Studies have shown that people and their pet dogs often develop similar looks over time, with participants accurately matching owners with their dogs in experiments.
Facial expressions and simple features like hair and body shape play a significant role in the resemblance between dogs and their owners.
Some scientists believe that owners often choose pets that reflect their personality and physique, leading to a perceived resemblance over time.
Other studies suggest that pets can "grow" to resemble their owners over time, although this theory is still up for debate.
