Our old agility club had one of these for anyone to play with and Lexi really liked it. It got dirty/gross really fast there but I blame that on the big slobbery dogs and the fact that it was always outside.
We just bought one for Christmas and like it. I think I still prefer the Soft Bite Floppy Disc, but the Squirrel seems to float in the air longer.
I allow Lexi to tug on her frisbees so I know the squirrel won't last as long since it has plastic edges, but I think it will still hold up for a while because I don't allow her to just chew on it or let her have it unattended (she would definitely chew the plastic).
