Being a dog-lover is not a choice, it is in your DNA.
This finding from a team of researchers in Sweden and England sheds some light on how man's best friend came to be and found being a dog owner is may be genetic.
A study of twins found that getting a dog is influenced by an individual's genes and may even be inherited.
It is impossible to say which genes are involved from the study but identical twins agreed far more than non-identical pairs on whether they would have a pet pooch.
Previous research found if we had a pet as a child we are more likely to like animals and own a pet in adulthood.
But it was unclear if genetic differences between families contribute to this association.
Lead author Professor Tove Fall, of Uppsala University, said: 'We were surprised to see that a person's genetic make-up appears to be a significant influence in whether they own a dog.
