Subduing them with tasers obviously wasn't the answer.....

Boxers aren't that big, really, and the "attack" on the child was pst tense. It sounds like the officers had cornered the dogs and then tased them. There are no mention of any injuries to anyone other than the dogs.

That being said, the same non-lethal force used to apprehend criminals (net rounds for shotguns) would have worked perfectly well.
