(34,370 posts)Dogs just aren't that smart, unless they're a special trained service dog.
They may appear to be obeying to an "invisible master" but for the most part they have brains like little kids and will constantly test boundaries if not supervised. Many dogs suffer from boredom and loneliness and need constant structure.
I highly doubt if these dogs had rabies.
They were probably bored and the mom of the two kids took for granted that her kids were OK because nothing had happened previously. Just because a dog "appears" to be obeying when the owner is out of site does not mean that they are obeying. They may be tired. They may think the owner is in the room etc.
All dogs are pretty much like little kids and will test boundaries at an given time. My chihuahua was great when I was in the the room. (Better when I had her full attention) However, if I left she would often start shaking....Eventually it would be followed by crying etc.
