Boredom and excess energy are two common reasons for behavior problems in dogs. This makes sense because they’re meant to lead active lives. Wild dogs spend about 80% of their waking hours hunting and scavenging for food. Domestic dogs have been helping and working alongside us for thousands of years, and most are bred for a specific purpose, such as hunting, farming or protection. For example, retrievers and pointers were bred to locate and fetch game and water birds. Scent hounds, like coonhounds and beagles, were bred to find rabbits, foxes and other small prey. Dogs like German shepherds, collies, cattle dogs and sheepdogs were bred to herd livestock.
