A dumbbell for dogs training is made of a dried wood handle and adjustable plastic discs. The discs move along the handle to widen or tighten the bite grip area. The discs are fixed with threaded clamps. Tightening the discs closer to each other you may adjust the bite grip depth. The thinner is the distance between discs, the better is the grip with dog's forth teeth without a possibility to push the whole snout forward. The discs are very strong and durable for breakage even if fallen on its rib.
A strong rope makes a dog training dumbbell more functional for your sessions with a dog. A dumbbell for dogs may be used without discs as well. The weight of a dumbbell of 650 g/1.4 lb is the international standard for dog sports. Training with this dog obedience dumbbell improves dog bite grip. All the materials used for this dog training gear are eco friendly and absolutely safe for dogs and people.
A dumbbell for dogs is not a chewing toy, but a professional dog training device. Do not leave a dog with it and do not let him play and chew it alone.
