My dog’s figured out how to open doors, what can I do?

Hi there,

I’d like to know what I should do when my dog opens the doors? And how can I stop her from doing it?

My dog, a one-year-old Border Collie cross Lab, opens the doors. She puts one paw on the wall and the other on the handle to open it.

Because of this, we’re having to keep certain rooms in the house shut, but some doors don’t have locks so we’re worried she’ll get in and destroy everything.

Thanks in advance for your advice!
