Oh I know the feeling all too well! Bon is 9 months and is even crazier than when he was 4-5 months old. I think it just took him longer to get into the silly puppy stage. Our only problem is that he's not just a puppy, he's a 120 lb puppy
I know for us it will probably be another couple of years, but that's ok...we knew all about it before we got him

So don't feel bad, your not going through it alone!
