The dog owners who observe their pet’s behavior changes during their absence from home find that their dogs react differently when their owners leave. Although dogs do not feel emotions in the same way as humans do, experts on animal behavior and veterinarians recognize that dogs show distinct emotional reactions when their owners leave them. The presence of attachment signals begins from minimal distances and reaches its maximum point through severe attachment signals. Dog owners who understand their pets emotional state can develop proper routines which will help their pets feel secure and experience comfort.
Dog May Feel Temporary Loneliness

Dogs have developed into a breed which prefers to live in groups due to their social nature. When their primary companion leaves, some dogs may experience a brief sense of social absence until they settle into rest.
Curiosity About Where You Went

After their owner leaves, many dogs stay vigilant while they listen for sounds which match their owner’s footsteps or door movements. This behavior usually displays curiosity which causes no distress to the animal.
Mild Boredom

Some dogs experience boredom when they receive no active engagement. Boredom leads to various activities which include window watching, toy chewing, and pacing around.
Anticipation of Your Return

Dogs develop an understanding of their human’s daily movements through their daily activities. Some dogs become more alert when they expect their human to return while they move to sit close to doorways.
Relaxation After Routine Departure

Dogs need to establish secure surroundings before they will lie down and begin to sleep. Research using pet cameras shows that dogs frequently rest for much of the time owners are away.
Attachment-Based Waiting

Dogs wait at doorways because they want to be close to their owner who has left behind his scent. Through this behavior, dogs exhibit intense attachment and comfortable familiarity with their environment.
Excitement Build-Up

You receive a warm welcome from your dog because he cannot hold back his excitement about your return. Dogs show this behavior through tail wagging which they combine with jumping and delivering toys to their owners.
Sensitivity to Changes in Routine

Some dogs will remain alert and restless until they become accustomed to new departure times which have been changed.
Comfort in Familiar Scents

Dogs experience greater security during their time alone when they have access to bedding and blankets and clothing items which carry a familiar scent.
