“Oh my God, I tried to bribe the trainer to sell me the dog,” Wahlberg reveals to PEOPLE. “I offered her whatever she would want. But, of course, that bond is not something that you can separate. I just fell in love with him.”

Thefather of fourshares that his children also “wanted me to bring him home” after growing close with his adorable costar. “But I completely understood … I took a shot,” Wahlberg adds.

The Family Planstar recalls his experience working with canine Ukai being “amazing,” which led to the actor having plenty of happy memories from the set.

“You know, we had many amazing moments,” Wahlberg says. “[My favorite moment] I would have to say anytime when the real race started for me, after the race was over and they crossed the finish line.”

He continues, “But when the race to save Arthur started, that for me was like the real movie. That was the race. So to be able to do any scenes with Ukai, as Arthur, on an emotional level and to see how powerful his performance was was awesome.”
