I thought this would be an upgrade to the Dogobie disc that I use with my dog. Far from it. A big downgrade, actually. Within three throws, the top was punctured by my dog's teeth, making for jagged puncture holes that can eventually cut the dog's mouth. It looks great, but doesn't even fly that well in relation to the Dogobie. Still looking for something a wee bit heavier and bigger than the Dogobie. This was definitely a disappointment, especially in light of all the positive reviews.
