Small dogs are awesome. Most of the time they are easier to care for and groomers charge less to cut their nails too. However, even small dogs need exercise. Your high energy small dog will inevitably get into trouble if their physical exercise needs are not met. They will become bored and will use their pent-up energy to chew holes in your favorite shoes or dig escape routes under your fence in the backyard. Yes, even small dogs need to be prevented from accidentally leaving your yard and getting hurt.
