Sure, vampires and weredogs have never gotten along in Bon Temps, La., the fictional setting of HBO’s hit series True Blood, but when Stephen Moyer marries costar Anna Paquin, those of the furry kind will be well-represented in the wedding party.

“Splash, my alpha, will be the ringbearer,” Moyer said at the L.A. Dogworks and Good Dog Animal Rescue fund-raiser on Wednesday in Los Angeles. “My son [Billy, born in 2000] might be unhappy about that.”

But Splash, a 10-year-old border collie that Moyer calls “a grumpy little sod” and “lunatic who is getting old,” won’t have to worry about getting fitted for a tux quite yet. Moyer, 39, and Paquin, 27 – who spent nearly the entire event holding hands – haven’t set a date yet.

“We haven’t planned anything,” Moyer said. “People say, ‘You are engaged to be married,’ and I’m like, ‘Really? I thought we were just engaged.’ ”

At least there’s an engagement ring. Moyer’s friend Cathy Waterman, a California jewelry designer popular among celebrities, created Paquin’s ring, which includes what Moyer described as a dark-colored “rustic diamond.”

Last night at least, Moyer, who plays vampire Bill Compton, and Paquin, who plays Bill’s telepathic girlfriend Sookie Stackhouse, put his focus on fundraising.

“They don’t get paid for what they do, it’s all run on donations and lots of the vets that work for them still charge because there’s things to charge for,” Moyer says. “They’ve been paying out of their own money and it’s fortunes. People are coming, so hopefully, it’s working.”
