You can cross restaurants, supermarkets, and beauty salons off the list of places you may visit with your pooch. Health codes ban dogs from such establishments (unless you have a service dog). When it comes to other destinations, always check ahead, even if you're planning to visit a close friend. But before you ask, take an honest look at your pet's behavior. You may think her manners make her Westminster-worthy, but if she has accidents, barks, or nips, reconsider. When heading to a place that does welcome dogs, bring paper towels, plastic bags, and treats. For all-day excursions, pack a portable water bowl.
