“Adolescents need stimulation as well as structure, and lots of it. If our teenagers are involved in after-school activities…they’re far less likely to explore the seedier side of life. The same is true with dogs. Any kind of constructive activity, whether it be physical or mental, will have numerous positive effects on your adolescent dog.”
Trish King writes in Parenting Your Dog.
This applies to mature dogs as well. Keep them active with interesting mental and physical activities so you can have a happier home life with your canine friend.
Your dog will have a healthier and longer life.
