The beach is the perfect place for dogs. Wide open spaces, water for swimming, sand for drying off, and plenty of games and sports to play. Just be aware of how deep your dog is going in the waves, which you can do by easing him into the ocean with a leash. Petco carries great dog life vests for beginner swimmers. If your dog prefers to stay on dry land, then get him to play fetch with a ball or Frisbee. With all the swimming and running around, your dog is bound to get thirsty, so be sure to keep him hydrated throughout your day in the sun.
