Dogs are considered highly social animals. While they may have different personalities and comfort levels when alone, a lack of socialization (whether with humans or other dogs) can lead to feelings of loneliness.

Factors that contribute to loneliness in dogs can include:
– Spending time alone for an extended period (e.g., while you’re at work, at school, or traveling)
– A lack of mental stimulation
– Major life changes
– Changes in their routine, especially because of a change in your schedule
– A loss of a companion, as dogs can experience grief
