Exercise your dog!
An exercised dog may rest more calmly at home and be less nervous when left alone. Exercise can improve dogs bone and joint health, heart, and lung function. Exercise makes show dogs look better and feel better to a judge's exploring hands. (Because a happy dog looks more gorgeous).
The best exercise channels the activity of both mind and body. Some people believe that dogs need a big garden so they can get plenty of exercise. The truth is that most dogs do not exercise when they are outdoors by themselves; they spend most of their time laying in the shadow and waiting for "their people" to play with them.
You do not need to take up marathon running in order to adequately exercise your dog.
Make your walks interesting. Let your dog carry a box, a basket, or a toy while walking. Let your dog jump or balance over a tree, hide his toys, hide yourself, and most important – let him play with other dogs! Open the leash when another dog approaches, to prevent “leash-aggression”. (Don’t worry, they will not kill each other). A dog that tries to "guard" against all strangers is neither happy nor likely to live out a full lifespan. Help your dog learn to enjoy other dogs and people.
Teach your dog to retrieve. A dog who retrieves is easy to exercise. But throw the toy rather far than high. Jumping high in the air to chase it and landing awkwardly may lead to serious knee injuries.
games to play
Tunnel exercise - Make a tunnel or maze with some old cardboard boxes or chairs and encourage your dog to explore and go through it.
Concentration exercise – Hide some treats inside an old wash-glove or in a rolled up towel, this is fun for your dog!
Brain exercise – Turnover a bowl and hide the treats under it. Doggie must use his creativity to turn the bowl and get all treats. That is exciting exercise!
Have fun together!
