Herding Ball for Dogs 25 Inch - Dual-Layer Heavy Duty Herding Ball for Australian Shepherds, Border Collies & Cattle Dogs | Outdoor Herding Toy for Medium/Large Dogs - Backyard Training and Play

I bought one of the big herding balls like this one (but not this particular one because the one I bought is no longer available): https://a.co/d/09FetBjD It lasted about a couple of weeks with my 5 month old Aussie. She obsessed over the zipper and ended up puncturing the inner bladder after she'd shredded the zipper area a little bit. She absolutely loved the ball, just wish it was more durable. I think I spent $40 on mine. Doubt I'll get another one in the same style.
