If you want TONS of bubbles, buy Gazillion Bubbles. I don't know how they do it, but you get tons more bubbles with their solution. My Papillon loves to jump and chase and bite bubbles, so we go through about four 2 liter bottles every summer. It's one of his favorite things to do. And these bubbles are hard to find locally, so I get them through Amazon. They also last quite a while when they touch the ground to, and he likes biting them on the ground as well. I blow bubbles for him year round, and this spring we even had some land on the ground, freeze, and were there the next morning! Crazy stuff.
