Many dog owners come to treat their animals as if they are part of the family. Fast and Furious 6 actress Eva Mendes is one of those people; after purchasing a shock collar for her dog she tried it on herself first.

On The Late Show with Dave Letterman Wednesday night, Mendes said I've tried it on myself at all levels, I swear," she said on The Late Show With David Letterman. "I do not do it on my neck. I tested it on my arm. It's more than a tingle, it's way more than tingle. Oh, remember when we were kids and we had that jokey thing where you shake hands and ah that thing? It's like that, but intensified the higher you go with the levels."

The shock collar is for her Belgian Malinois named Hugo, which as proven to be a hyper dog, according to Examiner.com. On The Late Show she explained the need for this collar.

"I'd feel terrible if he hurt a little thing so I try to get in there and I use -- people always get mad at me for this -- but I use a shock collar on him, and I have the remote."

Mendes is set to star in Fast and Furious 6 alongside series stalwarts Vin Diesel, Paul Walker and Jordana Brewster. Dwyane "The Rock" Johnson appeared in Fast 5 as Luke Hobbs, a violent but effective special agent and will be returning in that role. Rapper Ludacris, who has appeared in Fast Five and 2 Fast 2 Furious, also returns at Tej Parker, the street-racing group's tech master.

Michelle Rodriguez returns to the series in this film, reprising her role as Letty, who was believed to be killed in the fourth installment, Fast and Furious. Jason Statham is also listed in the credits on IMDB.com. He is rumored to have a cameo in the film that sets him up as the primary antagonist of Fast 7.
