The couple shared a photo of the trio on Instagram, and Sophia wrote:"Two main characters and one who takes care of both of them 🥰 Say hi to Mishka ❤️🐶"The newest family member is already in travel mode with Zverev and reportedly even has an official pass to attend matches. Mishka was there when Zverev was playing in Vienna. Thomalla even shared a photo of Mishka enjoying Zverev's match on live TV.Two years ago, Zverev celebrated Sophia's birthday by calling her multitalented, and one of those skills happened to be "dog-sitter."“Happy birthday to the multitalented physio, panda mom and dog sitter,” he said. “Lack of career options was never a problem but I thought people should know the most important ones."This isn't the first time that Zverev has had a dog. He has previously adopted a teacup poodle named Løvik since about 2018, and in 2019, he adopted a terrier mix named Pop after visiting a Miami shelter.
