I assume anyone could effectively make the same thing with a $20 RC car and parts from an old microwave, or something equally mundane? This feels less like news and more like posturing. The news here isn't necessarily that they've taped a cell phone jammer onto a boston dynamics dog, the news is that they are testing the waters with militarized robots for domestic use. Proverbial "Whatcha gonna do about it?"
