The 6 Best Toys to Keep Your Dog Really BusyAnna Jane Grossman - Thedo.gs5/24/12 12:00pmFiled to: DogsToysGadgetsTop1263EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkMemorial Day is coming and, if you have a dog, you would probably want to keep him or her busy while you honor those who fought on countless battles to preserve your freedom to stuff your face with BBQ'ed burgers and ribs.AdvertisementDog training expert and longtime Gizmodo collaborator Anna Jane Grossman has picked the six very best toys to do that. The KongThe granddaddy of all work-to-eat toys, the Kong is a chew toy made of nearly indestructible rubber. It was originally based on a part of a Volkswagen bus' suspension device that the creator's German Shepherd found particularly irresistible. Kongs can be stuffed with a wide variety of yummies. Kong sells especially shaped treats and different things you can squeeze inside, but you can stuff it with whatever your dogs' weakness might be: cream cheese, Cheez Whiz, wet dog food, peanut butter, liverwurst, frozen blueberries, hamburger meat. Yummers.There used to be a great product that operated on a timer and dispensed Kongs at intervals, so you could stuff four of them and then leave for the day and your dog would get them doled out at neat intervals. The product was discontinued a few years ago, but you can occasionally find a used one on Ebay, and they're well worth the $100 or so that they usually sell for.

It comes in a few different sizes. The yellow part at the top screws off, allowing you to put kibble inside, or any kind of small and fairly hard treats. If you feed your dog kibble, you can put his entire meal in this thing. It makes mealtime last ten times as long, which is a good thing for reasons both behavioral and healthful.AdvertisementAdvertisementMy dog Amos eats about four of his meals from it each week. A tiny sliding door over the outside hole and a movable flap covering the internal one makes it possible to basically set it to different levels. Here, Amos demonstrates how to use it. I had the outer door flap mostly closed here, so you'll see there isn't much food coming out at a time. But never fear: Eventually, he did get it all.Kong makes a similar toy, the Wobbler, which is just as good except that there are no doors or flaps, so the levels can't be changed.The Tricky Treat BallThe Tricky Treat Ball is similar to the Bob-A-Lot. There's a single hole in which you put in kibble or treats and they fall out as the dog pushes it. Much enjoyment will ensue. Your dog will continue to play with the ball after all the treats are gone–he'll be holding out hope that maybe there's still one lodged in there somewhere. He'll also keep playing with it because, like so many humans, dogs like balls.The Tug-a-JugHere, the human puts dry food (kibble, treats, Cheerios, whatever) into the Tug-a-Jug, which unscrews at the bottom. The food comes out of a narrow hole at the top, which has a rope sticking into it. As the dog pulls on the rope, some food gets dragged out. Your pup will have crazy amounts of fun swinging this around and tugging at it. It comes in several sizes to accommodate different size dog mouths. I find that the rope usually doesn't last too long, but Premier does sell replacements–and sticking an old knotted sock halfway in pretty much does the same job. (I only recommend this toy if you have carpeting or really tolerant downstairs neighbors - it can bang around a lot.)The WaggleStuff dry food into the sides of the barbell-shaped Waggle and the bits will fall out intermittently as your dog holds the middle part in his mouth and shakes it. Well, that's supposed to be how it works, at least–my dog prefers to just kind of roll it around with his paws until the treats come out. That works too. There are rubber teeth in the holes on the sides that can be snipped out in order to reduce the level of difficulty. Premier also makes the Chuckle, which is similar but a little sturdier and has a squeaker inside.The Dog CasinoThe Dog Casino is a one of the many fine toys by Nina Ottosson, a genius Swedish pioneer in the world of interactive dog puzzle toys. Her offerings come in a variety of levels of difficulty and in both plastic and wood. This one is the first that my dog Amos tried out, and he loves it. I started him on it by taking out all the bone-shaped light blue pegs until he learned to pull open the drawers with his paw. When he got that, I put some of the pegs in –they act as locks. So then he had to pull out the pegs before the drawers could open. Here he is with just one drawer left to unlock.AdvertisementSponsoredMany of Ottoson's line of toys require that you work with your dog a little bit to help him along. It's really fun to watch them solve the little mystery of each game, and to figure out how to help them get it. With Amos, I first rewarded him for just touching the handles with his paw or nose. When I withheld a few rewards, he started to get annoyed and his pawing increased until he managed to get it open just a enough to lead to the big reward inside the drawer. The magic of learnin'! To help him figure out to life up the pegs, I smeared peanut butter under them.Now that he's a pro at this one, I often put his entire dinner in it –wet food or dry. But I only put them in some of the drawers. That's why this is called The Casino, after all.Anna Jane Grossman is a journalist and dog training expert.
