Underestimating the stability of glass led to an embarrassing lesson for the hasty star of this clip. <br /><br />"We had taken our 11-week-old puppy, Bruce, outside for a wee, and he thought the back door was open since it’s glass, so he tried to run straight through it!" the filmer, Ellie, told WooGlobe. <br /><br />The playful pup learns the hard way that slowing down near a glass wall or door is always a good idea. <br /><br />Thankfully, Bruce’s loving human is right there to comfort him and provide the care he needs after the comical mishap.<br /><br /><br />Location: Farnham, England<br /> <br />WooGlobe Ref : WGA201130<br />For licensing and to use this video, please email licensing@wooglobe.com
