Marnie
If you've never heard of Marnie - where have you been? This 14-year-old Shih Tzu was found smelly and matted on the streets of Connecticut in mid-2012 and quickly moved to a shelter. Known for her long, droopy tongue and her distinctive head-tilt, Marnie is hands-down the most popular rescue dog on Instagram - she even released her own book last year and has been profiled in the New Yorker. A poster-girl for senior rescue dogs everywhere.
Menswear Dog
The most stylish dog on the internet, Menswear Dog (aka Bodhi) is a Shiba Inu with a penchant for Ted Baker, and looks better in a suit and sunglasses than most of us ever will. What began as a joke for Bodhi's owners soon become a viral sensation. In 2014, the Daily Mail reported Menswear Dog pulls in $15,000 every month through modelling gigs.
