Malinois proof
Color: B) Medium 3" Ball
So far this has held up great. My Malinois who has destroyed nearly every ball I’ve gotten her, this one has lasted over 3 weeks without a dent, compared to some that don’t even last a day lol. Although the medium size is a little too big for her liking she still plays with it. It’s very durable and I like the middle part for engagement as well. I would recommend if you have a dog who destroys every ball possible.

Actually Durable
Color: B) Medium 3" Ball
One of the few "heavy duty" toys that my pittie hasn't destroyed after a couple of weeks. Most of them last two days. She's an absolute beast so I'm confident if she can't destroy it, few dogs can.

Not for aggressive chewers!
Color: H) Infinity Ring, Color: H) Infinity Ring
Not for aggressive chewers! Done for in about two minutes. I unboxed this and tugged with my Mal for a but then let her have it. Within minutes she had chewed through it. Not worth the money.
