Not get their mouth all around it, but get their teeth into it. My dad used to have a female black lab cross (she was like 3 breeds, from the dog rescue) smaller than yours. She managed to pop a surprising amount of kids ballsUnless your dog is absolutely enormous they can't get their mouth around a properly inflated soccerball. Mine's 86lbs and stands about mid thigh high, and she simply can't pick up a fully inflated ball like that, but I imagine some bigger males could.

It wouldn't be guaranteed that she'd pop it, but there was about a 30% chance.
