If you and your friends are thinking of a volleyball game in the sand, invite your pup to run back and forth with you as you play the game. They may even learn how to volley the ball!
Use sand dunes and other obstacles to create a natural agility course. Encourage your pup to run around and jump over these natural obstacles.
Some beaches are home to a host of beautiful birds and other wildlife. Be careful not to let your pup roam free and chase the birds, however.
