I'm not familiar with the basic research, but the article itself is one big non sequitur. It starts with the subtitle "Dogs improve office productivity" and proceeds to establish that:
1. "those who had had a dog ranked their team-mates more highly on measures of trust, team cohesion and intimacy"
2. in the Prisoner's Dilemma game, dogs "made volunteers 30% less likely to snitch"
At best, this tangentially indicates that the presence of one dog in the office has the potential to improve team cohesion. There's a big step from that to productivity.
