The Aerobie Superdiscs are just terrific for use with disc catching dogs. The soft urethane edge will protect your pal from painful injury. Just as important, the discs fly very well: straight, with good distance, hover, and predictability. I've gotten frustrated with my own lack of skill in throwing other discs, but, these are almost perfect, for me. They work pretty well in no wind, but, if you can throw into a light head wind, the flights are impressive. I typically throw 100 feet, for my Brittany girl. My best throws are about 4 feet off the ground, passing her right shoulder... she'll catch every one of those. One minor annoyance is that the edge becomes difficult to grip firmly, when wet, as from dewy grass. I've made some wild throws trying to get used to that.
