Watch What Happens When This Pug Discovers An Invisible Door

Little Lola is having a real multi-sensory learning experience as she meets "the sliding glass door." This Pug doesn't seem to be to impatient or even a little anxious about the fact that this big see-through glass thing is not budging or changing form one bit, despite the various tests she tries out.

Clearly, the concept of an invisible door that's holding her back from getting to the outside is something she hasn't quite grasped. Watch Lola as she tries out all her options to determine why she's stuck where she is and can't get where she's trying to go!
