Mandy Moore's family adopted a dog in January

The Dr. Death star can't stop expanding her family! At the start of the year, she revealed that her nanny had found a stray dog a few miles from the family home, and well, one thing led to another, and they ended up keeping him.

"Welcome to the family, Marshmallow! This sweet boy was found wandering the streets for several days, many miles from here by our beloved nanny, Celina. He’s about 6-7 months, unchipped, not fixed (but scheduled for next week) and just the most unexpectedly wonderful addition to our gang. We weren’t looking for another dog but he was looking for us and the fact that he looks remarkably like our dear Joni made it too impossible to ignore," she shared, adding, "The cats are nonplussed and Jackson (our 14 year old shepherd mutt rescue) is also a little 🤷‍♀️ but Marshmallow is slowly winning them over. When we showed Gus a picture of him and asked what his name was, without hesitation he shouted 'Marshmallow!' With his arms in the air. Done and done. Can’t wait for all of the adventures, sir!! #adoptdontshop."

And that attitude right there is how we know Mandy and Taylor are amazing parents. This little girl is so lucky!
