The center bar of this SCH1 dumbbell is oval shaped instead of round.  The oval shape makes it hard for the dog to turn or roll the dumbbell inside their mouth and will help prevent chewing.  Many trainers find this product especially useful in the early stages of dumbbell training.

Redline K-9 Schutzhund Obedience Dumbbells are turned from a single piece of solid Maple and coated with a non toxic Paraffin wax to help keep the wood from cracking during the change of seasons.
