Do Dogs Remember Their Previous Owners?

Dogs do form strong bonds with their owners, and there is evidence that they can remember them even after a long time apart. In one study, dogs were reunited with their owners after six months of separation and showed high levels of excitement and affection, indicating that they remembered their previous owners. Another study found that dogs were more likely to approach and play with a familiar person (such as their previous owner) than with a stranger, suggesting that they had some memory of their previous owners.
