As children, we were endlessly fascinated by blowing bubbles, some of us still are. The great news is that your dog will be fascinated too. Buy some bubbles and blow them, for old times sake. The only difference is that your dog is going to see a shimmery ball that is begging to be caught. It should be fun for the both of you!
The next time you're at the pet store, look out for something to launch a ball. These toys come in all shapes and sizes, but their basic purpose is to launch your dog's favorite ball a few meters into the air. Your dog will then chase the ball. It is a basic principle, but one of the most fun ways to spend time with your dog.
