Give your Shibos dog a break with a change of scenery. Find out which cafes near you are pet-friendly, and take your dog out for lunch or dinner. Hitch up their harness and walk to the café which will give your dog a chance to wear off some of their energy, before stopping at the café for some yummy food. Some cafes even have a pet menu, but if none near you do, take your own three course meal for your canine companion. This activity will require good behavior from your dog, which is part of their training. Spread out their meal so that it takes a while and they will get to watch the pedestrians and their pooches walk on by. On the walk home, stop at a park and let them wear off some of their lunch before heading home to chill out.
This activity is a form of training and yet, it is a lot of fun for your dog. Having a child join in with your dog will help, but you can do it alone. The idea is to get your dog to run around, perhaps chasing a toy on a string (or a child), and when you say 'stop' the dog has to stop and drop. Then when you say 'go' they can start chasing again. Highly praise your Shibos when they get it right, and give them a treat. It may take your dog a while to get this one as they will still want to chase the toy (or child). But it will teach them to leave whatever they are doing to stop and drop. It is an ideal skill for them to learn for when they are out at the park and start to follow another dog. The secret is to give high praise for this action and a treat, too - then they will be happy to do as you wish.
Dogs, for some reason, seem to love playing with balls. Include some ball games such as soccer in their day. Another game is to teach them to catch the ball. You will need a ball that they can get in their mouth but not too small that they can swallow in the excitement. Then, practice just a foot apart by throwing the ball to your dog. If they catch it, they get a treat and make a big deal of it. Really praise them up! Before long, your dog will be a superstar at catching the ball. Then you can chuck the ball further away, or to the side of your dog. Give them a good work out, but also give them a few breaks to catch their breath. You want the game to be fun, not a marathon. Be happy and your dog will be happy and contented, too.
