Herding Balls are made by Boomer Ball.com.  I think they are the very same ball but they cost 90.00 compared to 15 dollars for a boomer ball.

 I had to burn my boomer balls up because Casey became obsessed with them and was actually wearing her canines down trying unsuccessfully to pop the ball.  I have much better luck with the Jolly Balls.  The dogs like them but they don’t become oc about them.  Even if they pop them, they’re still able to play with them

Boomer ball.com specifically mentions only small herding dogs like aussies and borders to play with these Herding Balls.  I think it’s because they can’t open their jaws wide enough to wear their teeth down on these large balls  while with the larger breeds it is a distinct possibility.
