Dogs are a lot like children. If you don’t give them something fun to do, they will make their own fun—and often not in ways you approve of.
Give your dog plenty of physical and mental exercise, and you get a happier, healthier, better-behaved dog. Well-exercised dogs bark less, chew less, sleep more, and rest easier if left home alone. They are also much less likely to rummage through the rubbish or attack the couch cushions.
