UrbanHound calls itself “the city dog’s ultimate survival guide,” and the site is a great resource for dogs living in New York, Chicago and San Francisco. It’s also a great resource for dogs visiting those cities — in particular, the sections on Hound Play, Hound Health and Hound Services provide lots of useful information about dog parks, swimming holes and fun things to do; 24-hour emergency vets (in Chicago and S.F., not provided for NYC); and dog services like day care, walkers and groomers, and shops.
The default city, when you arrive at www.urbanhound.com, is New York. Click on “change city,” under the logo, to access Chicago and S.F. information.
