Get a Field hockey ball ? or is it a Lacrosse ball ?
I got it after a game they left a couple on the fileld
or one that you can hide treats in
I'm not sure, I can't remember the name brands etc.
I've had these 2 balls since like 1980-ish, gone thru 6 different dogs, 3 labs, a pointer,
and a set of male & female American Staffordshire Terriers (strongest jaws I've ever seen)
& a Belgian shepherd, who'd destroy every toy he could get his mouth on
other than those 2 balls
you'd be amazed even a soft mouth dog (like a purebred lab) can destroy stuff
If you let them
not good for inside play, rock had plastic one with hole/rock hard rubber & heavy,
you will break ****, ask my kids
but outside, plenty of fun
