Dogs dig on the bed primarily due to instincts inherited from their wild ancestors. This behavior helps them create a comfortable resting spot by fluffing and arranging bedding, mimicking how they would dig to make a shelter in nature to regulate temperature and remove obstacles. Additionally, dogs dig to mark their territory with the scent glands in their paws, to nest especially if pregnant, and sometimes due to anxiety or playfulness. It can also be a way to seek comfort or attention. Key reasons include:
- Instinctual nesting and comfort preparation before settling down
- Temperature regulation through digging for warmth or coolness
- Marking territory by leaving scent from paw glands
- Releasing energy or anxiety through playful or repetitive digging
- Natural hunting or investigating behavior carried over from ancestors
This behavior is considered natural and normal, though excessive digging might warrant vet advice for anxiety or physical ailments.
