The Jersey Shore star (real name Paul DelVecchio) has partnered with the American Society for the Prevention of Cruelty to Animals (ASPCA) to help pets receive the care and supplies they need in its aftermath, a cause also close to Denise Richards's heart.
"Animals need a voice; they can't speak for themselves," DelVecchio tells PEOPLE. "It was especially important with me to team up with the ASPCA because not only in the wake of Hurricane Sandy, but in general their efforts change so many lives and save so many animals."
Jersey Shore's resident nice guy has had a soft spot for animals since growing up with a German shepherd named Dozer, and though his current schedule keeps him too busy to look after a pet, he looks forward to one day bringing an animal companion home.
"I love that animals are so loyal," he says. "They are always there for you no matter what."
As part of DelVecchio's campaign, the MTV star filmed a public service announcement that saw him share screen time with an adorable brown and white pup.
"Filming with Ruby was the best," he says of his costar, a Cavalier King Charles Spaniel who actually belongs to his publicist. "A few times in the middle of filming, Ruby would jump down or yawn. It was hysterical, she made the blooper reel definitely."
Last month, Jersey Shore costar Mike "The Situation" Sorrentino also lent his face – and abs! – to an animal advocacy cause, appearing shirtless in a new PETA campaign that urges spaying and neutering.
