We've had too many incidents of the puppy throwing toys around if he wins a tug with us or the other dog. We've had those tennis ball tugs bang into the tv and other stuff, so they're now relegated to outdoor play, only! So, they have Fat Cat Toys...rings, tug-ables, and ones that look like different animals for tossing and other inside use. They're made out of something like a heavy canvas. We haven't had any more crashes, and they've held up better than most toys seem to with these guys. Several we've had for 3+ years. They sell them at Target, and I think Walmart. Hope that helps!
