On Monday, during a press conference, Yang became emotional as he explained to reporters why he couldn't keep Grizzly. "That still hurts," he said of giving away the dog during a press conference on Monday, a video of which was shared by the New York Post. Yang said he was initially "in denial" that the dog was the cause of his eldest son Christopher's severe allergies. "There was one night when Christopher had a respiratory attack..." he said, tearing up. "And that's when I knew we had to give our dog away." Grizzly now lives with close friends of the family in California "who pamper him probably more than me and Evelyn did," Yang said. Explaining why he chose to post about the dog even though he's no longer with their family, Yang said Grizzly is "still our pet in our hearts." "I didn't really think anything of it," he said. "Grizzly meant the world to me and the family." Replying to her husband's original National Pet Day tweet, Evelyn Yang wrote that Grizzly is "a happy beach dog now but he'll always be our dog even though he doesn't live with us!" "Whenever we visit, grizz always gives me a kiss first and then proceeds to hound Andrew non-stop to play," she added, sharing a photo of Grizzly soaking up the sun.
