"My 7 month old Weimy has played with this Rope Toy every day now for over 3 months! He chews on it, tosses it around,plays tug with my teenagers,tries to untie it, and carries it around with him. He has often played with this toy intensely for 40 minute intervals before exhausting himself mentally. Anyone who knows the high energy level of a Weimy pup knows how hard it is to find a toy that offers that much non-stop interest to such a hyper baby. He has untied one of the end knots to make this a flopsy-mopsy rag-style toy, which has enhanced his enjoyment that much more. He has only managed to pull off a few strands of floss, but the durability of this toy is superb, very well constructed!"
