Cell phones that only make and receive calls are so 2008! With a satellite signal and Internet access, today’s smart phones put the world—both yours and your dog’s—in your pocket.
1. Keep track of your pup’s day-to-day doings using the DogiDuty  app; iPhone-toting dog walkers or sitters can manually file reports on her intake and output, then email them to you.
2. Pump up your walk. Map, record and share details of your canine-centered excursions at MapMyWalk.com  or with your very own Google Earth Tour . As walks get longer, the Sit or Squat  app, with its inventory of public bathrooms, comes in handy. Meanwhile, Eukanuba’s Off Leash  iPhone app shows you the way to the nearest dog park.
3. Keep them healthy. Sign up for alerts about pet product hazards at HealthyStuff.org  and pet food recalls at FoodSafety.gov . And be prepared for the unexpected—take along a Red Cross–trained assistant with the Pet First Aid  iPhone app. You can also use your smart phone to store and access your dog’s medical records and keep track of appointments; the Pet Phone  app puts that info at your fingertips.
4. Share a night out with your furry friend. With OpenTable.com , find restaurants that celebrate canine companions, then make your reservation.
5. Discover hidden treasures. Now that most of these phones are GPS-enabled, the once arcane (and obsession-forming) hobby of geocaching is within the reach of newbies. Get started at Geocaching.com .
8. Focus on housetraining. Have a new puppy? With iPottyTrain , set alarms to remind you to take the pup out for a break, and log hits (and misses)—all of which keeps this important activity at the forefront of your attention.
9. Entertain yourself. During those quiet moments while waiting for the vet to arrive in the exam room, test your dog knowledge with Dog Trivia  or play with the Obama’s Bo via The First Dog  (at the time of release, a portion of the download fee was donated to the HSUS).
10. Carry a spare. Admit it—sometimes you go out with your dog but without your clicker. With the Clicker  app, this training tool is always at hand (assuming you don’t also forget your iPhone).
