Hehehe Just an expensive knock off what mushers have been doing for YEARS (ie, baited water). You can this stuff yourself by going to your pet store or even local drug store get multivitamin supplement (make sure you figure out the proper dosage), dissolve into the water, add cut up bits of meat and voila! Different people add different things, some add electrolyte powder, others add calcium or vitamin C, all depends what you want your dog to get. If you heat up the water a bit it tends to take on more of the meat taste.
Another way to do this is instead of adding meat, poor the water with the vitamins and such over your dog's kibble.
