  • Karl Lagerfeld's Choupette

    Ahh, to be Choupette. First, she's clearly one adorable white fluff ball. But she also had the good fortune to become the beloved (and <a href="http://www.crittr.com/karl-lagerfelds-kitten-has-it-all" target="_hplink">amazingly spoiled</a>) pet of the iconic Chanel designer. Karl Lagerfeld admitted in a magazine interview this year that Choupette eats at the table with him and has two maids who record her every move so that he doesn't miss a thing about her day. <a href="https://twitter.com/KarlLagerfeld">Choupette</a>

  • Katherine Heigl's Beloved Pups

    Actress Katherine Heigl readily admitted to <em><a href="http://yourlife.usatoday.com/parenting-family/pets/story/2012-01-24/Katherine-Heigl-The-Mad-Dog-Lady/52756226/1" target="_hplink">USA Today</a></em> that she's a "mad dog lady." And she can prove it: She has seven pups at home. (Shown is her dog Oscar with her daughter, Adalaide.) The animal activist's <a href="http://jasonheiglfoundation.org/" target="_hplink">Jason Debus Heigl Foundation</a>, named for a brother who died as a child, aims to "eliminate the needless suffering inflicted on animals." <a href="http://instagram.com/p/QyhCZqNgBH/">Adalaide</a>

  • Miranda Lambert's Puppies

    The country crooner owns nine dogs, but that hasn't stopped her from helping more! This year, she rescued one puppy from a ditch, then managed to find homes for six <a href="http://www.vetstreet.com/dogs/german-shorthaired-pointer" target="_hplink">German Shorthaired Pointer</a> puppies she found outside an Oklahoma day care center. Once the last pup was adopted, she tweeted, "If you weren't able to get one of these sweet angels..please visit your local shelter! Don't forget..love a shelter pet!" <a href="https://www.facebook.com/notes/muttnation-foundation/muttnation-foundation-needs-your-help/438912656142211">MuttNation Foundation</a>

  • Taylor Swift's Meredith

    Another country girl, Taylor Swift, is (much) more of a cat person. This year, she has shared plenty of <a href="http://www.crittr.com/taylor-swifts-cat-watches-the-olympics" target="_hplink">photos</a> and <a href="http://www.crittr.com/taylor-swift-plays-fetch-with-her-cat" target="_hplink">videos</a> of the kitty she adores, Meredith -- and they've quickly gone viral. The <a href="http://www.vetstreet.com/cats/scottish-fold-highland-fold" target="_hplink">Scottish Fold</a> is named for Meredith Grey, the character played by Ellen Pompeo on <em>Grey's Anatomy</em>. And we imagine she's the inspiration for the <a href="http://www.eonline.com/news/361065/meow-taylor-swift-totally-has-a-thing-for-cat-fashion" target="_hplink">cat-themed fashions</a> Swift has showcased this year, too!

  • Sherri Shepherd's Ashley-Chloe

    Comedian and host of <em><a href="http://theview.abc.go.com/" target="_hplink">The View</a></em> Sherri Shepherd knew what she wanted when she searched online for a rescue dog: a black<a href="http://www.vetstreet.com/dogs/labrador-retriever" target="_hplink"> Lab</a>. "I specifically wanted a Lab because I had a Lab who passed away at 12," she told <em><a href="http://www.peoplepets.com/people/pets/article/0,,20655358,00.html" target="_hplink">People</a></em>. "And I wanted a black dog because there is something called Black Dog Syndrome. Black dogs are the last to be adopted [because] when you take a picture of them in their cages, they look menacing behind the bars." Now, 3-year-old Ashley -- who's going to be renamed Chloe but is currently known as "Ashley-Chloe" -- is happy at home in New York with Shepherd. <a href="https://twitter.com/SherriEShepherd/status/278242267012141057">Ashley-Chloe</a>

  • Mark Zuckerberg And Priscilla Chan's Beast

    Some dogs get to take part in their owners' nuptials, but how many get to <a href="http://www.thehollywoodgossip.com/2012/05/beast-zuckerberg-the-worlds-richest-and-possibly-cutest-dog/" target="_hplink">walk the bride down</a> the aisle for one of the year's most high-profile weddings? Beast, the shaggy <a href="http://www.vetstreet.com/dogs/puli" target="_hplink">Puli</a> with more than 1 million <a href="https://www.facebook.com/beast.the.dog" target="_hplink">Facebook fans</a>, played that role for Priscilla Chan when she married longtime love and Facebook CEO Mark Zuckerberg.

  • Martha Stewart's G.K.

    He may not have won Best in Show, but domestic diva Martha Stewart's <a href="http://www.vetstreet.com/dogs/chow-chow" target="_hplink">Chow Chow</a>, Genghis Khan, aka G.K., won <a href="http://www.peoplepets.com/people/pets/article/0,,20573258,00.html" target="_hplink">plenty of attention</a> while competing at this year's Westminster Dog Show. G.K. was Best of Breed but didn't advance to be a group winner. There's always next year, G.K.!

  • Jimmy Fallon's Gary

    The <em><a href="http://www.latenightwithjimmyfallon.com/" target="_hplink">Late Night</a></em> host's penchant for <a href="http://www.vetstreet.com/dogs/golden-retriever" target="_hplink">Golden Retrievers</a> was already clear -- he'd become known for having them on the show as "<a href="http://www.vetstreet.com/our-pet-experts/pet-scoop-jimmy-fallon-talks-super-bowl-with-puppy-predictor-phil-sees-his-shadow" target="_hplink">puppy predictors</a>," to weigh in on the outcomes of events including the Super Bowl and the Academy Awards. So, perhaps we could have predicted that he'd end up bringing home one of his own! By the time the presidential election came around, his Golden pup, <a href="http://www.wptv.com/dpp/news/local_news/water_cooler/jimmy-fallon-dog-gary-chooses-mitt-romney-as-election-2012-presidential-race-winner-video" target="_hplink">Gary</a>, was the one doing the predicting -- though, um, not correctly, as it turned out. <a href="http://instagram.com/p/P7S1-YPZ5H/">Gary</a>

  • Celebrity Pets That Had the Best 2012

    Andy Murray's Dogs

  • Britney Spears' Hannah

    The pop star and <em>X Factor</em> judge also brought a new puppy home this year -- and quickly introduced her to Twitter. Tiny <a href="https://twitter.com/hannahspears" target="_hplink">@HannahSpears</a> had nearly 25,000 followers in just a matter of weeks. From Hannah's tweets, there are a few hints that the mom of two boys may be doting on this little girl. "Anyone seen my leopard dress? I can't find it anywhere," Hannah asked this month.
