Philadelphia Fish & Co. as well as the Continental are many Old City establishments with pet-friendly environments. In University City the appropriately named White Dog Cafe, encourages diners to eat al fresco with their canine companions. In Manayunk, Le Bus and Derek's also provide complimentary water bowls while dining outside.
If grooming and pampering is what you're looking for, stop at Bonejour in Old City, which features canine couture as well as beds, leashes etc. Chic Petique , located just off of South Street, is fully stocked with the everday items as well as treats shaped like human food and objects. For a place to play, try The Center City Dog Park so your mutt can mix and mingle with the rest of the canine population.
