaged by other pairs. In these situations, the puppies overwhelmingly aid the dominant dog. Puppies do not show reciprocity in interventions, suggesting that they prefer to be dominant in a fight, and are being opportunistic in the short-term. In the long-term, intervention may aid the puppies in learning coordination.

Different Behaviors of Dogs

Aggression
Aggression in dogs is always for a reason. It is at times to show domination. However most of the times it is fear motivated. Protective, territorial, and possessive aggressions are also visible in dogs to a great extent.

Barking
Barking has several reasons. Most of the time, it is due to attention caused due to a threat. However, a dog also barks out of boredom. If he is a puppy and he does not have any outlet of energy, he is then also likely to bark much. He may also bark due to separation anxiety or some phobia.

Digging
Digging is the favorite pass time of dog, when he will find nothing to do he will start digging. He may also do it for seeking comfort or protection or seeking attention or wishes to escape.
