Who knows if eating soap is good for dogs (a guess: it isn’t), but this would probably distract rover for long enough for you to sneak into his house and rip off the good silver.
Adapted from one of their existing products, the team at Gazillion saw the need for an automatic scented bubble blowing machine after watching a TV series on Dog behaviour, in which the K9’s under observation went utterly bananas for bubbles! The Fetch a Bubble was designed as an Ideal toy for indoor or outdoor use, and is incredibly simple to set underway. It’s series of bubble wands rotate through 13 full revolutions in one minute firing off a frenzy of thousands of bubbles per minute in a Tommy-Gun like fashion!
