The 30-year-old singer, whose own dog Maltipoo died in 2009 after being snatched by a coyote, said that it is like having a new dog all over again.
'His name's Bentley, he's an Airedale terrier [and] he's adorable,' she told People magazine. 'He's the best dog. I love him to death.
'At first he would growl at me, and now he comes and snuggles up to me,' she said. 'It's like I have a brand new dog.'
And she added that they will be looking to extend their doggy family even more.
'Eventually, I think we want to get something,' she said. 'Whoever Bentley will get along with.'
