I digress by the by, Callie can open the back screen door. No sturdy latch, if he hears something impressive he charges out head first...Callie the Tank Engine

Rosie will just sit and stare at a door to get it to open, in other words wait for me to open it

Perhaps they're related to Dingoes !

"Dingoes have unique wrists in the canine world, capable of rotatation. This enables dingoes to use their paws like hands and turn door knobs. Their ability to go where other dogs can't means dingoes can cause more problems for humans than other wild members of the dog family can."
