I thought I’d seen it all when it comes to dog treats, but this is excellent and exceeds expectations.  If you have a dog with loads of excess energy and little space for him or her to spring about, then try bubbles: Bacon-flavored.  

Bubble Buddy is a toy designed to offer stimulation for your dog while holding interest with the yummy sent of bacon or chicken along with a burst of flavor each time your dog chomps down on a bubble.
