The Destruction

so i came home today from running a few errands, and i was only gone for about 3 hours, or a little bit less. and i walk in my door and my dog, has destroyed the pull up blinds that were on covering my sliding glass door in the back. why i dont know. he must have been trying to jump up and chew on them, and he pulled almost the whole thing down off the wall, and all the strings broke that was holding up the attachment. so now, i dont have anything covering the sliding glass doors in my living room, so anyone walking by can see inside my house. so my first thought is to replace and buy another vertical blinds for it or something like that, but then what if he destroys them again? considering that i dont even know why he destroyed them in the first place. 3 days a week i live him alone to go to work , and i am usually gone for like 11 hours. this time i was only gone like 3 hours, and this is what happened. i know that we did have a big storm while i was gone, maybe that upset him, i dont know. what i do know is that when my husband comes home from work he is probably going to flip out. he didnt like the dog in the first place, so this definetly is going to make that worse. i dont know what i am going to do about this. other than this, he is such a good dog. he just did something like this 2 times before this, and we couldnt figure out why. i have had him for a total of like 6 months, and he has done something like this 3 times. so like an estimate of every 2 months, he does something like this. i really dont know what to do. i know, like i said before, that my husband is going to flip out. i love this dog like he is one of my kids, he is such a lovable dog, it is just this one thing that he does every once in a while. maybe if i make sure that he has some bones to chew on, and buy that bitter spray that you can put on things to prevent the dog from chewing them. i dont know. just what i needed another thing to stress me out.
