There are many reasons why a toy might be important to you and your dog. For example, a toy as simple as a tennis ball may be perfect for a walk in the park to give a high energy dog an increased work out. A water toy may be perfect for a little excitement in the water.

Some dogs continue their fascination with chewing into their adulthood. Dogs may also turn to chewing to relieve boredom, frustration, and even stress, especially if a dog is left alone for a long period of time or his or her alone time is not consistent.
