Pratt, Montag 'get second Maltipoo puppy'

Spencer Pratt and Heidi Montag have reportedly added a second puppy to their family.

Pratt treated his wife and Hills co-star Montag to a Maltipoo called Dolly for her 23rd birthday earlier this month.

Speaking to People, the couple said: "We're getting Dolly's brother and naming him Inky The Ninja!"

Dolly, who is a few months old, was named after singer Dolly Parton. The new puppy, a black Maltipoo, will join the family shortly.

The new season of The Hills premieres on MTV tomorrow night.
