My dog (63 pound pitbull mix) LOVES to play frisbee and I have tried no less than 6 different brands before finding this one. The search is over! Previous brands I tried suffered from one of two problems:1. They were durable but made of heavy rubber or hard plastic, my dog refused to catch them and I don’t blame him. Imagine a hard heavy disc smacking into YOUR teeth!2. They were light and soft but not durable. Every day he would take his caught prize and take a couple tugs at it, I found myself replacing them every week. (I don’t even let him have the discs unless we are playing catch).This disc is really the best of both worlds. It is made of fabric which my dog likes but it is thick and durable. I’ve had the same two discs for over 3 months now and they are as intact as the day I got them. I think my dog realizes ripping them apart would be a challenge and doesn’t try.My only really minor qualm is I find for me they hook to the left a bit, I’ve had to adjust my release angle to compensate. Unless you’ve been tossing frisbees for a long time I doubt you’d notice. Still makes for a great toss though and can fly a good distance. Will be a repeat customer when mine finally kick the bucket.
