Dog OCD???

I think my puppy might have OCD.
His name is Dewey. He is a ten month old American Cocker Spaniel that we bought from a breeder(so many issues here!) when he was seven and a half weeks old.
Now here is the problem...
Inside our house whenever something is placed in a different spot he starts barking like a madman. Whether it's the coat someone threw over the chair or the bag on the counter or the blinders going in a different direction! It all ends in the same result, insane barking (and he has one ear-splitting bark). He will also bark at anything new that enters the house and I have no idea how to correct him. He is driving my family crazy and whether it's OCD or something else it would be great for some advice. Thanks!

There are alot of ways to correct & help the barking behavior. I have a lab that has just turned 1yr, I got him from a rescue when he was 3mnths. He had the same issues, confidence is the issues. There are plenty of techniques to try to train your dog. I sat in a quiet room with my dog and some treats. Making the dog speak bark bark bark speak as loud as possible then firmly saying quiet (or leave it) & walk a few steps away not facing the dog. When he/she is quiet then reward him/her. I repeated this step a few times a day for about a week, and now he is a very happy pup that isnt killing our ears lol

Another thing is a bark off, my friend uses it but I train with rewards instead of sounds. But it def works.

Good luck :)
