Not only will the actor's hit series return for a fifth season on Sept. 25, but he's also proud papa to a new Chihuahua.
"We just adopted a little dog," Dane told PEOPLE at Friday's Sixth Annual Tom Arnold Roast, to benefit the Exceptional Children's Foundation. His wife, actress Rebecca Gayheart, was his date at the event.
The dog's name is Nellie, "like 'Whoa, Nellie,'" Dane, 35, explained. "We adopted it on the street from this adoption agency. She was thrown out of a car, so we took her."
"She's a rescue," Gayheart added.
Dane and Gayheart, 37, will celebrate their four-year wedding anniversary on Oct. 29, but don't have anything elaborate planned and will just go with the flow.
"As long as we're together, it's fine," Gayheart said. "The two of us, dinner."
One thing is for certain: the dog doesn't count as Dane's anniversary gift to his wife.
"It's not the anniversary present," Dane laughed. "What if the dog were the anniversary gift, I think it would be the last anniversary we have together! 'I brought you a Chihuahua...'"
The duo said they had a "great summer," traveling and visiting family. As for plot spoilers for Grey's fifth season, Dr. McSteamy is mum, only saying that viewers should expect more of what made the Emmy-winning series so popular.
"More of the same, and I think that's done well for us in the past," Dane says. "I think we're going to stick to that formula."
