Carrie Underwood and her husband Mike Fisher's family has grown by one. The country singer and her hockey player husband recently shared a photo of the new addition to their brood, and he is adorable.

On Fisher's Instagram account, the Nashville Predators player posted a photo of an adorable puppy they recently adopted. According to his caption, Underwood and Fisher's 3-year-old son, Isaiah, was the one who gave him his name, which is Zero. The puppy joins the couple's two other dogs, Penny and Ace.

"Meet the newest member of our family! Isaiah affectionately named him Zero. I guess it fits because it’s the chance of surviving if you try to break into our home #GSD," Fisher wrote.

The couple will soon be welcoming yet another addition to their brood as Underwood is currently pregnant with their second child. The singer previously revealed that they are expecting a bundle of joy in August, which is apparently the reason why her "Cry Pretty" tour will be kicking off in May.

"You might be wondering or asking, 'Carrie, why is your tour starting in May?' Well…yay!" she wrote in her pregnancy announcement. "Mike and Isaiah and I are absolutely over the moon and excited to be adding another little fish to our pond."

Over the past two years, Underwood has suffered three miscarriages. She previously opened up about this during a September interview with "CBS Sunday Morning." During the chat, Underwood said she had been looking forward to writing new music and having another child in 2017, but it "didn't work out."

Meanwhile, Underwood has been making sure to keep her fans updated on her pregnancy journey through Instagram. Earlier this year, she shared a sweet photo of her son laying his head on her exposed baby bump. In her caption, she revealed that she was wearing her husband's shirt and preparing to watch a movie with her "boys."
