I don't doubt that pets have a positive effect. But some dog running around isn't the same as a pet. It might be beneficial for the dog's owner, but not for me (and presumably not for other people either). It's not my pet, it's somebody elses pet. Of course it seems possible to hire only dog lovers, who would all benefit from improved mood in the dog office. I just hope that not every company adopts the rule, because some scientist claims it will universally increase mood. A dog approaching in the street is very stressful, especially if you are in company of a small kid.
