WATCH: Zverev adopts two-month-old puppy in Miami

Defending Miami Open finalist Alexander Zverev famously travels the world with his dog Lovik, but his family about to get one puppy bigger, as he just adopted a terrier mix from the Humane Society of Greater Miami.

"I saw him, he crawled up to me and he never left me," Zverev told Tennis Channel's Prakash Amritraj. "He's still on my arm, he's very calm, he doesn't want to leave me and I'm taking him home."

It turns out, however, that he's not able to take the puppy home just yet—who he's thinking of naming Vasya. Zverev says he's not allowed to take the dog out of the country until it's six months old, so he hopes to leave him with family friends in Saddlebrook for the next four months.

Zverev wasn't the only one to make the trip to the Adoption Center. As part of Miami Open Unites, several players volunteered to help groom the dogs, which is supposed to help improve the odds of adoption—2018 Miami Open finalist Jelena Ostapenko had a particularly good time.

Ostapenko is set to play Indian Wells quarterfinalist Marketa Vondrousova in the second round, and Zverev, seeded second, will take on the winner of Sam Querrey and David Ferrer.
