This whole thread makes me very sad.

The OP has no clue. Got a nervous shy puppy that had been returned to the breeder because it was too shy in the first home.
Got a puppy when he knew he would be away for 12 hours a day, without making any plans of having the puppy being taken care of in those hours or let out or fed.

Thinks puppy understands that it should not urinate...then calls it over to scold it and "give it a pop".
Taking it supposedly to Petsmart classes twice a week, but has no clue how to treat puppy with positive and rewards training.
Puppy is probably suffering from a UTI, because it is forced to hold urine for too many hours at a time.
What a lonely, life this puppy is having.
You've been given good advice. Get this puppy a dog walker to come over a couple of times per day...so that she can be fed, and allowed to relieve herself and have some social time.
You would have been far better adopting an adult dog that did not mind staying the day alone, and did not need so much work as a puppy.
