Watch Alexis Bellino Get Brutally Attacked By Dog While Her Mother Stands Idly By (Exclusive)

Alexis Bellino and her mother agreed to do "Marriage Boot Camp: Family Edition" to strengthen their communication and build a better relationship, but when the "Real Housewives of Orange County" alum got brutally attacked by a dog during a group exercise called "The Sacrificial Choice," Penelope barely even flinched.

In TooFab's exclusive sneak peek of Friday's new episode, Alexis slipped into a completely padded bodysuit, strapped on a helmet and got ready to run away from a well-trained Belgian Malinois that was ordered to chase and attack her.

Though the dog stopped at its trainer's command and Alexis wasn't injured physically, she was hurt emotionally when she realized her mom stood idly by while Alexis was being thrown to the ground and tossed around.

"My mom just froze on the sideline and didn't show concern or say, 'Oh my gosh, my daughter can't do this' or 'Are you sure this is safe?' or do anything like that," said the reality star in a later confessional. "I don't like it, and I don't understand it."

Throughout the season, Drs. Ish and V have accused Penelope of not being emotionally in tune with her daughter's needs or fears, and several Boot Campers agree.

"Part of the problem with [Penelope] and Lexi is that she doesn't show enough affection or emotion," noted Aaron Carter's mom, Jane, following the exercise. "I think that's who she is. It's just so ingrained in her."

As Bellino revealed to TooFab last month, she declined WEtv's offer to participate in "Marriage Boot Camp" with her then-husband, Jim Bellino, three times. The fourth time producers approached her, Alexis said she was given the option to bring along another family member.

Bellino said she initially chose her mom because she felt Penelope was smoking too much weed and Penelope felt Alexis started dating again too soon after her divorce, but the reality star soon came to learn that she holds resentment against her mom for cheating on her dad and breaking up the family, which she feels forced her to grow up too quickly.

"With all the help that 'Marriage Boot Camp' gives you, our real No. 1 bottom issue is I was being her parent because I was put in that role at 12, and we had communication issues," Bellino told us. "Those doctors know what they're doing, and I'm so thankful for the opportunity."

"Marriage Boot Camp: Family Edition" airs Fridays at 10 p.m. on WEtv.
