Oh Jodi!! I can't even imagine the look on your face when you opened that door!
I wonder what the other 2 were doing while Manto was having a blast making that mess... I'm sure they were saying "oooh you're gonna be in big trouble mister!"
And of course not catching him in the act there was nothing you could really do but remove him and not let him see you cleaning it all up. I'm sure he was very proud of himself too - wagging that cute little tail saying "look what I did Mom!"
Sheesh, I wish I could have at least come help you clean it up - I know you were in no mood to tackle that!
Crating him with safe things to keep him busy - you're right. Puppies will be puppies and GSD puppies will be bigger puppies that get into bigger messes!
I know it's no consolation, but I remember a couple of horrific Jack fiascos that I came home to more than once, then slapped myself in the head for trusting him in a confined space - with his crate available -
Manto has a lot of energy and curiosity right now - as you obviously know!
Hang in there Jodi- he'll calm down and be the best buddy and the dog you imagined.
