Can dogs see or recognise humans through glass

[in a mo]

We have a Rough Collie ,when we look out through the closed window beside our back door,she gets really exited and runs around the garden but when we look through the other window on the same level there is little or no action,any ideas why .Thank you.

Is it due to whatever is opposite the windows and light? Does one window have a stronger/brighter reflection that prevents your dog seeing you through it?

Dogs can definitely recognise humans through glass. My mother's dogs always jump up at the living room window, and as soon as they see her or my father coming home, they instantly run and fetch a shoe or some other form of gift to greet them with.

maybe she expects you to come out the back door if you look through the window next to it?

[carrot99]

or conversely, that you are going to open the door for her?
