Everything I got in my last order from you guys, not only my gsd, but also my mal and doberman went nuts over. I call it the ‘crack box’ The training dumbbell and the rest of the items in my last order are all for training, I keep the box on the couch and even if I reach my hand toward the box, all the dogs alert and get excited immediately. The training dumbell with strings is great for getting a stronger grip on the dumbbell, I was going to make my own but lucky I found one with strings already on it!
