Jake Gyllenhaal and James Gandolfini riding the Puggle trend

They're not new--they've been around for about five years--but Puggles are taking the world (and Hollywood) by storm. Their popularity continues to rise, and the American Hybrid Canine Association notes that puggles are the most popular type of dog among the 500 litters a month the group registers. The dogs were selling for about $450 in April, and now it's common to see them listed for more than $1,000.

The breed is also popular among celebs, with Jake Gyllenhaal and James Gandolfini among the stars who've adopted the dog. Jake, in particular, has been heard raving about his new pooch to friends and family.
