Clean glass is pure hazard! Literally every person, or at least ninety nine percent have mistaken a closed glass door for an open one! And we can bet that the pooch in this video suffered from the same accident at some point in her life.
How do we know that? Well, look at how reluctant she is to enter through that back door even though there is obviously no glass there. As they say, once bitten twice shy, and this pooch was obviously bitten! Look at how carefully she is examining whether there is glass there or not! It’s absolutely hilarious!
