Firstly, welcome!

Secondly, hehe, Bryan, your dogs are just being puppies. Consider yourself VERY lucky. Destruction 1 out of 4/5 times is a very very very impressive rate. Your 6-month-old puppy has amazing self control. Heck, I can't even take a nap without crating Ivy. That's how she destroyed my glasses, my iPod, various books, various handbags/backpacks, several shoes, socks, etc.

Until your dogs are aged and wise, keep them in the crate. Otherwise, you've got a really really greyt puppy
