In 2009, the bulldog pushed aside Labradors to become L.A.'s most popular breed. Adam Sandler, Angelina Jolie and Brad Pitt are owners, as is Victoria Beckham, whose Coco can be seen on Twitter shopping at Hermes.
2. Labrador retriever
Family-friendly Labs still are No. 1 nationally. Local breeder Teresa Bergquist of Susana Labradors, whose puppies have starred in Bridesmaids, explains their appeal: "They're intelligent and can count and memorize."
3. French bulldog
The French bulldog, exemplified by Modern Family's Stella, has jumped two spots since 2011. Bred during the late 1800s to be lap warmers, they're seen on the leashes of Reese Witherspoon and Hugh Jackman.
4. German shepherd
Employed worldwide as skilled guard dogs, German shepherds are strong, loyal and known as a one-man breed for their allegiance to their owners -- Ben Affleck, Nicole Richie and Jennifer Aniston, among them.
5. Golden retriever
The friendly golden retriever became a breakout breed after 1997's Air Bud. Up one slot from No. 6 in 2011, these old reliables, used in search-and-rescues and as guide dogs, no doubt signal stability to their industry owners.
6. Yorkshire terrier
The Yorkie might have been used as a rat catcher in 19th century England, but nowadays the breed is coveted by celebrities like Miranda Kerr. Highfliers take to their travel-friendly portability and entertaining personalities.
The poodle comes in three sizes -- standard, miniature and toy -- for owners who like options or are allergic (but don't mind frequent grooming). Blake Lively's toy, Penny, was a constant companion on the set of Gossip Girl.
L.A.'s most popular toy breed (Chihuahuas rank at No. 28), Poms demand a lot of attention, which owners like Gwen Stefani happily provide. Channing Tatum and wife Jenna often are photographed walking their Meeka on city trails.
9. Toy spaniel
The sweet disposition and trainability of Cavalier King Charles Spaniels makes them great therapy dogs. Julianne Hough has posted about her two dogs on Instagram: "Can't move! Babies are taking care of me."
10. Shih tzu
With its long double coat that requires daily brushing, the shih tzu -- the breed of Kerry Washington's canine Josie -- has been around for a thousand years. It was bred to be a house pet during China's Ming Dynasty.
