Benn Jordan has a new video where he gets one of these and hacks it. They are incredibly insecure and one could conceivably get one and program it to roam around and hack other robot dogs and assemble an army.
There's more in the video about how they connect to servers in China. Normally I'd suspect it's fear mongering, but it does seem like the company spent nearly zero effort to protect the hardware from hacking and tons of effort to prevent someone from figuring out they phone home.
