We figured it out!
Color: 6PC-Peanut Butter-Orange, Color: 6PC-Peanut Butter-Orange
My pup wasn't quite sure what to do with it at first. It did take me a few minutes to get him to figure it out. I just kinda toyed with it like I would a rope or a toy around his mouth and once he grabbed it, I pulled it away making him wanting to grab it again and take it from me...
Once he finally took hold of it firmly, that was it, we were off and running!
It's definitely a super hard chew toy, so I surely would not recommend it for a soft jaw dog. But if your dog is like mine, with super crushing power, then this is the right fit!
