The Kong Wobbler reminds me of Weebles, a children's toy from Fisher Price. The Wobbler works on the same principle as Weebles - it's an egg-shaped gadget that's weighted on one end and spins and rolls anytime it's nudged, eventually righting itself. The Kong Wobbler is described as a dog treat dispenser and feeding toy. It's made up of two halves that unscrew to allow for easy filling and clean-up. Once filled the Wobbler will dispense whatever is inside through the hole in the center as it spins, rolls, and wobbles around. The Kong website doesn't actually say much about the product so the following description comes from petsmart.com:
The Wobbler unscrews for quick filling and easy clean up, and is top-shelf dishwasher safe. It is great for playtime, providing challenge and physical activity the whole family will enjoy watching. It also presents and excellent alternative to the traditional food bowl, extending the joy of feeding time and preventing unhealthy gulping. The Wobbler is made of a durable, FDA food-approved, high strength polymer and can accommodate up to two cups of food.
I only use the Wobbler occasionally as a treat dispenser to keep Andy entertained. I like to fill it with a small handful of kibble, anything more than that and I'd actually have to start counting the kibble towards Andy's daily calorie intake. Once the Wobbler hits the ground it only takes the pup about 5 minutes to get it empty...but boy does he have a good time doing it! It's quite entertaining watching Andy knock, push, and throw this thing all over the place. With that in mind, one thing to consider with the Wobbler is that it will get knocked around, and rather violently if your dog really gets into it - so make sure the floor is clear! I'd also recommend only giving the Wobbler to your dog under supervision. We have a small size Wobbler and once Andy gets it empty he always picks it up and takes it to the couch to try to gnaw on it. The plastic is hard and durable but not indestructible.
When the Wobbler is not in use I like to store it on a shelf - out of site and out of mind for Andy - this way when I take it out he gets really excited. I also like to wipe it down after each use and wash it completely every couple of uses. Cleaning the Wobbler is a breeze - the two pieces unscrew easily and I simply run it under the sink and wipe it down with a soapy sponge. Now I got our Wobbler at a HomeGoods store for $9.99 - the small regularly retails for $15.99 while the large sells for around $22.99. I think the toy is worth it for $9.99 - anything more than that and I personally would think twice about purchasing one. Maybe if it was on sale I would consider it but not at retail, especially considering Andy only plays with it once every 2 weeks or so and each "session" only lasts about 5 minutes. All in all the Wobbler is an entertaining and durable toy...but try to find it on sale if you really want one.
