San Diego, Calif.
With its year-round warm climate and 70 miles (112 kilometers) of white-sand beaches, San Diego is an ideal spot to get outdoors with your pet. Many of the beaches allow animals, and at least two will even let your dog roam without a leash -- perfect if you want to play a game of Frisbee. Just a few yards away from the appropriately named Dog Beach is one of the area's pet-friendliest hotels -- Ocean Villa Inn. Many of the rooms have private patios that open out to a communal yard across from the beach.
If you love to shop but hate to leave your pets at home, the Otay Ranch Town Shopping Center has the solution. Although animals aren't allowed in the stores, the shopping center has a doggy park and offers pet-sitting for a minimal charge. Several area stores do cater to pets, however, including Paw Pleasers, a bakery specializing in doggie birthday cakes and ice cream. If your dog is in the mood for something more savory, there's Terra, a restaurant in the Hillcrest Community. The menu features puppy pizzas, gourmet sausages and peanut butter rawhide.
San Diego even has canine-themed events. Visit in the summer, and you can take in a Padres game with your best friend during the annual Dog Days of Summer event.
