Up until our current pack of monsters none of the dogs paid much attention to the 'bots as seen in video of Ned Mastiff above. Several times, and I'm so sorry I didn't ever get a picture, I would hear a hard plastic object go bouncing on the floor or deck. It was Cissy Briard with a 'bot that had gotten hung in her long tail hair. She never freaked or didn't even seem too annoyed by it. I think spending most of her first year with glued up ears and the constant attention they needed and so many hours on grooming table, being subjected to so many things, she probably experienced the 'bot "attachment" as just another thing she was expected to put up with.
Our current five aren't very interested in them but are less tolerant. Current Bubs are allowed on furniture, a first for us, so they usually get up on sofas when 'bots are running. The Bubs before them would usually just let the 'bots bump into them and clean around them or sometimes get on the big doggie beds. The Dirtdogs bump harder than the Roombas so they usually didn't put up with too many bumps from them before moving.
In 12 years we never had any freak, bark, or attack them except for this...........
