If both of you are out for 9hrs plus, 5 days a week, then why have you got a dog?
You really need to be home with a puppy or at least able to get home throughout the day for toileting, training and socializing. These are important months for this to be happening right now, especially the socializing with other dogs, do you take your dog to any activities in the evenings/weekends etc for stimulation and fun?
I can't believe that this little one is just left on it's own like this.
