The AKC said a review of 2007 registration statistics found Bear, Blue, Max, Duke and Buddy were the most popular names for male dogs while Lady, Belle, Princess, May and Rose were the most popular for female dogs.

"Traditionally names based on a puppy's physical appearance or personality, such as 'Spot' or 'Sassy,' have been popular with dog owners,'" said AKC spokeswoman Lisa Peterson. "Today we are seeing human names, such as 'Jack' and 'Molly,' and names that reflect a pet's stature in the home, such as 'King' and 'Princess,' gain in popularity as more people consider their dog a valued member of the family."
