Query: Only Good Choice

I have a 2 year old Doberman that is not a big chewer but loves to grab a Frisbee and run with it. Every bargain Frisbee I bought for him would end up breaking apart within a week with the exception of the Kong Frisbee which lasted about 45 days. Based on reviews here I decided to try the Nylabone Frisbee and I am VERY glad I did. We have had it 4 months with no sign up breaking apart. It flies very well and actually works better then some of the bargain Frisbees I had purchased in the past. The only note of caution I would make about this product is that it will discolor if left in the sun (however that has not effected the performance).
