Previous research shows that our romantic preferences don’t usually match up with the partners we choose. A new study says there is a similar pattern when it comes to adopting a dog.

Researchers from Indiana University categorized dogs at a local animal shelter based on 13 traits including age, sex, size, color, breed, playfulness, and friendliness. Then, the team asked visitors to list their trait preferences, which were later compared to the dog they ultimately adopted. 

Surprisingly, their new companion often varied greatly from their original list of preferences. 

Researchers say these findings mirror a similar pattern in dating: the traits we actually value are different from those we originally thought were most important.
