Your dog considers you part of his pack, and if you don't spend time with him he'll feel confused and lonely, and wonder why his pack is treating him this way. Make sure you play with your pet and take time to train him. Dogs and cats that are left alone too much or don't get enough exercise can become bored and lonely. They might tear up the house or chew up your favorite toy in frustration. Dogs need to run.
Cats can get a lot of exercise by playing with their toys or jumping on the furniture.
Make sure your pet gets enough exercise.
