Query: Tested by Nikki & Sophie - Fail

If you only have one dog and you buy this flyer, then it's probably o.k...although it's not unlike throwing a piece of rubberized lead. However, if you have TWO dogs that like to compete in returning the flyer, ...Fuhgettaboutit. I threw this flyer out in the yard and it lasted 15 minutes, ..tops. When I got it back after five or six tosses it came back with a 2 inch rip on the inside edge of the tire. Bummer. I'm sorry to say its just more money wasted. We have tried so many frisbees and flyers and Nikita, our Australian Sheepdog and Sophie, the Whippet-terrier mix shred tham all. I am praying for a frisbee made of Kevlar. Meanwhile... the search goes on for a really tough frisbee. Aloha! (p.s Maybe Mammoth might consider putting steel belting in their tires)
