Booda Tail-Spin Flyer

I have purchased 6 of these 7-inch frisbees in the 5 years we've had our dog. She loves them and we use them every day. Unfortunately, the last one we received is different - the design has apparently been changed. The outer ring used to be a soft, flexible rubber material. Now it is hard and stiff plastic. This will not work for us and we had to throw it out and go back to the old worn-out frisbee we had from before. This probably sounds strange, but we play frisbee with our dog every night down the hallway in our home before she goes to bed. This activity tires her out - we've done it her whole life. The new design of this frisbee does not work because it's making marks and dents on our walls and door frames. Our dog also is confused by the new materials in the frisbee and she will not pick it up. I'm very disappointed in this, because we periodically need to replace our well-used frisbee, and now we can't do that. I will have to search for another brand. Please go back to the previous design!!!
