One of my Newf's did that when he seen a Squirrel on the deck...2 hundred pounds of dumber then dirt.....:laugh:..I had to put screen protectors on the deck door after that...
My doberman did it. She wasn't even big. Threw the firewood in the house. And said to her let's go in the house. Back porch was off the house so about a3 ft step up. No problem she came barrelin across the yard straight through the screen door. She sorta had a sheepish look after that stunt.
Had a P/U with topper so I built a shelf in the bed near the sliding rear window for my 96 lb Rottie/Staffy to lay on. I opened the tailgate for him and he went thru that slider right into the back seat. Shattered the window into little chunks.
