Thank you all for your replies.

Catsanddogs, I am very sorry on the loss of your beloved dog.
May he Rest In Peace.

I totally agree with everyone that the puppy needs to interact with his owners. I made a point yesterday and most of today to check about every half hour on the situation and this is how it went. I would stand and watch for about 10 minutes. Puppy was let outside this morning around 7:30 and let back in around 8:45. Then was let out again at 10:00 and let back in at 11:30. Out at 2:30 and is still out at this time. It was laying on the blanket chewing on a bone or toy.
The puppy doesn't seem to bark or whine when it is out. As for pooping or peeing on the balcony, I can't really say if it does or not, as I haven't seen it squatting at the times I have been watching. Maybe this is the way these stupid people are toilet training the puppy, who knows.
Regardless, I still don't like to see it standing at the door looking in.

Now, I also finally got a hold of the Animal Control and they told me that since the puppy is NOT out all day and the weather isn't too bad at the moment and it has a blanket to lay on, that there is nothing really that they can do about it. But, if I do see that the puppy IS out all day and the temperature has reached freezing, then they will come out to check on it. They also said that from the sounds of it, the situation seems to bother me more than it does the puppy and that the puppy probably enjoys being outside.
This is true that it does bother me as I also think that it should be in the house.

Thank you all again for your replies and I also agree that if you are going to get an animal, be responsible and give it the attention, love and care that it so rightly deserves, don't just put it outside.
