SportDOG "WHITE" Jumbo Plastic Knobby Dummy

The jumbo white dummy — full-size challenge for serious water work

White sits up clearly on open water, making it the natural choice for water retrieve training where visibility at distance matters. In the jumbo size, you get a dummy that more closely matches the weight and bulk of real waterfowl — at 3" in diameter and 12" long, this is noticeably heavier and thicker than a regular dummy, and that difference matters as a dog advances from basic marks to longer, more demanding retrieves.

Many trainers introduce jumbo dummies once a dog is reliably retrieving the regular size and ready for a step up in difficulty. The extra weight changes the carry, challenges a dog’s grip, and more realistically simulates the feel of a mallard or Canada goose. For dogs being conditioned for waterfowl hunting, running hunt tests, or working longer water marks where a regular dummy doesn’t challenge them anymore, the jumbo is the logical next step.

Same construction, bigger profile

The soft plastic vinyl construction is tough enough to take thousands of throws and retrieves without cracking or splitting, but pliable enough in cold weather that it won’t become hard and uncomfortable for your dog to carry. The knobby texture gives your dog a firm, natural grip and is specifically designed to discourage hard mouth. The air valve lets you adjust buoyancy for any training scenario — fully inflated for high-floating water retrieves, partially deflated for a lower-riding, more advanced water marking challenge.

Regular vs. jumbo: The regular dummy (2" x 12") is the standard starting size for most retrievers. The jumbo (3" x 12") is the better choice for larger breeds, advanced training, or dogs being conditioned for waterfowl work where bird weight and bulk matter. Throw rope is not included.
