These are like the land-based version of aerial drones. They can work as networked teams, detecting, tracking and intercepting; enhancing command and control, and assisting with logistics (resupply, transportation, medical support).
They can move around to monitor an area, and include a whole suite of different sensors (like night vision, IR/heat detection, sound, RF, vibration, LIDAR, radar, etc.).
They can improve detection and tracking capability for a guard force. A force multiplier.
Like the aerial drones, there is no technical constraint to arming robot dogs with lethal or non-lethal weapons, to assist with intercepting, capturing or destroying threats. So it is likely that they will eventually begin to pack some punch - some bite will likely be added to their initial bark.
Land-based drones or robots have several advantages over flying drones.
They can persist in areas for much a longer time, hiding in low power mode, or connected to a charging station.
They could more cost effectively do heavier tasks, like carrying a restrained prisoner or casualty through rough terrain/vegetation. or providing direct assistance to officers operating in dense vegetation, like hunting dogs.
Initially, they will likely just be more eyes and ears, but gradually they will also become like pack animals doing work, and like team mates in confrontations with law breakers.

Noses, I want more dog noses:)
And they will be immune to ‘doggie treats’.
